All you need to know about CMM
CMM i.e. Coordinate Measuring Machine is a device that is used to measure the geometry of the physical objects by using discrete points on the surface with the help of probe. CMM specifies the probe position in terms of its displacement from the reference point in a 3D Cartesian coordinate system. In CMM, probe plays a crucial role as it is the one which sense the discrete points and find the geometric characteristics of the object. There are various types of probe available such as mechanical, optical, laser and white light. The position of the probe can be controlled manually or with the help of computer. Both Manual CMM and automatic CMM are available in market and one can choose as per his requirement. CMM basically allows the movement of the probe in three directions i.e. X, Y and Z which are orthogonal to each other. Each axis on the Cartesian coordinate system has a sensor that monitors the probe’s position on that axis through micrometer precision. When the probe comes...
