摘　　要：根据定位销零件具有尺寸相近、形状相似的特点,将多组定位销整合为零件族。通过分析定位销零件族的尺寸特点,绘制定位销零件族的参数化图纸。利用FANUC系统的用户宏程序可进行参数化编程的优势,通过改变宏变量的值,调整程序中的各项加工参数便能实现不同尺寸定位销零件的加工的特点,探讨定位销零件族参数化程序的编制方法。在主程序中用G65指令多次调用多组定位销零件数据,编制定位销零件族加工程序。经HT200X560数控车削中心验证,编制的程序通过改变定位销的尺寸数据,即可达到加工定位销零件族零件的目的,也可加工出满足尺寸要求的合格产品。通过这种方法加工定位销零件族,可达到减少编程时间、提高数控机床生产效率、实现加工标准化的目的。此设计思路也可移植到其他的零件族程序的编制中。According to the characteristics of similar size and shape of locating pin parts,multiple groups of locating pins were integrated into part family.By analyzing the dimensional characteristics of locating pin part family,the parametric drawing of locating pin part family was drawn.Using the advantage that the user macro program of FANUC system could carry out parametric programming,the machining characteristics of positioning pin parts with different sizes could be realized by changing the value of macro variables and adjusting various machining parameters in the program.The programming method of parametric program of positioning pin part family was discussed.In the main program,G65 command was used to call multiple groups of positioning pin part data,and the processing program of positioning pin part family was compiled.Verified by HT200X560 CNC turning center,the program could achieve the purpose of machining locating pin part family parts by changing the dimensional data of locating pin,and could also process qualified products that meet the dimensional requirements.By machining the positioning pin part family through the program,the programming time can be reduced,the production efficiency of NC machine tool can be improved,and the purpose of machining standardization can be realized.The design idea can also be transplanted to the programming of other part families.
