METHOD FOR MEASURING TILTING ANGLE OF WIRE ELECTRODE IN WIRE ELECTRIC DISCHARGE MACHINE, AND ELECTRIC DISCHARGE MACHINE HAVING DEVICE FOR SETTING TILTING ANGLE OF WIRE ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a measuring jig and a measuring method, by which measuring jig and measuring method, a tilting angle given to a wire electrode can be easily and surely measured in order to improve the accuracy of taper machining in wire electric discharge machining.;SOLUTION: A measuring stand is a rectangular conductive object capable of being horizontally set on an XY table, and is shifted in the horizontal direction perpendicular to one side end surface, and has a pair of feelers elongating perpendicular to a side end surface with different lengths. A vertical wire electrode and a tilted wire electrode tilted by a required angle are brought into contact with a pair of the feelers respectively four times in order from one reference position located outside the portion between a pair of the feelers. The detected coordinates of both electrodes are stored. The measured tilted angle is obtained by calculation from the measured positional coordinate data of the contacts and preliminarily prepared data and programs.;COPYRIGHT: (C)2008,JPO&INPIT
