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 comparison is stable; But, the cutter that the company produces abroad is also that the standard makes an experiment with their material; The treating being recommended by is suitable to their standard comparatively like the parameter , material quality has the certain difference with domestic part , this difference shows comparatively obviously , some parameters can apply directly, but some effect dispatches right away comparatively 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 company standard and.
The technology selecting and using the domestic cutter , seldom having the bright metal recommending high speed to chop parametric , is necessary making an experiment, get the comparatively 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, quick-cutting 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 corner 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;
2) tries one'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;
3) constant each edge feed , improve the quality, prolongs cutter life-span;
4) outline treating are kept waiting in level surface.
Quick-cutting CAM software:
Several years ago will have started quick-cutting processing programming technology research, the Delcam company , has developed the quick-cutting automation programming software module; Lately, the MasterCAM company has also developed the quick-cutting automation programming software module; You also are in in the homeland north navigation developing the quick-cutting automation programming software module;
Six, high-speed machine tool numerical control system characteristic
1) high speed data is processed
2) corner forecasts are handled
