加工中心练习题

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.M98P100D1(D=8.2)M98P100D1(D=8.2)M98P100D1(D=8.2)G0Z100.M05G91G28Z0T2M6G90G54G0X0Y0S1000M3G43H2Z100.M98P100D2(D=5.)M98P100D2(D=5.)M98P100D2(D=5.)M98P100D2(D=5.)M98P100D2(D=5.)G0Z100.M05G91G28Z0T3M6G90G54G0X0Y0S1500M03G98G80G80M05G91G28Z0T4M06G90G54G0X0Y0S1500M03G43H4Z08G98G70G80M05G91G28Z0T5M06G90G54G0X0Y0S180M03G43H5Z08G98G40G80M05M09G91G28Z0M30%子程序O100%G41G100G03X-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%O0001G91G28Z0T1M06G90G54G0X0Y0S500M03G43H01Z08G01Z50D01M98P100F80(D01=15)D02M98P100F80(D02=8.2)G0Z50D02M98P200F80(D02=8.2)M05G91G28Z0T2M06G90G54G0X0Y0S500M03G01Z50D03M98P100F120(D03=13.0)D04M98P100F120(D04=5.0)G0Z50D04M98P200F120(D04=5.0)M05M09M30%子程序O100G41G01Y-30.G03X-32.5Y0R30.G40G01Y0M99子程序O200G41GX30.G01X-30.G40M99加工中心标准训练样件三手工编程主程序%O0001G91G28Z0T1M06G90G54G500M03G43H01Z100.G01Z50G01Y80G01Z50D01M98P100F80(D01=8.2)M05G91G28Z0T2M06G90G1000M03G01Z50D02M98P100F120(D02=5.0)G01Z50D03M98P200F50(D03=5.2)G01Z50D02M98P200F120M05M09M30%子程序O100G01GG01G40Y0M99%子程序O200G01GG01G40Y0M99%
