摘　　要：对相贯线焊接坡口成型加工的参量方程进行建模分析。介绍目前数控切管机设备中使用的两种不同结构类型的割炬支架。针对相贯线焊接坡口的加工,对这两种割炬支架的运动控制方式、实际加工操作以及性能进行分析、比较。同时对实际加工中所涉及的割炬火焰半径补偿进行建模,并通过编程仿真单件图来验证其结果。The parametric equations of processing intersecting curve and welding groove are established and analysed. Two types of torch carriage with different structure commonly used in present NC pipe cutting machine are introduced. According to the machining of the intersecting curve and welding groove angle, the motion control mode, manufacturing operation and the performance are anylyzed and compared. The mathematics model of torch fire radius compensation invloved in the actual processing is also presented, and the single- piece graph simulated by programming is presented to test the mathematics model.
