数控铣床圆编程时I J表示起点坐标与圆心坐标的差值,其中I是相对X轴而言,J是相对Y轴而言。
I J的正负取值可以用起点坐标减去圆心坐标,若相减差值为正,即值为正,差值为负,则值为负。例如:圆心坐标为(30,10),起点坐标为(30,0),那么I等于0,J等于-10.
圆编程举例:
编程加工一个直径为50的圆,该圆圆心坐标为(10,-10)。
程序如下:G03 (G02) I10 J-10 R50
其中,G03为逆时针方向圆弧切削,G02为顺时针方向圆弧切削,在多数情况下均将GO3逆时针圆弧切削视为顺铣切削。

数控铣床加工特点:
加工精度高,产品质量稳定;
劳动生产效率高;
加工零件的适应性强,灵活性好;
减轻工人劳动强度;
生产管理水平提高。
一般来说,数控铣床适用于加工数量较少、加工方法复杂程度高、产品品种变换频繁的零件。
