我是靠谱客的博主美满滑板，最近开发中收集的这篇文章主要介绍NETDMIS5.0RPS找正——6点迭代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

主要应用于工件坐标系原点不在工件本身、或无法找到相应的基准元素（如面、孔、
线等）来确定轴向或原点，多为曲面薄壁、钣金类零件（汽车、飞机的配件，这类零件的坐标系多在车身或机身上）。

找正原理：用点性元素(如:点、圆、椭圆、球、方槽、圆槽）进行找正。

1.第一组特征将拟合平面特征，必须使用矢量相近的至少三个特征建立当前工作平面法线轴的方向，空间旋转确定第一轴和坐标原点。

2.第二组特征将拟合直线特征，必须使用至少两个特征从而将工作平面的定义轴旋转到特征点上，平面旋转确定第二轴，确定第三轴的坐标原点。

3.最后一组特征用于确定第二轴的坐标原点。

4.尽可能的保证这三组特征之间有近似垂直关系。

例如以 6 个点进行找正（一个测针角度进行测量）

导入模型，设置安全平面。
在【环境设置】 →【安全平面设置】中设置安全平面

2.使用自动测量点或自由曲线中的矢量点功能，生成程序并手动测量目标元素六个点。

3.打开 RPS 找正界面，用鼠标左键拖拽元素分别到三个列表中或用鼠标在要添加列中点击，用鼠标中键添加元素到相应列即可。

在轴向中会自动选择轴方向及坐标原点，也可以手动改变。注意：这里都是确定坐标系
原点的方向。

根据需要设置合适的公差、点目标半径后，点击【找正】查看偏差值。如果误差较大在运行程序重复测量时可能发生碰撞，请检查参数是否设置正确或因手动测量位置差太多可重新测量元素。

5.5.点击【确定】生成程序如下图所示。此时当前坐标系为第一次找正后的坐标系。 RPS 生成的程序有四个节点，坐标系 1_RPS 节点是将建好的坐标系保存，从开始运行程序时回调坐标系， LOOP 节点是 RPS 循环测量的跳转标签，会自动添加到手动测量的第一个元素的前面。如果定义安全平面指令在第一个元素指令前， LOOP 节点会自动添加到定义安全平面的前面。如下图所示：
