Title:
放電加工制御方法および放電加工制御装置
Document Type and Number:
Japanese Patent JP3878222
Kind Code:
B2
Abstract:
A detected value indicating a machining state is filtered and a machining gap between an electrode and a workpiece is adjusted by using a control variable obtained through this filtering. Therefore, machining speed can be improved by maintaining a stable machining state through suppression of disturbance to a gap distance control system due to eccentricity of an electrode, due to fluctuations in electric characteristics at feeding brush sections, and due to mechanical resonance of the electrode driving system.
