5mm) , large quantities of cost that estimate production are low (processing expends 1000 yuan / T is controlled) . Our country stalks or branch from Italian a place of strategic importance from 1986 (SERCONSULT) the company introduces product line of chromatic door window, already had product line of profile of window of many 70 door at present, productivity achieves 150 thousand tons of enough to satisfy the need of door window industry. At present profile of window of domestic steel door produces the forming machine that manufacturer place uses, what basically manage with Ke Gong of a place of strategic importance is similar. This kind of forming machine is mixed by frame of roller of 24-32 path level commonly composition of Jiao Zhigun frame. Shape by profile requirement configuration is different and auxiliary be out of shape roller He Ligun. Horizontal roller is transmission frame, assume metabolic main task. Auxiliary roller is passive, establish become at occasional of two levels roller group establish, main effect is pair of Ping Gun cannot the blind part part of squeezing ramming is out of shape, the line that reduces horizontal roller second. Setting establishing roller is inside the same plane of horizontal roller pass, the ministry side use a few finally shapes. To biting a mouth close street face, set the part such as fuse, pull rod, impress gnawing a mouth even. Pursue type of roller of window of 2 steel door is successive 1- takes schematic diagram of Leng Wancheng craft a 4- of preform of 2- uncoiler 3- is right solder platform 5- heats 6- sticks velar 7- to enter makings 8- forming machine 9- assists roller 10- drive stage 12- flies to Jiao Zhi of Ping Gun 11- curium cut off 13- . The cost below machinery pressing is inferior, the operation below hydraulic pressure pressing is convenient. Transmission way is type of universal drive shaft, fluctuation level roller can have bigger adjust range, in order to get used to the production of profile of window of much breed door. Be facilitating roller change, side frame and motherboard are the hinge join that can retroflexion more outside. The average production technology of profile of window of colour board door is: Also have a company to reduce cost, skipped infrared ray heats and stick velar working procedure, below this kind of circumstance, to shaping the surface of rolling roller and manufacturing control have higher demand. 2, even if cut the basis of next makings,profile spreads out dimension computation profile to develop measure is affirmatory. Normally theoretical calculation is worth the basis to determine basic measure first in production, make according to actual rolling circumstance next a few adjust. If algorithm is chosen weller, the computer also can give out directly accurate result. Can analyse width of law computation preform by the graph commonly, complex section should undertake mathematical calculation with computer program. Makings is wide decide by length of section neutral line normally. Think neutral line does not endure a turn to fold or transverse drawing is out of shape commonly. The result that computation gives considers a turn to fold place metal to attenuate to reach transverse drawing and try to amend again. Profile of window of a door, no matter how its external form is complex, always by what comprise with circular arc unit point-blank. Want to decide one gives the bandwidth that profile place needs, differentiate it to be mixed for straight line segment circular arc paragraph hind, spend to each end length along neuter line have sue for peace. The width bringing semifinished product of correspondence of each bending section is mixed by the size of angle of bend the radius of bend of correspondence of neuter line place (call nominal radius of bend, place is definite, namely the W in type of W= Rm α- - bending section length, mm; Rm- - nominal radius of bend, mm α- - angle of angle of bend, rad.

Rm of nominal radius of bend is: The R in Rm =r+kt type- - internal diameter of angle of bend, mm K- - coefficient (curve factor) T- - the ply that bring semifinished product, mm.

The numerical value that different investigator chooses to curving factor K is different. Kaertepuluofeier (the K that Kaltprofile) recommends is worth as follows: The United States " metallic manual (the 9th edition) " commendatory K estimation calculates formula to be (refer to graph 3) to pursue the metal of relation United States of position of 3 neuter lines and R/t of opposite radius of bend learns to recommend press watch computation K is worth: Press German DIN6935 standard, the computational formula that K is worth is: K=0.

5lg(r/t)] K=0.

