Abstract
Measurements of geometric accuracy in machine tools, especially of errors in moving machine parts against their theoretical axes, are taken by means of displacement pick-ups moving along a reference standard 1,2, such as a cylindrical test specimen. This procedure is impeded by physical form errors in the standards, especially for heavy machines, as well as by adjustment errors in the standards against the machine part to be measured. These disadvantages can be avoided by using a non-material standard like a laser beam with a four quadrant photodiode as sensor and a special analysis of the measurement data.
