Module of CAM of cut of Delcam FeatureCAM central line - characteristic of FeatureWIRE process designing is to be based on a feature, be based on the knowledge, complete function line that uses automatic feature to identify a technology system of cut CAM process designing. Leave other to going up model we need not resemble treatment workpiece again normally process designing technology, preexistence is three-dimensional CAD builds a model, undertake process designing again, the fluctuation that FerureWIRE needs work of fluctuation different treatment only curve of CAD of 2 dimension plane is OK, ferureWIRE needs set to machine craft only, machine a condition, machine attrib border condition, ferureWIRE will match fluctuation curve automatically, make treatment way automatically next, undertake emulation imitate finally, handle a program to generate treatment code according to postposition of different machine tool at the same time, can undertake CNC is machined next. 3, technological process of Delcam FeatueWIRE process designing and treatment combine mould of nose of plastic different profile to machine technological process of process designing of example introduction Delcam FeatueWIRE below example introduction. If plan institute is shown,be mould of nose of layering of double Bo of plastic different profile projection drawing of curve of face of peace of three-dimensional and hypostatic model, three-dimensional graph. When using FeatureWIR to process work normally, we need to know the coping curve of three-dimensional different body and bottom curve are OK only, do not need to make the curve three-dimensional and hypostatic model, coping curve and bottom curve can press real work height to distributing in three dimensional space, also can distributing in on a plane 2 dimension. Specific treatment move is as follows: 1, the model is built in FeatureCAMF, the choice machines module, choice Wire EDM machines module here, at the same time the choice measures an unit to be millimeter. 2, the input processes data, processing data can be a curve, also can be curved surface hypostatic perhaps. Need inputs curvilinear data here, curvilinear data can use tripartite software to make, repass data interface guides treatment regards as the curve in FeatureWIRE, the data type that can input is shown like plan institute; The geometrical body in guiding the data type of FeatureCAM also can use FeatureWIRE is tectonic implement generate treatment curve, OK and collective scale is in treatment curve to go up in same plane, when undertaking FeatureWIRE process designing so, the treatment curve that machines curve and bottom treatment curve to will be located in same plane to go up through choosing coping parts direction of edge Z axis is umbriferous to UV treatment plane and XY machine plane to go up, UV of operation of ply of repass set workpiece machines plane to machine planar opposite distance at XY relatively, locate thereby the relative position of coping curve and coping curve; Also can part coping curve and bottom curve scale machines plane and XY treatment plane to go up in UV. FeatureWIRE geometry body is tectonic implement 3, set processes semifinished product, according to the treatment data of the input, choose a ground dimension of preform configuration of spare parts dimension, featureWIRE is OK and automatic calculate according to machining the dimension of workpiece the size of dimension of optimal semifinished product, also can adjust semifinished product dimension according to machining need actually. 4, build new feature concrete move is as follows: (1) the treatment data that the basis inputs and treatment craft requirement, the choice processes specific treatment type, the according to double Bo layering curve data in this example and treatment ask, should choose feature of 4 axes force plug to machine; (2) choice coping machines a curve, if machine a curve to be by scale on same plane, this option will decide a which curvilinear general along Z axis by umbriferous go up to UV treatment plane, if the curve is machined respectively by scale in XY,plane and UV machine plane to go up, direct choice is located in UV to machine the curve on plane to regard coping as the curve. (3) choice bottom machines a curve, if machine a curve to be by scale on same plane, this option will decide a which curvilinear general along Z axis by umbriferous go up to XY treatment plane, if the curve is machined respectively by scale in XY,plane and UV machine plane to go up, direct choice is located in XY to machine the curve on plane to regard bottom ministry as the curve. (4) set slants from position of coping curve Z buy, look of work of fixed position treatment is fastened in the position on Z axis direction to machine tool coordinate. (5) set treatment work is real ply, at that time coping treatment curve and bottom treatment curve are met the ply value according to set parts automatically along Z axis direction by umbriferous to UV treatment plane and XY machine plane; (6) set is worn silk is nodded and cut cut, according to real work the position that wear silk defines the point that wear silk, the choice is optimal cut cut a position. (7) the curve that undertakes coping machines curve and coping treatment curve matchs, detail adjusts treatment method. (8) choice treatment strategy and electrode silk slant put option, these are installed even if set machines craft specificly, machine condition and treatment border condition; (9) affirm in front the treatment craft condition of set and treatment are politic; (10) generation processes cutting data, include cooling requirement, feed, compensation; (11) certain treatment process and treatment craft; (12) click the option that finish, generation machines work way and treatment craft watch to be occupied oddly, these data can be mixed according to specific treatment requirement treatment data undertakes adjustment. (13) the postposition transaction file that chooses correspondence according to particular numerical control machine tool and numerical control system, can change treatment way into the code of machine tool NC that the machine tool can implement so; (14) emulation imitate treatment, OK and intuitionistic observation machines process and the validity that machine method; (15) treatment examines as a result, whether does the work that can observe treatment hind so satisfy treatment requirement. (16) the postposition that chooses before the basis handles an order, generate NC code, machine program is as follows: Machine program of layering of %(double Bo) N10 G92 X0.
