TEMPERATURE COMPENSATION DURING CMM INSPECTION

E. Ratajczyk, M. Dobosz

Abstract

Influence of temperature on CMM inspection results by means of ballplate or hole–plate is presented. Errors of indication of a CMM for length measurement are analyzed. Internal (by machine hardware and software) and external (by additional temperature sensors and software) methods of compensation are compared with measurement without compensation. Implications for industrial practice are formulated.
