Study on Key Technique of Reconfigurable CNC System

Abstract:

FPGA has been used in CNC system, it can achieve the impulse, the count, arithmetical operation, I/O interface and so on, and therefore it can greatly simplify the design of control circuit. In this special structure mechanism, the processing and monitoring of CNC system based on FPGA instead of traditional MCU is implemented. The overall structure of reconfigurable CNC system is described, meanwhile, the DDA accurate interpolation and the control circuit of stepper motor is emphatically solved through Using the FPGA. With the result of several experiments, the performance of the CNC system is improved, reconfiguration is strengthened, besides, the peripheral interface devices and cost is greatly reduced.
