用35度刀尖角的外圆刀加工。
第一步：选择刀具。用35度刀尖角的外圆刀加工。
第二步：编程。假设数控系统为FANUC系统，材料直径为Φ28，用G73编程，数控程序如下：M03 S2000 T0101G0 X30.0 Z1.0G73 U13.0 W0 R10G73 P10 Q20 U0.5 W0 F0.2 S1500N10 G0 X2.0G1 Z0 F0.1G3 X4.0 Z-1.0 R1.0G1 Z-3.2G2 X8.0 Z-5.0 R2.23G3 X13.43 Z-19.57 R8.28G2 X14.0 Z-26.34 R4.79G3 X15.87 Z45.47 R11.0G2 X14.0 Z-47.17 R2.0Z-55.0N20 X28.0G70 P10 Q20G0 X100.0 Z100.0M30切断及平端面程序略
