METHOD AND INSTRUMENT FOR DETERMINING POSITION WHERE WIRE ELECTRODE IS IN CONTACT WITH WORKPIECE |
摘要 |
<p>A contact position measurement method comprising moving either a wire-shaped tool electrode or a workpiece relative to the other within a plane, and causing the wire to approach a reference position on the workpiece; applying a voltage between the wire and the workpiece with the wire oriented perpendicular to the plane; detecting contact between the workpiece reference position and the wire; placing the workpiece reference position generally at the center of vibration of the wire, determined in accordance with the number of occurrences of detected contact; generating coordinate data indicating the position of the wire with respect to the workpiece; and determining the position of contact based on the coordinate data. <IMAGE></p> |
