High-Speed Jump Motion Control System for Electro-Discharge Machining Based on Programmable Multi-axis Controller

Abstract

Abstract: The requirements from designing high-speed jump motion control system for EDM (electro-discharge machining) were suggested in three terms: system capable of achieving high-speed motion control, system with good performance in responding and following the reference signal for axis and a jump motion course with high acceleration. A high-speed jump motion control system for EDM based on programmable multi-axis controller (PMAC) was studied and designed to meet the requirements suggested. The control system proposed was applied to type DK7140 commercial EDM machine and achieved stable main axis jump motion with maximum speed of 200 mm/s and maximum acceleration approximate to 9.68 m/s2. Through the experiments of processing narrow slots, the control system obtains good results in terms of maximum machined depth and processing efficiency, and validates the good performance in control and machining.
