ABSTRACT:
A numerically controlled wire-cutting electric discharge machine composed of a numerical control apparatus controlling a feeding of a piece of work on at least three axes and a wire-cutting electric discharge apparatus. The wire-cutting discharge apparatus comprises a pair of V type slot guides which stretch a wire therebetween, a first and a second drive means which displace the work in the direction of two axes with respect to the wire electrode and a third drive means which rotates at least one of the V type slot guides around a predetermined axis, so that the relative displacement between the piece of work and the wire electrode is controlled via the first and second drive means by two outputs of the numerical control apparatus, the V type slot guide is rotated via the third drive means by another output of the numerical control apparatus so that the V type slot guide is turned a predetermined angle in the direction of the above-mentioned relative displacement.
