Measurements performed with respect to imperfect references, characterizing most inprocess measurement situations, must be corrected to account for the error caused by this fault. A theoretical model expressing the influence of axis error motions on the measurement error is formulated for an arbitrary measuring task, and also for typical cylindricity and roundness measuring configurations. To be able to correct for axis error motions a laser-based sensor system for the measurement of rigid body motions of an axis of rotation is proposed. A detailed theoretical analysis of the sensor is performed including the influence of manufacturing errors, component tolerances and sensitivities. Based on this general purpose device specific inprocess sensors are discussed for roundness and cylindricity measurements.
