- Abstract
Aiming at the compatibility and discharge requirements of desktop EDM machine tool numerical control system, a hardware platform of EDM machine tool numerical control system based on ARM and FPGA was designed. The task distribution of the platform was uniform and reasonable, with ARM as the core to build the upper computer, and the transplantation of Linux system to carry out multi-task processing, man-machine interface and interpolation operation. The lower computer system based on FPGA was responsible for motion control, discharge pulse control, auxiliary module control and other tasks. The hardware platform was built in the form of core board plus base board and the communication was carried out by Ethernet port. The experimental results show that the CNC system built by the hardware platform can accomplish the EDM small hole machining. This research provides a hardware platform design of EDM machine tool numerical control system with good portability, low cost of iterative upgrade and adaptability to various pulse power sources.
