The demand that high speed milling machines logarithm to control process designing system is higher and higher, the high speed with high price machined equipment to raise higher security and effectiveness requirement to software. High speed cutting is having more special than traditional cutting craft demand, besides wanting to have machine tool of high speed cutting and cutting tool of high speed cutting, having software of appropriate CAM process designing also is crucial. The numerical control instruction of CNC Machining included all process, a system of excellent process designing of CAM of high speed treatment should have very high computation rate, stronger interpolation function, whole journey to cut examination and processing capability, automatic knife handle and clamping apparatus automatically to interfere rate of examination, feed to optimize processing too function, need treatment contrail of orbit monitoring function, cutting tool. Process designing of high speed cutting should notice to machine methodological security and effectiveness above all; Next, want all likelihoods to make sure cutting tool contrail is smooth and smooth, this can immediate impact machines the life of the spare parts such as quality and machine tool main shaft; Finally, want to make cutting tool load even as far as possible, this meeting affects the life of cutting tool directly. (1)CAM system should have very tall consideration use in treatment of high speed of process designing speed very small cut quantity and cut deep, program of more traditional than be opposite CNC Machining wants the NC order that reason high speed processes to be gotten greatly much, consequently requirement computation speed wants fast, want editor of contrail of convenient and managing cutting tool, optimize the time of process designing. (2) whole journey has been prevented automatically cut processing capability and interference of automatic knife handle to check treatment of ability high speed to machine the cutting speed of nearly 10 times to undertake machining with the tradition, once had happened to cut pair of machine tools, product and cutting tool to will produce disastrous consequence, ask its CAM system must have whole journey to had prevented the capacity that cuts processing automatically so. One of main features that high speed machines can use the cutting tool of lesser diameter namely, machine the detail structure of the mould. The system can hint the briefest clip runs cutting tool length automatically, undertake cutting tool interferes an examination automatically. (High speed machines the strategy of contrail of cutting tool of high speed cutting with rich 3) to walk along knife means to having special demand than traditional pattern function to machining craft, consequently requirement CAM system can satisfy these specific craft requirements. To can ensure the biggest cutting efficiency, assure the security that machines when high speed cutting again, CAM system should the size according to treatment instantaneous surplus, undertake automatically optimizing handling to feed rate, in order to ensure cutting tool of high speed treatment gets the smooth stability of power position, improve the service life of cutting tool. CAM software is in generate respect of cutting tool contrail to should have the following function: ☆ should avoid the abrupt change that knife way takes in cutting tool contrail, lest because of local the damage that be cut too and causes cutting tool or equipment; What ☆ should maintain cutting tool contrail is smooth, avoid to be quickened suddenly or decelerate; ☆ leaves a sword or excessive part had better use the knife below inclined between travel or circular arc leaves a sword, avoid perpendicular next knives are close to workpiece material directly; The end points that cuts all right uses circular arc connection, avoid linear join; ☆ incomplete surplus is machined or clear root treatment is the important step that improves treatment efficiency, should use treatment for many times commonly or use series cutting tool from arrive small minutes greatly second treatment, avoid to be machined with the penknife finish, still should avoid main wide cutting; It is very important that editor of contrail of ☆ cutting tool optimizes a function, avoid redundant sky knife, the mirror that can pass pair of cutting tool contrail, duplicate, rotate wait for an operation, avoid to repeat calculation; Contrail of ☆ cutting tool cuts out repair function is very main also, can reduce empty knife through cutting out accurately, improve efficiency, also can use at a zero process designing when local change, need to revise metabolic part only right now, need not be opposite whole model new-model; ☆ can provide outstanding visible emulation treatment imitate and cut an examination too, if Vericut software can detect well,interfere.
