数控铣床加工零件凸台的外轮廓,刀具补偿的应用

采用刀具半径左补偿,数控程序如下;

N0010 G54S1500 M03/设工件零点于O点,主轴正转1500r/min

N0020 G90G00Z50./抬刀至安全高度

N0030 X0Y0../刀具快进至(0,0,50)

N0040 Z2./刀具快进至(0,0,2)

N0050 G01Z-3.F50./刀具以切削进给到深度-3mm处

N0060 G41X20.Y14.F150./建立刀具半径左补偿O—A

N0070 Y62./直线插补A—B

N0080 G02X44.Y86.I24.JO/圆弧插补B—C

N0090 G01X96./直线插补C——D

N0100 G03X120.Y62.I24.J0/圆弧插补D—E

N0110 G01Y40./直线插补E—F

N0120 X100.Y14./直线插补F—G

N0130 X20./直线插补G一A

N0140 G40XOY0/取消刀具半径补偿A一O

N0150 G00Z100./Z向快速退刀

N0160 M02/程序结束
