Evaluation of a simple inspection tool used for a CMM interim check

Abstract

Coordinate Measuring Machines (CMMs) are widely used in industry as a universal measuring instrument. The validation of reliability of CMM is important for quality assurance. The reverification test or interim check of CMM is, however, not often carried out by general CMM users. The reasons are the cost of the gauges for the test or check and the measuring skills. Therefore a simple inspection tool is expected. In this report, we describe the evaluation results of a simple inspection tool (Renishaw: Machine Checking Gauge) used for a CMM interim check.
