通过对链轮几何特性与精度的分析,结合数控系统的功能,研究了链轮的数控加工技术。系统地介绍了链轮的数控加工方法,重点阐述了齿廓数控加工的子程序编程与变量编程;2种方法编制的程序简练,调试运行方便,加工质量好、效率高,无需专业软件及专用刀具,易于掌握推广。
Through the analysis of the geometric characteristics and accuracy of sprocket, combined with the function of numerical control system, the numerical control processing technology of sprocket is studied. This paper systematically introduces the CNC machining method of sprocket and focuses on the subroutine programming and variable programming of tooth profile CNC machining. The programs compiled by the two methods are concise, the debugging and running are convenient, the processing quality is good, the efficiency is high, no special software and special Knife, easy to grasp promotion.
