摘　　要：双轴工作台目前应用广泛,对其的控制是实现二维平面轮廓的关键。双轴工作台中X、Y两路步进电机由PLC控制,步进电机上的齿轮齿条机构将旋转运动转换为平台的直线运动,通过X、Y的运动组合完成自动打箔轨迹。文章详细叙述了工作台系统的组成原理、控制方案及相关硬件,并利用直线插补原理编写PLC程序,实现了工作台的圆弧轨迹。通过设备空载实验的模拟,取得了良好的效果。Control of the work bench is a key point in realizing 2D space contour. The curve path was completed automatically by the movement combination of X and Y step motor, which controlled by S7-200 PLC with two gear rack mechanisms converted the rotary motion into linear motion. The method was described in detail, including system combination principle, software solutions and hardware. It applied linear interpolation to write PLC control program, and realized circular path. The no-load test simulation showed good results.
