摘要
研究在西门子数控立车上加工多头梯形左旋内螺纹的加工程序,既能够保证螺纹的加工精度,又可减少刀具重磨和定位次数,缩短辅助时间,提高生产效率。
The text researches the machining programme of machining steep-le ad multiple-trapeziform left-hand internal screw thread , by using the machining method , The method not only guarantees the machining precision, but also reduc es the times of the cutter regrinding and reorientation, reduces accessorial tim e, and improves production efficiency.
