三轴编程代码

① 数控编程P、Q代码什么含义

P：程序开始编号；Q：程序结束编号。

示例：G74R_

G74 X_Z_P_Q_R_F_

P是X方向的移动余量，Q是Z方向的移动余量。

数控编程是数控加工准备阶段的主要内容之一，通常包括分析零件图和确定加工过程 ，计算刀具轨迹以获得刀具位置数据，编写数控加工程序，制作控制介质， 校对程序和第一批试用版。

数控编程有手动编程和自动编程有两种方法。 简而言之，这是从零件图纸到获得CNC加工程序的整个过程。

(1)三轴编程代码扩展阅读：

其他代码的含义：

R：粗车时X轴的回退量，范围为0至99.999（单位：mm / inch，半径值），无符号。

U :X轴精加工余量。

W :Z轴精加工余量（Z轴无余量时可省略）

代码格式：G70 P（ns）Q（nf）；

代码功能：刀具从起点开始沿ns~nf程序段给出的工件精加工轨迹进行加工。

ns：精加工轨道的第一个程序段的段号。

nf：精加工轨道的最后一个程序段的段号。