5 it is OK that type should go up when R/t>5 rearrange is: The formula that calculating board bandwidth spends has a lot of, need those who notice these formula to derive the condition reachs its suitable scope. Proksa method is a basis nonlinear differential equation is formulary, by Long Ge - library tower (Runge-Kutta) the law is begged go out; Bogojawlenskij method is reached by mathematical statistic method, apply to thick 1-8mm of U section wall, r=5-35mm, 0-90 of angle of bend is spent, board belt width is 100-350mm; VDI3389 of standard of German engineer association is out of shape according to the brim horn is 90 degrees accurate test result to reach, apply to V or U section; Oehler method applies to angle of bend to be spent for 30-150. Anyhow, curve factor K value to basically depend on curve internal diameter and the ratio of the ply that bring semifinished product, and basically have nothing to do with the size of angle of bend. It is like internal diameter of angle of bend 0, angle of bend is respectively 90 when mixing 180 degrees, corresponding bending section length is 1/3t and 2/3t. Accordingly, in the computation in actual production the width that bring semifinished product considers the impact of R/t only, material is decreased in the place that bend horn thin the influence that needs to consider data when more or the intensity of material is very high. Graph 4 30 makes the same score window material section 4 it is a patent product, a 30 makings that make the same score a window. To a such more complex section, using the computer to calculate is very convenient. Next watches gave out to press the data that different and formulary computation reachs. Express the 30 smooth makings opening a window CAD that spreads out width computation to be worth mm3, roller (CAD) the technology is current cold curved profiled bar forward the way of high accuracy develops. Expect with window of door of chromatic armor plate model for exemple, to assure sex of good air-tightness, watertight, makings production public errand is in ± 0.

3mm left and right sides, the production public errand of corresponding ground roller also should be controlled in 0.

02 ～ 0.

Between 03mm, this to complex outline sectional for, reach with common artificial design handcrafted for be impossible to achieve. To industry of cold curved figuration, simple CAD system assists plot to be main function with the computer. When be being designed as a result of handiwork, cannot go out in a piece of picture on blueprint 2, 30 second be out of shape roller spends a figure, need to have the transition of coordinate when designing each roller consequently, make succeed in one's scheme considers workload quite big to mix trival. Benefit maneuver considers machine constructive simplified greatly this one process, adopt the special program of the work out, can make roller spend graph and roller figure immediately. But solve computation to make only the graph is far insufficient. Door window material requirement has good air-tightness and watertight sex, geometrical precision demand is high; Exterior quality demand is extremely high also, do not allow abrade color coating; And the ply of chromatic armor plate is general thinner (0.

6-1.

0mm) , board belt makings is wide amount to 200-400mm; This produces the cold curved limitation such as warp and cockle extremely easily, it is the problem that solves urgently in project application at present. Had solved this one difficult problem to have general application value to craft of cold curved figuration. Industry of cold curved profiled bar uses computer technology begin from the pass design of roller, the CAD of roller (namely CAD) the technology already had history of nearly 10 years in domestic application.  problem is to be in how old on degree but " auxiliary " people completes a design. General CAD was replaced artificial computation and give a picture, shortened the design of roller is periodic, but the remains geometrical relation and architect practice experience that this kind of design depends on. Current CAD should develop to higher administrative levels. It is the deepness development to oneself connotation,  analyses the stress of figuration process, meet an emergency with computer technology, provide imitate means to decide figuration craft, offer best roller design for actual production. 2 it is the scope progress that expands to extension, finish roller to design not only with computer technology, come true even auxiliary make, control of manufacturing management, cost accounting, quality, realize a design to make unifinication namely (CAD/CAM ) it is the computer assists a project even (CAE) with the computer compositive make (CIMS) technology. The COPRA that develops by German Data M is to solve roller turn to shape the compositive software of the design. To the user, a roller of good cold curved profiled bar designs software to should have good interface, can get used to different rolling mill parameter,  can realize the design of a variety of methods. COPRA is a when move in platform of the AutoCAD on personal computer outstanding software,  this software induces systematically the academic positive result that summarized domain of cold curved figuration, relevant standard standard and much experimental data and experience. Calculable show curve level of meet an emergency, computation the spring back of all sorts of material, optimize figuration process, the user is OK oneself define parameter to stock a database. From section the design is made to roller, the whole process of cost accounting can be finished immediately by the computer. The academic system of due and complete, system supports CAD of cold curved profiled bar, for example width of calculating board makings should provide the computational means such as concerned occupation standard or Proksa, Bogojawlenski . According to different material, give out result of spring back computation, parameter of correction roller design, can design chromatic armor plate, stainless steel board, the alloy of a variety of metals board etc. According to section computation gives coordinate of sectional area, weight, centre of gravity, geometry quantity of inertial quadrature, sectional model, turn round geometry coordinate of center of inertial quadrature, load, break firm parameter computation, for section the design offers basic and mechanical parameter, provide basis of analyse of deformation force credit to produce process. Stress, strain gauge calculates a function, use energy method of FEM,  to wait to be out of shape to cold turn the process is calculated, give out distributinging state of value of the greatest strain, stress, optimize design result ceaselessly. The database governs a function, data of the industry standard that memory user defines oneself, test, experience is formulary, memory and the profile section material that run this company, roller data, inventory management. Can undertake the cost accounting of roller, give out directly curium the weight that cuts roller of next makings watches, finished product. Before undertaking roller of cold curved profiled bar is designed, want to decide the parameter file of rolling mill first. Like the permutation of aircrew roller the drive of diameter of the position of axes of means, roller, drive, each sortie is compared etc. These parameter can be inputted by the means of man-machine interaction, also can write into corresponding data file. A manufacturer can press different set, decide file of a few parameter, the rolling mill file that correspondence should choose only when the design can. The concerned parameter that roller designs, make the same score length of the the dimension of internal diameter structure of roller, biggest axial for example, the the biggest, smallest diameter of roller, establish roller inside aperture structure dimension can decide by parameter file. To particular manufacturing company, afore-mentioned parameter need to decide only can. When be designed actually, want to input sectional over all dimension only, the computer can eduction each second roller spends a figure,  can use the editor module of roller to design the part drawing of a roller subsequently. Because design software is OK the basis is given parameter, design and assemble a relation what coach the architect decides each roller, consequently the installation of roller, adjust won't give any issues. Once exceed limiting value, can get an error or warn information. The architect can understand beforehand next roller and on the clearance of roller roller annulus, whether can produce collision, whether can the biggest diameter of roller exceed the biggest mouth of frame to spend, and whether is there enough place to do mark chamfer on the end panel of roller. In general computer design software although included dimension to tag a function, but line out of ground of one by one is full dimension, still be the as dry as a chip work with painstaking take time. Provide an user a special software package that applies to dimension to tag, this includes sheet tag automatically of roller dimension, tag automatically of dimension of ichnography matching roller, tag the function such as pass dimension automatically. Dimension is tagged is carried out automatically, the user can move to tagging dimension and revise. Because this one process has automatically, not only can save many time, and the leakage that can avoid measure is noted and complex bid. According to different user demand can choose different measurement to tag a method. The architect can be tagged automatically of choice roller outline, the automatic measure that applies to CNC Machining requirement is tagged. Those who need a specification is, use treatment of method of computerized numerical control to want to press photograph node and tangent means to tag dimension, the time that can save numerical control process designing so and avoid a mistake. The roller plan that has keyway and mark chamfer and assemble ichnography to be able to be drawn automatically. Blueprint can press the means scale of the half analyse of make choice of or full view. Use this software for convenient user, developed corresponding Chinese character to change an environment, offerred Chinese bill of fare, chinese dialog box. The user can choose a plan conveniently with caption column, surface roughness of surface of outpour of our country standard and form can be pressed on the graph tolerancepublic errand, draw up with the Chinese character the technology asks to wait. In the past, want to design good roller, the architect must have rich practice experience and " technology absolutely a key to do sth " . In affirmatory figuration craft namely when roller spends a design, main decision is made by project technology personnel. After the design that completes a roller, the design is successful, whether can give serious problem to wait in debugging a process, it is the problem that design personnel pays close attention to very. Existing most software can make geometry design only, have not offer a kind reliable examine beforehand, the method that evaluates design quality. The advantage of the CAD, should not be economic and artificial merely, shorten the design is periodic, more important is to realize what artificial design cannot accomplish to curve figuration imitate technology, make the architect can forecast actual result through the computer. Use the strain that is out of shape technical simulation software can give fore-and-aft happening with the shortest time computation, get with finite yuan of similar accurate result. User basis these new imitate methods, need not large computer and professional software engineer are designed with respect to the roller that can optimize his. Roller bends the process of figuration to be able to give out by this software imitate. The chromatic graph of generation shows board makings arises in where clearly excessive be out of shape, to avoid to design error is mixed optimized a design to offer intuitionistic and reliable decide according to. More complex to makings section and board thinner chromatic stencil steel and window of stainless steel door, should make its do not appear in curving a process the blemish such as wave, ruffle, the most important is to make its are in of figuration fore-and-aft do not produce plasticity strain. Newest research achievement makes clear, no matter much thinner board makings, in be out of shape the condition of meet an emergency of the area always can have drawing and reduce two kinds of strain hand in change, and drawing and compression strain are in board show again on different level distributing differently. Be in only board the stretch limit that each assure to the meet an emergency that the area that be not a turn nods each does not exceed material on the layer, ability assures steadily figuration. Downhill law figuration is in the roller design of cold curved profiled bar is commonly used method. The purpose of this kind of method is to make area of board base brim gets meet an emergency of the ministry side the smallest. To make calculation simple, use rolling normally fiducial the method that waits for a quantity to drop. Recent research makes clear, this kind of rolling is fiducial the method that waits for a quantity to drop is not value of meet an emergency is the least. One kind calls the figuration method with frontier department the smallest meet an emergency is to only have the aid of comes true at the method ability of the computer. Cold to the Bao Bi of tall section curved profiled bar is produced, means of this kind of figuration is available better brim quality and the manufacturing defect that reduce rolled piece. This one new imitate technology can apply on the PC, this suits the situation of our country enterprise particularly, learn for the user, improve roller to designed a technology to provide a means. Although the user does not have computer experience, or lack design experience to also can choose viewpoint beforehand, show the three-dimensional view of all roller according to need, watch whole figuration process from upside or flank. Deny make friends to give the section of bigger norms to function of little roll steel, the result that also can show according to the computer sentences phasing adjacent roller to whether can generate interference. Imitate technology can give out according to parameter of different material character, rolling mill corresponding result, all sorts of Leng Wanyi sectional figuration can give out the result that meet an emergency analyses. In addition, this one technology is improved to the manufacturer of equipment of cold curved profiled bar and optimized aircrew parameter to provide very good means. Graph 5 it is to use COPRA to realize 30 smooth makings opening a window model be out of shape the part second process imitate. Graph 5 realize 30 smooth makings opening a window with COPRA model be out of shape we ever used process simulation of this software be out of shape imitate technology is many manufacturer of domestic to make simulation of beyond the mark analyse, of the result that the computer gives out and actual condition be identical quite good. A few material that produced in the past, although also used computer design, but can design pass according to geometrical relation only, cannot be judged to actual rolling circumstance and imitate, a few problems also had appeared in debugging a process. We use this one new imitate technology test and verify, result and actual condition agree completely. Had imitate medium, design quality can use optimization technology, our Ceng Gen occupies the existence condition in user factory, use 5 to be out of shape what finished a when make for 11 ability formerly serious asymmetry is sectional, try make friends success. 4, profile of window of colour board door is out of shape craft and design characteristic profile are out of shape craft graph common says roller spends a figure, it is the finished product section according to profile, according to with shape ordinal and contrary measure spreads out, overlay is inside same plane, resemble an open pattern. Adopt such pattern plan, the architect can understand profile be out of shape circumstance, configure corresponding roller pass. Graph 6 it is a graph 4 be out of shape craft overlay pursues sectionally. Graph 7 it is this makings model be out of shape craft forms a plan. Graph 6 30 is smooth makings opening a window be out of shape 7 30 of plan of craft overlay plan makes the same score a window makings be out of shape craft arranges graph colour material of window of board steel door uses chromatic coating armor plate to be roller of raw material classics to bend figuration craft to be made. Close to make sure the intensity of door window is used sectional. Solder the method will destroy armor plate surface, used structure gnawing a mouth extensively consequently. Interfere to avoid medium happening to bite buccal procedure, avoid the loss of pair of chromatic coating surfaces, the airtight watertight sex that also assures door window at the same time and cooperate a requirement, requirement roller design and make achieve taller precision. The ≤ of Ra of exterior surface roughness of roller 0.

