数控编程课的主要目标是使学生掌握数控机床程序编制设计方法步骤,能够根据零件图制定合理的数控加工工艺路线,选取合理的切削用量进行数控机床的操作。笔者在数控编程教学中尝试搞好“三个一”,达到了较好的教学效果。 The main goal of CNC programming class is to enable students to master CNC machine tool program design method steps, according to the parts map to develop a reasonable CNC machining process line, select a reasonable amount of cutting CNC machine tools. The author attempts to improve “three one” in the teaching of numerical control programming to achieve a better teaching effect.
