摘　　要：针对轴形零件实际焊接加工中遇到的困难,利用现场总线、串口通信和GALIL运动控制卡实现了上位计算机对激光器、机器人以及旋转台等系统的同步控制,提出了集成化激光制造系统的多种控制工艺焊接方法.对轴形零件进行了各种激光焊接控制工艺的实验研究,证明了此控制系统可实现多种焊接控制工艺,可以满足轴形零件激光焊接中变速度、变功率、偏角度等各种工艺条件焊接的需求,为轴形零件实际激光焊接中遇到的焊接过程不稳定、首尾衔接处凹坑缺陷等难题的解决提供了新的方法.编程采用VC++面向对象工具加以实现.To solve the difficulties in laser welding cylinder, laser system, robot system and rotary machine system are controlled synchronously by means of PROFIBUS-DP field-bus, GALIL movement controller card and COMM techniques. A novel method of multifunetional control laser welding for integrated laser manufacturing systems is presented. Experiments based on this method were carried out and the results proved that the multifunetional control laser welding could meet the demands of practical applications, such as speed changing, power changing and angle deflexion. And problems of laser welding cylinder, such as welding instability and pits appeared at the end of welding, were solved. Programming is realized by VC＋＋ object-oriented tools.
