Abstract
Test methods for simultaneous three-axis control movements with two linear axes and a rotary axis will be specified as an ISO standard for checking the accuracy of five-axis machining centers. Two kinds of measuring instruments are proposed for the measurement. One is a ball-bar measuring system with a single sensitive direction and the other is an instrument having three sensors, which is called as "R-test measuring system." In this paper, we confirmed the compatibility between the two measuring systems through experimental works on several five-axis machining centers.
