数控车简单零件综合编程实例
很多人不了解数控车简单零件综合编程，下面就给大家看一下数控车简单零件综合编程实例。
操作方法
确定加工路线：按先主后次，先粗后精的加工原则确定加工路线，采用固定循环指令对外轮廓进行粗加工，再精加工，然后车退刀槽，再加工螺纹，最后切断。装夹方法和对刀点的选择：采用三爪自定心卡盘自定心夹紧，对刀点选在工件的右端面与回转轴线的交点。
刀具的选择：根据加工要求，选用四把刀，1号为粗加工外圆车刀，2号为精加工外圆车刀，3号为切槽刀，4号为车螺纹刀。采用试切法对刀，对刀的同时把端面加工出来。
各工序的切削参数：加工工序刀具号刀具类型主轴转速S( )进给速度F( )粗车外圆T1外圆车刀3360.3精车外圆T2外圆精车刀4750.08切退刀槽T3切槽刀3360.05车螺纹、凹弧T4螺纹刀1701.5切断T3切槽刀3360.05
程序编制，确定工件右端面与轴心线的交点O为编程原点，零件的加工程序如下：程序说明O0004;N1;工序(一)外形轮廓粗加工G40G97G99T0101;M43;M03;G00X40.0Z1.0;G71U1.5R0.5;G71P10Q11U0.5W0.1F0.15;N10G00G42X0;G01Z0;X19.8X27.8Z-20.0;X28.0;Z-45.0;X36.0Z-50.0;Z-59.0;N11G01G40X40.0;G00X100.0Z100.0;N2;工序(二)外形轮廓精加工T0202;M44;G00X40.0Z1.0;G70P10Q11F0.08;G00X100.0Z100.0;N3;工序(三)切槽加工T0303;M43;G00X30.0Z-24.0;G01X24.0F0.05;G01X30.0F0.2;G00X100.0Z100.0;N4;工序(四)锥螺纹与凹圆弧加工T0404;M41;G00X30.0Z5.0G92X28.4Z-22.0R-5.4F1.5;X27.8;X27.4;X27.2;X27.0;X26.9;X26.85;X26.85;G00X32.0;Z-27.0;M44;M98P041234;调用O1234子程序4次加工凹圆弧面G00X100.0Z100.0;N5;工序(五)工件切断T0303;M43;G00X40.0Z-59.0;G75R0.5;G75X0P2000F0.05;G00X100.0Z100.0;M05;M30;程序结束O1234;子程序G01U-1.0F0.1;刀具每次径向进刀1mm加工凹圆弧面G02U0W-18.0R20.0;G01U3.0F0.5;W18.0;U-3.0;M99;子程序调用结束
