Dual-axis drive technology has been widely applied to large or heavy gantry CNC machine tools,however synchronization performance plays an important role in the precision and safety of machine tools.In this paper,an independent synchronous control card was proposed based on DSP + FPGA hardware architecture for widely used CNC system with pulsed interface,and its software and hardware were designed and developed.The dual-axis drive synchronous control experimental platform with pulsed interface was established,and experiment results show that the synchronous control card can effectively improve synchronization performance between the parallel dual-axis.
