Abstract

PURPOSE:To improve machining precision and efficiency by a method wherein a relatively high machining speed is applied in the early stage of the second cutting machining, and the electric discharge machining is conducted at such a machining speed as to obtain a predetermined surface roughness in the final stage. CONSTITUTION:When a rough machining which is the first cutting machining is finished at A, a cutting surface 12 of the work 30 is apart from a design dimension surface 10 at a distance of SIGMAepsilon(I, J). Then the machining by electric energy E(1) in relation to the thickness t(J) of the work 30 is selected by a computer 56, an offset amount suitable for the machining width epsilon(I, J) is determined and the first- round second cutting is conducted under these conditions. A muchining width epsilon(2, J) for the machining by electric energy E(2) is selected by the computer 56, an offset amount suitable for the machining width (2, J) is determined and the second-round second cutting is conducted.
