我是靠谱客的博主雪白板栗，最近开发中收集的这篇文章主要介绍NETDMIS5.0内孔接近回距离的设置2023，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

在这里插入图片描述

对于偏差较大的工件零件建议增大触测距离和逼近回退近距离，测量空间较小的零件减小逼近回退距离，这需要根据实际情况设置。

探测距离（接近距离）：测头在采点前以探测速度向前移动的距离。

回退速度：机器自动采完点后离开工件时的速度。无自学习指令。

在平时的几何元素测零中，不管是手动测量还是自动测量都需要设定正确的测头参数，防止在测量中发生异常碰撞，关于如何设置正确的探测回退距离，常用的方法有两种:

方法一：在环境设置下——运动控制设置，点击“运动参数”，打开对话框。自动测量修改探测距离，同时会修改回退距离；手动测量修改手动回退距离。

方法二：在自动特征元素测量对话框中，路径参数标签页下勾选“自动回退距离”，软件根据孔的直径和测头参数自动计算回退距离。

探测回退距离的数值设置多少是合适的，测量中不会发生碰撞呢？下面有个公式可以作为参考：

探测回退距离=（孔的直径/槽宽度-测针直径）/2
