基于规律排列孔数控编程的实验教学∗

摘要

以FANUC 0I数控铣床系统为平台介绍了钻孔固定循环指令格式与参数含义；以常见的规律排列孔为例，研究了子程序、钻孔指令中的K参数、宏程序三种方式的使用场合和编程技巧。实践证明，灵活运用子程序、K参数、宏程序可大大简化编程，加深学生对数控程序优化的认识和理解，提高学生数控编程、数控机床操作的综合能力。%In this paper, the format and the parameters of the drilling fixed cycle instruction are introduced based on the FANUC 0I NC milling system;the application occasion and the programming technique of the three methods which include the subprogram, the K parameters in the drilling instruction and the macroprogram are studied. Practice has proved that flexible use of the subprogram, the K parameters and the macroprogram can greatly simplify programming, deepen students' recognition and comprehension to the NC program optimization of, and improve the students' comprehensive ability of the NC programming and CNC machine tool operation.
