[summary] mirror instruction is one of more significant statements in the treatment of machining center, apply very extensive; Found group of output CL data; Quick, convenient. Basically be opposite in article the output of the treatment of electrode of 260 connecting rod and program undertakes expatiatory. The mirror dictates the calculation that can reduce symmetrical forging electrode to machine is measured, shorten the time that the program exports; When outputting CL data, found the group is OK shorten the length of the program, many programs can finish output, those who decrease to handle single order respectively is trival, the workload of the person that reduce process designing and handlers. 1. The process designing of electrode of 260 connecting rod and processing 260 connecting rod is a bigger symmetrical forging, when machining electrode normally, press following craft to carry out: Mill of essence of → of whole of thick mill of → of the outline outside mill antrum makes bodily form pitch, the data bulk of mill of such essence of life antrum is quite great (make an appointment with 8000KB) ; In addition lever ministry and big, small head transfer partial round part is minor. To make sure dimension asks, do not waste the handling time outside roundlet horn, here introduces a few clever methods. (1) mirror instruction uses 260 connecting rod mediumly in 260 connecting rod is the forging about X axial symmetry (1) seeing a picture, mill outline and model antrum can dictate with the mirror. It is boundary with axial center, 260 connecting rod cent is two parts, weave only half electrode program (orbit mill, thick mill and mill of essence of life weave half) can. Operate the program of half electrode normally first on machining center; When machining electrode of other in part, in sheet of filling entree of origin of the v on machining center, this is to be on Y axis mirror, need to hit the mirror pane of Y axis correspondence only " X " , run this program again, machine an electrode of other in part well and truly, reduced the computation of whole process and transmission time greatly. To some machining center, but direct v axis sets bill of fare (Axis Setup Menu) , click " Y ← → - Y " , realize the mirror on Y axis thereby. (2) founds group of output CL data the round role of the lever ministry of 260 connecting rod and part of big, small join is minor, have R3 ～ R4mm only, if use the knife with bigger diameter to machine whole antrum, short of requirement, partial treatment is redundant besides roundlet horn, extended handling time. If the graph is shown 2 times, we are with axial the center is dividing line in practice, transfer lever ministry and big head place make range of a ditty (include roundlet horn) , call local 1; Transfer lever ministry and small head place make another Xiaoqu range (include roundlet horn) , call local 2; The side outside big head makes range of a ditty (include roundlet horn) , call local 3. After independent curved surface has been done, run the program of face of these 3 ditty respectively, the data of every curved surface is very little, the program has 600 ～ 900KB only, very quick treatment is over. When outputting CL data at the same time, application is founded group (Selec Set) , the machine program of 3 curved surface regards choice above as a working group, output data. 3 separate orders became a whole process, need to be handled to this program only, leave out repeats working time twice, handlers transmits the order to the machine tool, also need to finish only, satisfied dimension to asked to improve work efficiency again already. When 3 intermediate zone that machine electrode of other in part, need to be on Y axis only mirror (apply the methodological) in front. (260 connecting rod use 3) result this kind of method machines electrode, OK and economic regular method machines the time of electrode half, shorten the time of process designing, reduce the computational amount of process designing, improve work efficiency, also can promote the treatment of handlers the standard at the same time. 2. Epilogue mirror instruction can be in Y axis (around semmetry forging) aspirant travel, also can be in X axis (or so symmetrical forging) aspirant travel, so the mirror dictates the application in machining center should get popularizing. Local our process designing sees the symmetrical forging that has roundlet part constantly, press the position of roundlet horn, make it many local face group (include roundlet horn) , output the program of every face group respectively, found properly group appear very important, so do what can decrease to handle small order every time is trival, also can avoid a program much and make operator misapplication, what still can reduce cutting tool bedding face to accumulate milling to cause is serious wear away. Choose reasonably and use these two kinds of methods, can simplify electrode machines craft, improve treatment efficiency, prolong cutting tool life, increasing application arrives actual in, popularizing this craft at present.