63 μ M, the circumferential speed of roller approachs drive rate as far as possible, when the linear velocity difference that is like roller is bigger, idling structure should be used on the design. Graph 8 use at colour material of board door window auxiliary roller assembles sketch map to shape to general roller turn, figuration roller axes is a level or perpendicular two kinds of configuration. Makings gnawing a mouth the auxiliary roller that figuration used dimensional structure extensively, installation of structure of this kind of complementary roller is in two advocate between roller, roller axes can be aleatoric banking angle to spend, its configuration is different from advocate roller and establish roller. Graph the 8 assembly that expressed a kind of auxiliary roller concern signal. To receive exact size and form, finally shape second in used fuse. Graph the example of 9 figuration craft graph that are material of window of steel of colour board push-pull. Graph 9 colour board push-pull steel window expects shape craft graph bites buccal structure is window of colour board steel close sectional common form. In shape in the process, 180 character is simple degrees a side uses 4 normally second shape, another side is commonly used 6 second shape. Normally the gear ratio of fluctuation roller is 1.

3:1, the datum diameter of next roller is 140mm.

5, the CAM of roller (CAM) technology colour roller of profile of board door window is the crucial part that profile shapes. The basic characteristic of roller is: Appearance outline is complex and precision is tall, the wearability of roller should satisfy large quantities of requirements that estimate production. Use groovy machining, assure hard model face precision, especially axial precision and be out of shape round horn. This gives debug the job to bring very big workload. CNC Machining is CAD / one of manufacturing segment that beneficial result can produce most in CAM technology, it can assure  the treatment mass that the product reachs extremely tall treatment precision and stability, unit process of cargo bandling implements automation easily, cycle of productivity high production is short,  it and CAD join close together, can define generation to process an instruction from the number of the product, make sure the spare parts has accurate harmonious sex and interchangeability, control appearance and dimension precision strictly. Requirement of precision of more sophisticated treatment exceeds the geometrical figure that produces a boy or girl friend tall, the design is changed more frequent, production lot is smaller, the advantage of CNC Machining gets more easily developing. Afore-mentioned characteristics are agreeing with the production of roller of door window profile. A main task in CNC Machining is numerical control process designing, because different roller range is sophisticated, roller breed is much, process designing workload is big, process designing rate is slow become restrict those who improve productivity " bottleneck " . Use manual process designing according to statistic, of the handling time of the process designing time of a spare parts and machine tool than, it is 30:1 on average about. Accordingly, want to develop the function of numerical control equipment adequately, must use advanced computer automatic process designing, use computer undertakes to program of numerical control machine tool works, have numeric consideration automatically by the computer namely, write sheet of spare parts machine program. Current, cent of automatic process designing is two branch, one is the language type that is a delegate with APT language system of automatic process designing, the geometrical form that it processes a spare parts with statement form description and feed and method taking a knife, vocabulary of language of this kind of system is rich, the geometry of the definition kind look is much, the system is huge, take up memory is old, need to use large computer, cost is high, and master not easily, need technical process designing staff. Another branch is system of process designing of seesaw pattern graph, the development of its have the aid of at computer plot technology, machine the outline of the spare parts with scale of seesaw pattern kind directly, seek solution automatically through what computation and feature nod, output code by definite pattern. This kind of system pursues from the spare parts the emersion of form, of contrail taking a knife generate, the unripe Chengdu that the dynamic imitate that machines a process dictates till CNC Machining is to adopt screen menu drive, seesaw pattern gets the figure, have the good point with figure, intuitionistic, high efficiency; This kind of system still can pass DXF file and data of trade of other plot software, be helpful for realizing CAD / CAM unifinication technology. The NCUT system that northward industry university develops belongs to this kind of system namely, at the same time it still contains treatment to emulate module, but imitate machines a process, replace try cut treatment. This software is a compositive personal computer graph seesaw pattern numerical control is automatic process designing software,  can undertake the automatic process designing of the graphical definition of the spare parts and treatment, after  defined a spare parts when the user and deciding craft parameter; This system will generate numerical control code automatically. Main function includes its function: (1) plot and editor function: Graphical scale: Include a variety of means to define dot, linear, polygonal, contour line (many justice line) , conic curve, analytic curve and batten curve. Command operation of simple,  is convenient, can implement the definition method with graph almost entire plain. The graph edits: Include pair of transition between graphical element (round horn, pour wine cup) , interrupt, clip, form close outline and drawing, delete, go back on one's word etc. The graph revises: Can have a variety of shift to some group of graph, graphs, graph piece, rotate, shrink put, the geometrical processing such as mirror image, copy. Indication processing: Can undertake to the graph local shrink put, be full of the processing such as shift of Quan Bing, mobile camera lens, center. Still can open local window at any time, so that watch overall figure and local figure at the same time, and but hold form all sorts of operations. Measure with inquiry: Measurable all sorts of