The quality of indexable inserts is highly dependent on their geometry and surface properties. Durability, feed rates and overall machining properties are influenced by the cutting geometry such as cutting angle and radius. Traditionally, quality assurance methods for geometry accuracy have been restricted to tactile methods. However, tactile measurement devices do not allow the measurement of specific radii or angles due to the mechanical contact of the stylus to the surface. The optical 3D measurement device InfiniteFocus removes inaccuracies caused by tactile inspection methods. It provides highly accurate measurement of angle and profile plus the additional functionality of roughness, waviness. Also, the analysis of faults such as pits, scratches and contamination is possible. Due to the optical inspection quality, output and tool durability become approved.
