A related parameter can be given in the main program, and then call the subprogram like a fixed cycle to finish the trapezoid thread's machining program.

这样就可以像固定循环一样，在主程序中给定相应的参数，然后调用子程序，就可完成相应的梯形螺纹加工程序的编写。

The simulation result shows that compared with fixed-cycle and full-actuated control methods, it has a more extensive application range, and possesses the stronger self-adaptive competence.

仿真结果表明，该模型比传统定时和感应式控制的适用范围更大，自适应能力也更强。
