摘　　要：螺纹切削复合循环指令与单一和固定螺纹指令相比,系统能够进行内部逻辑计算,无论多大的螺距,只需编写一、二段程序或在循环指令中输入相关数据,就能够生成程序,程序占用内存少,具有开放性和灵活性,且易于修改的特点。通过对不同数控系统的螺纹切削复合指令在加工螺纹的应用比较,分别指出其存在的差异。设想了能够加工普通螺纹、大导程螺纹、多线螺纹、异型螺纹、蜗杆的新型螺纹切削循环指令,以弥补原有指令存在的不足,满足加工的需求。Compared thread cutting composite cycle instruction with single and fixed screw thread instruction,systems can perform internal logic calculation,no matter how big pitch,only need to write one,two section of a program or input related data in the cycle instruction,will be able to generate procedures,program occupy less memory,openness and flexibility,and easy to modify. Through the different commands in the processing of numerical control system thread cutting composite threaded applications,respectively, points out its differences. Envisioned ordinary processing thread,big lead line,a new type of thread cutting,heterotypic screw,worm cycle instruction,to make up for the deficiency existing in the original instruction,meet the needs of processing.
