Geometry measurement and tool surface evaluation using a focus-variation microscope

Abstract

Possibility of measuring the geometrical features of cutting tools and surface roughness by means of a focus-variation microscope is presented. This technology supports manufacturers in the development of new products and in the quality control of cutting edges and geometry. All measurements, regardless of the application site, are characterized by high resolution, repeatability and traceability. Furthermore, focus-variation microscopy allows measurement of surface irregularities and edge chipping, giving a wide range of possibilities for numerical analysis of edge quality. The technology also provides the stability of measurement results obtained even under production conditions.
