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
  01:
  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。   02:
  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。   03:
  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   336:
  0.3   精车外圆   T2   外圆精车刀   475:
  0.08   切退刀槽   T3   切槽刀   336:
  0.05   车螺纹、凹弧   T4   螺纹刀   170:
  1.5   切断   T3   切槽刀   336:
  0.05   04:
  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;   X19.8   X27.8Z-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;   G00X30.0Z5.0   G92X28.4Z-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   参考程序   01:
