Abstract
Recently, a new method of quickly evaluating the machining accuracy of 5-axis machining centers has been proposed, and named this method ‘groove-matrix machining’. This method requires machining each sets of grooves arrayed in a matrix on a test piece mounted on a tilting rotary table, with its tilt or rotation angle changed. Under these conditions, machining accuracy can be evaluated from the test results. In our previous paper, however, the capability of estimating geometric errors inherent to 5-axis machines was not discussed when using groove-matrix machining. This paper proposes the use of ‘groove-matrix machining’ as a method to estimate the geometric errors from the machined workpiece, and confirms its effectiveness.