dimension, distance, angle; Return the graph that can inquire all sorts of graph element and attribute data. Assist an operation: Reseau is caught, diagnostic dot is caught, all sorts of check take the auxiliary and constructive step such as the method. The file governs a function: Include to put store to graphical file, lade, list, retrieve can pass DXF file to exchange graphical data with other system. (Function of process designing of 2) numerical control: Prepare a function: Set knife warehouse: Use at library of cutting tool, knife to manage. Include knife library option, delete, increase, inquire; installs treatment parameter: ? Shaddock does not have inclined to pilfer of Huang of  ostrich sincering feeling silent bad to denounce the appearance that promote  to ask  ? contrail computational function: Free contrail: The definition of seesaw pattern is sharp / turning of outline of; of circular arc machine program: Along one outline grinding of; of mobile cutting tool machines: Produce outline grinding machine program. (3) code generation machines imitate function: Set postposition code kind: The setting produces the code of treatment code; of akin type to output: Output already wove orbit machines code; to machine imitate: To the effective treatment imitate of machine program,  includes to weave to him user the imitate of the program. The code that print: Output code function of process designing of contrail of printer; (4) : Orbit join: The photograph adjacent that uses same cutting tool machines orbit to be linked together,  avoids to return editor of contrail of; of the origin that change a knife: The contrail of cutting parameter; that uses at revising the treatment contrail that already generated deletes: Delete the improper treatment contrail that already existed. Before generating knife heart contrail to there are batten curve or 2 complex curves such as the curve to be in in outline, can be opposite according to the user the requirement that machines disperse precision becomes its disperse multistage circular arc. What be like horny round part in the function that the following convenient users consider in process designing is much go out into how; What the dot that take a knife is in is automatic receive a knife; Very square advantage uses the interference of examination cutting tool of cutting tool group to wait. Use the communication technology of the computer and numerical control machine tool, transmit automatically what implemented numerical control program, shortened the machine tool assists time, reduced code to input a mistake, raised the utilization rate of the machine tool greatly, reduced percent defective. In the past, the input of numerical control program is armrest industry pattern a code piles up the ground to key in, a longer program wants the left and right sides ten minutes, the time photograph with the precision work that completes a part is about the same. Manual input avoids a mistake very hard, and any wrong metropolises create work discard as useless or machine tool accident. The news report that uses the computer and numerical control machine tool accepts ventriloquial method, can send numerical control well and truly the machine tool quickly, raised the utilization rate of the machine tool. Because realized the communication between the computer and numerical control machine tool, a few seconds in the transmission that can realize on 1000 statements. A common disk can store 2, the treatment data of 3000 roller. Make the utilization rate that can raise numerical control machine tool so, right complex model the finish machining of face roller, can raise utilization rate about 40 ～ 50% . Eliminated factitious input error,  reduced waste, effectively prevented the accident that causes as a result of program mistake. Facilitating roller piece of data save. Repeat production and roller piece repair is very convenient. Graph 10 treatment quench the 8 labour digit of roller controls lathe variety roller of board door window should use new cutting to machine craft, realize finish machining of the turning after quenching, improved product precision and product service life greatly thereby, simplified technological process, shortened product development is periodic. Graph 10 it is to use 8 labour digit to accuse lathe treatment to quench roller. Graph the roller of 11 window of door of high accuracy steel that are treatment of numerical control lathe. Graph because the roller of profile of window of door of high accuracy steel that lathe of 11 numerical control machines is right the special requirement of roller performance characteristics, roller should choose harder data to be handled through quenching commonly, its hardness is very tall. In the treatment craft previously, to the roller with precision particularly high demand, leave certain surplus before heat treatment only, grinding craft is used to do precision work again after heat treatment; To the roller with precision particularly not high demand, machine dimension before heat treatment commonly, the method of manual polish is used again after heat treatment, but this kind of method is indelible of heat treatment be out of shape, roller precision especially appearance precision has bigger error, affect a metal thereby shape. As the development of production technology, especially the rapid development of cutting tool material and cutting craft, appeared coating hard alloy, exceed material of hard hard alloy, pottery and porcelain, cubic nitrogen to turn the material of new-style cutting tool such as boron. The occurrence of material of new-style cutting tool improved cutting tool durability and cutting treatment productivity greatly not only, rose to machine precision and exterior quality, and the treatment problem that solved a lot of difficult treatment material, usable turning treatment replaces the grinding that uses before to machine partly, raise tall hardness to quench the cutting of material machines productivity greatly. For this we pass much cutting experimentation and cutting craft parameter to optimize an experiment, chose name of proper cutting tool material, decided the cutting craft parameter in CNC Machining, realized finish machining of the turning after roller quenchs, improved roller precision and roller service life greatly thereby, simplified the technological process that roller makes, shortened the development of new section section and development cycle, reduced manufacturing cost. CNC Milling
