嵌入式电火花线切割加工数控系统原型

摘要

This paper presents a prototype of embedded WEDM-CNC system based on ARM microprocessor and Linux kernel. The ARM developing board is used as the host computer of the CNC system, providing the functions of user interface and data processing. An MCU is used as the slave unit of the system, performs the I/O control and the motion control of step motors. Cooperating with the Android platform, a remote monitor system is established, on which the status of the machine tools is displayed remotely.%提出了一种采用ARM微处理器和嵌入式Linux内核作为系统平台的嵌入式电火花线切割数控系统原型.ARM开发板作为CNC系统的主机,提供用户界面和数据处理功能.MCU作为系统的从动装置,执行I/O控制和步进电机运动控制.与Android平台协作,建立了一个远程监测系统,可随时监视机床的加工状态.
