Future Trends in Machine Monitoring and Performance Verification of Coordinate Measuring Machines

Measurements of geometrical parameters of parts are normally performed on very expensive 3D measuring equipment, known as coordinate measuring machines (CMMs). Coordinate measuring machines have a high precision mechanical base equipped with very high precision slideways (often made of granite parts) of the highest accuracy requirements for straightness, perpendicularity, flatness, and so on. Quite expensive linear displacement transducers or rotary encoders are mounted into every axis of measurement. CMMs are an example of highly complex, precise and highly expensive equipment. Nevertheless, the very fast development of optical, radio, ...
