摘　　要：在葫芦的数控加工中,由于葫芦外轮廓的凸凹变化,使用G71粗车复合循环加工指令具有局限性;而实践教学中的毛坯多为棒料,使用G73指令又会产生过多的空走刀现象,基于这两者之间的矛盾,将教材中很少提到的G71Ⅱ型循环加工指令应用于实际教学实践中,既能解决零件外轮廓加工时凸凹变化的问题,又能简化程序运算强度,提高加工效率。In the NC machining of the gourd,due to the convex and concave change of the outer outline of the gourd,the compound cycle machining instruction of G71 rough lathe has limitations.However,most of the blanks in practical teaching are bar stock,and the use of G73 instruction will lead to too much empty knife walking phenomenon.Based on the contradiction between the two,the application of G71 II cyclic machining instruction rarely mentioned in the textbook to the actual teaching practice can not only solve the problem of convex and concave changes in the machining of the outer contour of parts,but also simplify the operation intensity of the program and improve the machining efficiency.
