Non-contact measurement of grinding pins by means of a 2D laser micrometer

Grinding is one of the most important processes for producing discrete components of advanced materials with high precision. The macroscopic and microscopic analysis of surface topography becomes an essential activity to ensure accurate machining results. Most of the methods used traditionally are carried out off-line so expensive equipment and time consume are required. The present work proposes the use of a 2D laser micrometer to perform on-machine macrogeometric measurement and analysis of grinding pins in order to overcome non-productive time with a fast, precise and reasonably economical inspection equipment, which is easy to integrate in a CNC grinding machine.
