Effect of Pulse on / Pulse off on Machining of Steel Using Cryogenic Treated Copper Electrode
نویسنده
چکیده
-Electrical discharge machining (EDM) process, at present is still an experience process, wherein selected parameters are often far from the optimum, and at the same time selecting optimization parameters is costly and time consuming. In this paper cryogenic treatment is used for increasing the material removal rate and lowering the tool wear rate. cryogenic treatment is a process of keeping the specimen in cold environment to increase its wear resistance and relieving its residual stresses. In the present paper study conduct on MRR and TWR by using cryogenic and non cryogenic electrode with pulse on/off as parameter.
