Measurement and Monitoring

This book presents the main methods and techniques for measuring

and monitoring the accuracy of geometrical parameters of precision

Computer Numerically Controlled (CNC) and automated machines,

including modern coordinate measuring machines (CMMs). Highlights

include:

¿ Standard methods and means of testing, together with methods

newly developed and tested by the authors;

¿ Various parameters, such as straightness, perpendicularity, flatness,

pitch, yaw, and roll, as well as the principal processes for measurement

of these parameters;

¿ Lists and tables of geometrical accuracy parameters, together with

diagrams of arrangements for their control and evaluation of measurement

results;

¿ Special methods and some original new devices for measurement

and monitoring, information measuring systems (consisting of laser

interferometers, photoelectric raster encoders or scales, etc.), and

methods for the measurement and testing of circular scales, length

scales, and encoders;

¿ Methods for measuring small lengths, gaps, and distances between

two surfaces;

¿ Examples showing the suitability of mechatronic methods for high

accuracy correction of machines; and

¿ Particular attention is given to the analysis of ISO written standards

of accuracy control, terms and definitions, and methods for evaluation

of the measurement results during performance verification.
