In-process out-of-roundness measurement probe for turned workpieces

Abstract A new in-process and non-contact probe is proposed to measure the diameter and the roundness of turned workpieces. The initial probe discussed in previous publications exhibited diameter measurements with good accuracy (uncertainty 5 μm over 100 mm). This paper discusses the implementation of roundness measurement into the initial probe and its performance. The principle of the roundness measurement is based on the relationship between the displacement and the light intensity. The probe delivers a maximum error of 0.5 μm with an uncertainty of 1 μm for roundness measurement over a range of 100 mm diameter.
