In this work a prototype of a flexible electro-optical measuring machine suitable for dimensional quality control of inner and outer diameters of mechanical workpieces, is presented. Two measuring probes are displaced by means of motorized slides over a range of ± 100 mm enabling the measurement of diameters from 0 up to 200 mm. The position of the probes is gauged by a double interferometer designed for the application. The characterization of the prototype has shown that repeatability and accuracy are better than ± 0.16 μm.

Abstract
In this work a prototype of a flexible electro-optical measuring machine suitable for dimensional quality control of inner and outer diameters of mechanical workpieces, is presented. Two measuring probes are displaced by means of motorized slides over a range of ± 100 mm enabling the measurement of diameters from 0 up to 200 mm. The position of the probes is gauged by a double interferometer designed for the application. The characterization of the prototype has shown that repeatability and accuracy are better than ± 0.16 μm.File in questo prodotto:
