The Effects of Cold and Cryogenic Treatments on the Machinability of Beryllium-CopperAlloy in Electro Discharge Machining
نویسندگان
چکیده
In this study, beryllium-copper alloy was subjected to around -150° F for cold treatment and to around -300° F for cryogenic treatment and the effects of these cold and cryogenic treatments on the machinability of beryllium-copper workpieces in electro discharge machining have been investigated. Experimental results showed about 20-30 % increase in material removal rate of cold and cryogenic treated workipeces. Variations in electrode wear rate, surface roughness and average white layer thickness were found to be marginal.
