Investigation of Machining Energy in Wire Electrical Discharge Machining Using Measurement of Deform

This paper aims at investigating the machining energy in wire electrical discharge machining. The open kerf was designed on raw martial block to obverse deform resulted from the discharge machining, and the deform on the material block was measured. The density of energy distribution was different along the kerf, which results in the inhomogeneity deform and ever more frequent breakage of wire. This finding proved the rule which the hole for wire must be drilled before machining must be complied with.
