Coordinate Measuring Machine

A Coordinate Measuring Machine is a device for measuring physical geometrical of characteristic of an object. This Machine may be manually controlled by an operator or it may be computer controlled Measurement are defined by a probe attached to third moving axis of this machine. This probe touch the part of interest and allows collecting discrete points on the object surface's. The typical CMM is composed on three axes X,Y, and Z. These axes is orthogonal to each other in typical three dimensional coordinate system. Each Axis has a very accurate scale system that indicates the Location of that Axis. All three Axes are digital Display readout. The Probe is used to touch different spot of the part being measured. The Machine then uses the X,Y,Z coordinates of each these points to determine size and position. The next generation of scanning, known as laser scanning. This Method use laser beams that are projected against the surface of the part. Many thousand of points can be taken and used to not only to check the size and position, but also to create a 3D image of the part as well. This point cloud of Data can then be transffered to CAD Software to create a working 3D Model of the part.
