基于PLC的数控铣床控制系统的设计

Design of a PLC-based NC Milling Machine Control System

文中介绍了一种基于PLC的数控铣床控制系统,该系统利用PLC丰富的脉冲控制指令实现对数控铣床各轴的步进电机的速度和位置控制,数控加工指令由PC机经串口通信传送给PLC,控制PLC的脉冲控制指令参数,实现加工控制。通过在实验平台上测试,验证了控制系统的可靠性。

In this system, a PLC-based NC milling machine control system is designed. all the axes of the machine are drived by steeper motors, and the motion of motors is controlled by PLC. The speed control and position control of the steeper motor is easy to be implemented by the impulse commands provided by PLC. The NC process compiled on a PC is transmitted to PLC via serial Communications to adjust the parameters of impulse commands. The feasibility of the system is verified by an experimental NC milling machine...
