Research of Servo System for WEDM Based on DSP
WEDM as a special processing method is widely used in the manufacturing. Focused on the hardware and control strategy of servo control system deficiencies, a new design plan is proposed for WEDM servo control system based on DSP. Author takes TMS320LF2407A DSP chip as core processor for the system, development of the servo feed control system. In the designing, depend on detection circuit output signal which reflect discharge gap state load, the normal spark discharge and short circuit, and be processed by the corresponding module of DSP, the principle is that get the best spark rate.
