针对梯形螺纹如何在数控车床上高速加工的问题,分析其在加工中的主要技术难点,并针对不同尺寸梯形螺纹的加工问题,提出具有可迁移性的宏程序模块设计方法,通过建立加工模型,编写梯形螺纹加工程序模块,并在FANUC数控车床上加工验证完成最终零件加工。通过加工验证表明,通过宏程序模块设计不仅能够解决梯形螺纹在数控车床上的高速加工问题,还可实现在不同梯形螺纹零件上加工时的通用性和可迁移性。同时该加工设计思路具有较强的通用性,可适用于蜗杆和大螺距螺纹的加工。
Aiming at the problem of how trapezoidal threads are machined on CNC lathe at high speed, the main technical difficulties in machining are analyzed. Aiming at the processing problems of trapezoidal thread with different sizes, a design method of macro program module with migratability is put forward. By establishing machining model, Write trapezoidal thread processing program module, and processing in the FANUC CNC lathe to complete the final part processing. The machining verification shows that the design of macro program module can not only solve the problem of high speed machining of trapezoidal thread on CNC lathe, but also realize the versatility and transferability when machining different trapezoidal thread parts. At the same time, the processing design ideas have strong versatility and can be applied to the processing of the worm and the large pitch thread.
