WIRE ELECTRICAL DISCHARGE MACHINE WHICH CORRECTS MACHINING PATH IN CORNER PORTION

摘要

In a corner portion formed at an intersection of a first block to be machined first and a second block to be machined second, an end point of the first block is extended. Then, after moving from the first block to the extended end point of the first block, a wire electrode of an electrical discharge machine returns to an end point of the original block (an end point of the original first block and a start point of the original second block) therefrom along the same path as before, and machines the second block therefrom.

主权项

1. A wire electrical discharge machine adapted to create a machining path based on an axis movement command from a machining program and perform machining by moving a wire electrode and a workpiece relative to each other according to the created machining path, the wire electrical discharge machine comprising
a machining path correction unit adapted to correct the machining path such that in a corner portion formed at an intersection of two consecutive movement blocks in the created machining path, the two consecutive movement blocks being a first block to be machined first and a second block to be machined second, a corrected path will be generated by extending an end point of the first block, that when an extended block end point is reached by moving along the corrected path, a machining path which returns to the end point of the original block along the corrected path will be newly created, and that the second block will be machined by continuing from the newly created machining path.
