ワイヤ放電加工機の制御方法およびワイヤ放電加工機
Document Type and Number:
Japanese Patent JP7390351
Kind Code:
B2
Abstract:
Provided is a wire electric discharge machine (10) which processes a workpiece by applying prescribed pulse power between a traveling wire electrode (16) and the workpiece (17), wherein in the machine: a working liquid is supplied to nozzles (12a, 14a), which jet the working liquid in the traveling direction of the wire electrode, by means of supply pumps (20, 21) by adhering, to the workpiece, the nozzles (12a, 14a); the supply pumps are controlled through constant pressure control for controlling the pressure of the working liquid supplied to the nozzles to a prescribed constant pressure; the frequency of a current is measured, the current being supplied to the supply pumps, which supply the working liquid to the nozzles, by moving the workpiece to the wire electrode in a traverse direction of the traveling direction of the wire electrode; and the supply pump control is switched from the constant pressure control to a constant flow rate control, for supplying the working liquid of a constant flow rate to the nozzles, when the measured frequency exceeds a threshold frequency.
