Abstract
A new evaluation method of geometrical accuracy based on the evaluation of the machined workpiece has been developed. The strategy of our evaluation utilizes coordinates measuring machine (CMM) as a master gauge because of its accuracy so that machine operator devote himself to machining and estimator of accuracy dedicate in measurement. In our study, the non rotational machining is applied to realize the proposed evaluation. Machining error except the geometric accuracy of a machining centre is neglected by setting the cutting condition not to affect the desired machined workpiece previously. The measured results are enough accurate compared with those by the square master gauge calibrated previously. In this report, the machining setup and the evaluated results are shown with the experimental procedure.
