【正文】 4 Be short of the quickcutting automation programming software。 3) Be short of the quickcutting data base or the handbook， is still blank space at present。 4) supporting technology and equipment are fairly inplete 2 cutters: 1) domestic cutter is not able to adapt to the quickcutting application , high speed cuts only entire treating especially stiffly. Entrance cutter price is high. The cutter technology is to affect quickcutting processing a key factor of mould. 2) supporting technologies are not enough to include hilt， online dynamic balance in plete set etc.. 3 high speed moulds process the technology and the experiment 1) Be short of the accumulation applying experience since high speed processes the mould history paratively shortly。 3) Under the machine tool high speed， the dynamic behaviour studies the function being not enough to affect a plete machine as a result,。 2) Intensity that the bit links。 You also are in in the homeland north navigation developing the quickcutting automation programming software module。 4) outline treating are kept waiting in level surface. Quickcutting CAM software: Several years ago will have started quickcutting processing programming technology research, the Delcam pany , has developed the quickcutting automation programming software module。s best to avoid external feed of workpiece and enter next depth return knife motion， direct from the outline. Or adopt a helical line or being sure enter slanting to moving forward。 The treating being remended by is suitable to their standard paratively like the parameter， material quality has the certain difference with domestic part， this difference shows paratively obviously， some parameters can apply directly， but some effect dispatches right away paratively during the period of high speed bright metal chops if using their cutter. But select and use part material quality in the homeland like enterprise having the certain standard, what be put into use part material, can use the part material quality that high speed processes especially， the general meeting is limited in some part material range inner, that this applies the high speed processing technology to us has also provided advantageous condition， has been able to apply to less treating material within range. Being needing to emphasize that here, must choose the treating technological parameter optimizing out a set of capital suitable enterprise on these material， is brought into pany standard and. The technology selecting and using the domestic cutter， seldom having the bright metal remending high speed to chop parametric， is necessary making an experiment, get the paratively satisfied parameter， produce a manufacturer had better to select and use the fixed cutter， cut down the number of times testing that， the standard forming a processing technology, such can improve effective utilization ratio of equipment，lowers production costs， can get the fairly good economic effect. Five， quickcutting route processing a cutter and programming 1) flat surface feeds the route choice 2) outlines process the route choice 3) Keep cutting loading stable 4) keeps relatively stable moving forward giving amounts and feed speed 5) keeps the garden er in flat surface cutting 6) chooses the finish machining margin rationally Programming demand of HSC finish machining to CAM: 1) the bright metal avoiding a corner to the full cuts motion。 4 current cutter enterprise has already done many jobs in the field of the technology resolving the quickcutting cutter， serving facing the cutter processing may help to solve much problem， the cutter has produced a manufacturer being the main body， the reference cutter has produced the technology parameter that the manufacturer provides. Four, improve quickcutting mould efficiency technology 1 cutter diameter and the length choice 2 HSM and the EDM choice 3 does cutting and the lubricating cooling 4 feeds choice: Move forward generally giving amounts〈 milling cutter diameters 10%， move forward giving a width〈 milling cutter diameter 40%. According to material, condition chooses the parameter processing handicraft rationally High speed bright metal cuts the mass processing part material abroad fairly good, material quality level is identical , the treating function parison is stable。s cuts mould finish machining stiffly. Delcam adopt mm diameter cutter to process the narrow slot， rotation rate 40000 rpm , mm depth， feed speed 30 m/min. 1 chooses the cutter parameter， the cutte
