ABSTRACT:
A method and apparatus for electric-discharge machining a turbine blade are provided. The method includes the steps of: a) preparing a disc material divided into an first portion and a second portion on a basis of a symmetrical line, b) fixing the disc material, with the first portion facing upward, c) forming an initial profile of at least one of the plurality of blades at the first portion of the disc material using at least two roughing tool electrodes to concurrently form a roughing space at the first portion, d) leading at least two finishing tool electrodes into the roughing space to concurrently perform precise machining of the blade, e) turning over the disc material, fixing the disc material and repeating steps c) and d) on the second portion.
