数控铣床编程实例 简单

毛坯为70㎜×70㎜×18㎜板材，六面已粗加工过，要求数控铣出如图2-23所示的槽，工件材料为45钢。

选择机床设备：根据零件图样要求，选用经济型数控铣床即可达到要求。故选用XKN7125型数控立式铣床。

选择刀具：现采用φ10㎜的平底立铣刀，定义为T01，并把该刀具的直径输入刀具参数表中。

确定切削用量：切削用量的具体数值应根据该机床性能、相关的手册并结合实际经验确定，详见加工程序。

确定工件坐标系和对刀点：在XOY平面内确定以工件中心为工件原点，Z方向以工件表面为工件原点，建立工件坐标系，如图2-23所示。 采用手动对刀方法（ *** 作与前面介绍的数控铣床对刀方法相同）把点O作为对刀点。

编写程序：按该机床规定的指令代码和程序段格式，把加工零件的全部工艺过程编写成程序清单。 考虑到加工图示的槽，深为4㎜，每次切深为2㎜，分二次加工完，则为编程方便，同时减少指令条数，可采用子程序。

该工件的加工程序如下（该程序用于XKN7125铣床）：
