Chapter 2

Testing of Geometrical Accuracy Parameters of Machines

The geometric accuracy parameters of machines and instruments are discussed in this chapter, and various parameters, such as straightness, perpendicularity, flatness, pitch, yaw, roll, and so on, are introduced. The 21 detailed geometric errors of three coordinate machines together with some supplementary parameters are covered in detail. The principal processes of measurement of these parameters are explained and arrangements for their control are discussed.

Machine accuracy testing methods common for many computer numerically controlled (CNC) machines, coordinate measuring machines (CMMs), and measuring instruments are covered. CMM tests, as specified in ISO standards, include ...
