Description

Technical Field

[0001] The utility model relates to the technical field of coordinate measuring machines, in particular to a bridge type coordinate measuring machine. Background Art

[0002] The coordinate measuring machine (CMM) is the most representative coordinate measuring instrument. In a coordinate measuring machine, a mechanical coordinate system is established with the platform of the measuring instrument as the reference plane, the coordinate values ​​of the measured points on the surface of the workpiece are collected, and projected into the spatial coordinate system to build a spatial model of the workpiece. In coordinate measurement technology, we first need to establish an actual visible coordinate system through mechanical methods, and then correspond the measuring points one by one using coordinate representation methods, and then use spatial geometric relationships to obtain the required measurement values. For example, in a coordinate measuring machine, we establish a mechanical coordinate system with the platform of the measuring instrument as the reference plane, collect the coordinate values ​​of the measured points on the surface of the workpiece, and project them into the spatial coordinate system to build a spatial model of the workpiece. With the spatial model of the workpiece, the coordinate measuring machine can calculate the required geometric parameters.
