摘　　要：超大厚度钢锭火焰切割机是为切割大型铸锻件而设计的专用高档数控设备。由于切割过程需要水平匀速运动和钢件外形的不规则等因素对控制割炬行走速度和行走轨迹提出了很高的要求,因此传统的数控运动控制系统不能达到预期效果。针对切割工艺要求,系统基于开放式控制的思想,采用IPC、IMAC运动控制器、激光测距仪和伦茨伺服构建了运动控制系统。采用了速度环和位置环双闭环的控制方式,并通过激光在线测距系统实现了不规则空间曲线的运动控制。The ultra thick flame cutting machine is a special NC equipment designed to cut the heavy casting and forgings.The factors of uniform motion in horizontal direction and the irregular shape of workpieces have higher requirements on wording speed and path of cutting torch. So the traditional control system cannot realize the expected effect.According to the cutting process,the control system was developed with IPC, IMAC motion controller,laser measurement instrument and Lenze servo.Both the speed loop and position loop were used in the motion control, and the online laser measurement system was designed to realize the irregular space trace motion.
