G00—快速定位
格式:G00 X(U)__Z(W)__
说明:(1)该指令使刀具按照点位控制方式快速移动到指定位置。移动过程中不得对工件
进行加工。
(2)所有编程轴同时以参数所定义的速度移动,当某轴走完编程值便停止,而其他
轴继续运动,
(3)不运动的坐标无须编程。
(4)G00可以写成G0
例:G00 X75 Z200
G0 U-25 W-100
先是X和Z同时走25快速到A点,接着Z向再走75快速到B点。
G01—直线插补
格式:G01 X(U)__Z(W)__F__(mm/min)
说明:(1)该指令使刀具按照直线插补方式移动到指定位置。移动速度是由F指令
进给速度。所有的坐标都可以联动运行。
(2)G01也可以写成G1
例:G01 X40 Z20 F150
两轴联动从A点到B点
G02—逆圆插补
格式1:G02 X(u)____Z(w)____I____K____F_____
说明:(1)X、Z在G90时,圆弧终点坐标是相对编程零点的绝对坐标值。在G91时,
圆弧终点是相对圆弧起点的增量值。无论G90,G91时,I和K均是圆弧终点的坐标值。
I是X方向值、K是Z方向值。圆心坐标在圆弧插补时不得省略,除非用其他格式编程。
(2)G02指令编程时,可以直接编过象限圆,整圆等。
注:过象限时,会自动进行间隙补偿,如果参数区末输入间隙补偿与机床实际反向间隙
悬殊,都会在工件上产生明显的切痕。
(3)G02也可以写成G2。
例:G02 X60 Z50 I40 K0 F120

我们是802d车床,一般只用m3458---40~48--30-00-9。就这些,起它的全用模块就行了。
