The optical setup for the X-axis calibration is shown in fig below. In this fig the laser head is mounted on the tripod stand and its height is adjusted corresponding to the working table of CMM. The interferometer contains a polarized beam splitter which reflects F1 component of the laser beam. Now, let the F2

The various types of CMM Co-ordinate measuring machine are, Cantilever type. Bridge type. Horizontal boring type. Vertical boring type. Cantilever type It is easy to load and unload, but it is most sensitive to mechanical error because of sag or deflection in y axis beam. Bridge type It is difficult to load but less sensitive

Construction of CMM: The co-ordinate measuring machines has movements in X-Y-Z which can be easily controlled and measured. Each slide in three in three directions has transducer which gives digital display and senses +ve/-ve direction. The measuring head has a probe tip, which can be different kinds like taper tip, ball tip etc. Length bar
