5 × 3200=120000 Mm3/min) . Vf of × of MRR[1]=doc × Woc (Doc: Cutting deepness, woc: Cutting width, vf: Feed speed) . Principle of process designing of 5 axes numerical control [2] is annular milling cutter Σ along S =S (u of parameter curved surface, on V) I (I=1, 2, ... ) P I=S[u(w) of knife contact method, v(w)] does cutting exercise, cut contact to be C =C I currently, j =S [u(wi) , v(wj)](among them J=1, 2, ... ) , knife dot and vector of cutter shaft unit use O I respectively, j and T I, j expresses. In C I, j place is built cut contact local coordinate is (X C - Y C -Zc, LCS) . Because be 5 axes treatment, accordingly cutting tool photograph should have 5 freedom to spend to curved surface, 3 freedom are spent use at making sure cutting tool and curved surface are cut to be nodded at C, two the rest of freedom are spent it is knife dip λ and knife corner ω respectively. In O point point builds cutting tool coordinate is (XT -YT-ZT, TCS) , can calculate through a series of commutation matrix the knife that gives workpiece coordinate to fasten WCS to fall dot data M (X W, YW, ZW, IW, JW, KW) =M (LCS of ← of WCS ← TCS) . CNC Machining emulates a principle (disperse vector law) disperse vector law [3] is the curved surface that will need treatment (or hypostatic) the several foothold that are a few disperse according to constant precision change, replace former curved surface with its, this process is calculated namely the way that each disperse dot handles in former curved surface is measured to arrow, the defines with place point-blank semifinished product border that measures way to arrow from law of this bits of edge or as other as the spare parts surface intersect, the smallest length that point of intersection and the least value that are apart from between disperse dot formerly nod a law to be measured to arrow for this disperse. When emulation computation, the cutting tool that fashions what from this disperse the dot sets out and measure along this Xiang Shi that choose a magic art with cutting tool motion point-blank wraps body of subsidiary channels in the human body through which vital energy to intersect, if point of intersection is less than original law to the distance that disperse nods,Xiang Shi measures length, replace original law to measure length to arrow with nodical distance, withhold original law to be worth to vector length otherwise. Repeat this process to be finished till treatment of cutting tool cutting so, the arrowy value of a quantity that orders through these disperse decreases ceaselessly come the material purify process that imitate emulates body of semifinished product of cutting of the cutting tool in machining a process. Use trigonometry piece or quadrilateral piece the terminal and ordinal join that these semifinished product ways Xiang Shi measures, reframe treatment surface, undertake machining emulation, indication semifinished product and treatment result. Process of 5 axes CNC Machining does not suffer imitate of disperse vector law the limitation of configuration of cutting tool geometry and cutter shaft direction, emulation precision and speed can adjust at will according to computer function, and support OpenGL graph technology completely, do not have special requirement to showing calorie of performance. Milling cutter of applied blame mark undertakes numerical control process designing and treatment are emulated 1 build model of milling cutter maths to be with 7792VXD09WA025Z2R milling cutter exemple, above all YZ datum plane as careless draw plane, z axis square to as cutter shaft direction, build bit outline and paint of grass of cutter hub outline respectively according to bit and cutter hub data, if pursue 1, 2 are shown. YZ axis node is origin of department of coordinate of TCS of department of cutting tool coordinate, if pursue,3 are shown. Nextpage gives the part that shares treatment to name from the extraction in bit and careless draw of cutter hub outline for CUT, the share that extraction gives not to participate in treatment names for NOCUT, if pursue,4 are shown. With these two new careless draw circles Z axis to build two homonymic turn coming back. Process designing of 2 numerical control because outline of curve of point of 7792VX series milling cutter and standard milling cutter are different, value of material remain ply can be compensated in Part parameter when process designing. Principle of 5 axes CNC Machining applies to CATIA V5 likewise 7792VX (big feed) series milling cutter. Surface of the cutting tool when 3 treatment emulate emulation treatment and workpiece surface intersect, CUT part uses excision data, NOCUT part is used detect collision and interference, the new face of the generation after material of work semifinished product is excised reframes by disperse vector law. Last word the article introduced 5 number of axle of CAITA V5 to accuse process designing and treatment to emulate a principle, and combine STELLRAM 7792VX (big feed) the applied example of series milling cutter, elaborated digital-to-analogue of substance of the milling cutter that be not mark to build, note of 5 axes process designing, treatment emulates the content such as the process, these principles and method apply to the milling cutter is not mark of other type likewise.
