Abstract

In recent years, the CMM (Coordinate Measuring Machine) quickly has been spreading in the manufacturing industry. With this phenomenon, the environmental condition and installation site of CMMs has been changed from the temperature control room to the workshop environment and the production line without air conditioning. However, even in severe environment the demand to high accuracy measurements by CMM has been enhancing still more. Therefore, the methods to evaluate and realize the high accuracy measurements by CMM in workshop environment have been investigated. In this paper, we propose the evaluation and correction method of squareness errors using MCG (Machine Checking Gauge). Additionally the performances of CMM in workshop environment and temperature-controlled room are tested and corrected experimentally. From these results, we confirmed the availability of the proposed methods.
