摘　　要：针对目前电火花加工机床数控系统与脉冲电源独立运作、集成性不足的问题,设计了基于台达NC311A的电火花加工机床集成控制系统。采用数控系统本身的插补来实现机床的运动控制,用NC311A上的SOFT模块实现对脉冲电源等的控制。基于FPGA设计了一台直流斩波电源,开发了人机交互界面,实现了电源与机床控制系统的实时通信。重点介绍了台达NC311A上SOFT模块的使用及通信方式、电源的设计方案及实验验证。Aiming at the problem that the NC system and the pulsed power supply operate independently and integratedly,the integrated control system of electro-discharge machines based on Delta NC311A is designed. Using the CNC system itself to achieve the interpolation of the movement of the machine,with NC311A SOFF module on the control pulse power. Based on FPGA,a DC chopper power supply is designed, and the human-machine interface of power supply is developed to realize real-time communication between power supply and machine tool control system. This paper mainly introduces the use of SOFT module on Delta NC311A and the design of communication mode,power supply and related experiment.
