摘要
针对铺带机控制的特殊要求——铺带头主运动与超声切割运动子系统间的实时联动协调,采用可编程多轴控制器PMAC的随动模式与时基控制方式将两者的运动有机衔接,搭建了铺带专用开放式数控系统。系统以PMAC运动控制卡为核心、以工控机为上位机,且与多数字I/O板卡并行控制,很好的完成了铺带运动控制定位及预浸带随动切割,精度就可满足实用要求。
According to the special requirement of the CNC system for Automated Tape Laying （ATL）, i.e. the synchronized movement between the main system of tape laying head and its sub-system for ultrasonic tape-cutting, tracking-control method and time-based mode from the Programmable Multi-axes Controller （PMAC） applied for dif- ferent cases are described in this paper. With the upper CPU of industrial computer, PMAC is set for motion control as well as Programmable Numerical Controller for on-off control, which fulfills the required functions such as higher precision for machine position control and tracking control of tape-cutting.
