ABSTRACT
152Dimensional metrology is one of the cornerstones of mechanical engineering and is key to manufacturing. Dimensions have to be confirmed by measurement, and such measurements allow tolerances and uncertainties to be calculated. Following on from the metrology basics covered in Chapter 2, this chapter will present the multitude of instruments and techniques that are available for dimensional metrology, including the measurement of length, three-dimensional coordinates, and surface form and texture. Single and multi-dimensional measuring instruments will be discussed along with their capabilities and limitations. Reversal methods will also be covered.
