加工中心标准训练样件一注：铣削外轮廓时，最佳走刀轨迹，先将刀具移出工件，远离毛坯（具体的坐标点要综合考虑毛坯的尺寸、刀具半径补偿值，及坐标点是否容易计算（如比工件大10，20，30mm然后走10，20，30mm的圆弧切入），另外就是尽量不要让刀具的底刃切削否则刀具会颤动），然后快速接近工件（G00 Z 5.），再G01 Z-7.F50（向下进给时一定要慢），然后带刀补走到圆弧切入的起始点，圆弧切入，走轨迹，圆弧切出，抬刀取消刀补移动到起始点。切削内孔时，1）可以软件编程，螺旋线下刀，铣刀可以是立铣刀，刀心没有横刃； 2）先在要铣削的部位打个孔，然后让铣刀从孔处进刀； 3）采用带有横刃的螺纹槽铣刀，下刀时进给速度一定要慢。手工编程主程序%o1G91G28Z0.T1M6G90G54G0X0Y0S500M3G43H1Z100.X-65.Y0Z5.0G01Z-8.F50M98P100D1(D=8.2)G01Z-16.F50M98P100D1(D=8.2)G01Z-24.F50M98P100D1(D=8.2)G0Z100.M05G91G28Z0T2M6G90G54G0X0Y0S1000M3G43H2Z100.X-65.Y0Z5.0G01Z-5.F50M98P100D2(D=5.)G01Z-10.F50M98P100D2(D=5.)G01Z-15.F50M98P100D2(D=5.)G01Z-20.F50M98P100D2(D=5.)G01Z-24.F50M98P100D2(D=5.)G0Z100.M05G91G28Z0T3M6G90G54G0X0Y0S1500M03G43H3Z100.0G98G81R5.0Z-5.0F80G80M05G91G28Z0T4M06G90G54G0X0Y0S1500M03G43H4Z100.0M08G98G83R5.0Z-42.0Q2.0F70G80M05G91G28Z0T5M06G90G54G0X0Y0S180M03G43H5Z100.0M08G98G81R5.0Z-45.0F40G80M05M09G91G28Z0M30%子程序O100%G41G01X-65.Y-30.0F100G03X-35.Y0R30.G01Y32.G02X-32.Y35.R3.G01X32.G02X35.Y32.R3.G01Y-32.G02X32.Y-35.R3.G01X-32.G02X-35.Y-32.R3.G01Y0G03X-65.0Y30.R30.G40G01Y0M99%加工中心标准训练样件二手工编程主程序%O0001G91G28Z0T1M06G90G54G0X0Y0S500M03G43H01Z100.0M08X-65.Y0Z5.0G01Z-12.8F50D01M98P100F80(D01=15)D02M98P100F80(D02=8.2)G0Z-7.8F50D02M98P200F80(D02=8.2)G0Z100.0M05G91G28Z0T2M06G90G54G0X0Y0S500M03G43H02Z100.0X-65.0Y0Z5.0G01Z-13.0F50D03M98P100F120(D03=13.0)D04M98P100F120(D04=5.0)G0Z-8.0F50D04M98P200F120(D04=5.0)G0Z100.0M05M09M30%子程序O100G41G01Y-30.G03X-32.5Y0R30.G02X0Y32.5R32.5X32.50Y0R32.5X0Y-32.5R32.5X-32.5Y0R32.5G03X-62.5Y30.0R30.0G40G01Y0M99子程序O200G41G01X-30.Y25.0X30.G02X30.Y-25.R32.5G01X-30.X-62.5Y0G40M99加工中心标准训练样件三手工编程主程序%O0001G91G28Z0T1M06G90G54G0X28.0Y35.0S500M03G43H01Z100.Z5.0G01Z-12.0F50G01Y24.0F80X35.0Y-24.0X28.0Y-40.0X-28.0Y-24.0X-35.0Y24.0X-28.0Y40.0X28.0G0Z20.0X51.0Y0Z5.0G01Z-3.8F50D01M98P100F80(D01=8.2)G0Z100.0M05G91G28Z0T2M06G90G54X51.0Y0S1000M03G43H02Z100.0Z5.0G01Z-4.0F50D02M98P100F120(D02=5.0)G01Z-11.8F50D03M98P200F50(D03=5.2)G01Z-12.0F50D02M98P200F120G0Z100.0M05M09M30%子程序O100G01G41Y30.0G03X21.0Y0R30.0G02I-21.0J0G03X51.0Y-30.0R30.0G01G40Y0M99%子程序O200G01G41Y30.0G03X21.0Y0R30.0G02X14.0Y-15.6525R21.0G03X12.0Y-20.1246R6.0G01Y-24.0G02X6.0Y-30.0R6.0G01X-6.0G02X-12.0Y-24.0R6.0G01Y-20.1246G03X-14.0Y-15.6525R6.0G02Y15.6525R21.0G03X-12.0Y20.1246R6.0G01Y24.0
