摘要:
采用工业计算机和运动控制卡等硬件构建开放式数控火焰切割系统,以Visual Basic 6.0为开发工具,开发了提高异形工件火焰切割过程平稳性的系统控制软件. 采用激光位移传感器对被加工件进行非接触式扫描,获取工件在加工路径上的高度信息,并以此为依据进行切割轨迹的规划和高度补偿. 试运行结果表明,当工件表面高度发生变化时,由伺服系统进行三轴直线插补或三轴螺旋插补,能够在切割过程中使割炬与工件表面之间的距离始终保持一致,位置精度±0.02 mm,重复定位精度±0.05 mm. 整个系统保证了良好的切割质量,达到了切割过程平稳高效的目的.
Abstract:
We built an open numerical?control?flame cutting system for improving the stability of special?shaped workpiece cutting processing by using industrial computer and motion control card as hardware,and Visual Basic 6.0 as control software. The?height information of workpiece surface along cutting path through non?contact measurement was obtained by using a laser displacement sensor, by which the cutting path planning and altitude compensation could be performed. The trial operation results indicate that, when the surface height of workpiece changes in processing, the distance between the cutting torch and the workpiece surface could be kept almost the same through three axis linear and spiral interpolation, and the positional accuracy is about ±0.02 mm and the repeat positioning accuracy is about ±0.05 mm. The whole system could ensure a better cutting quality, realizing a smooth and efficient cutting process.
