Software development to analyze the machining test for the identification of rotary axis error motions on five-axis machine tools   Soichi Ibaraki, Shota Tsujimoto, Yu Nagai, Yasutaka Sasaki, Shigeki Morimoto, Yosuke Miyazaki       Abstract   We proposed a machining test for five-axis machine tools. This paper presents a software to help performing this machining test, and then to analyze the test result. By measuring geometric errors of the finished test piece, error motions of rotary axes, as well as geometric errors of rotary axis average lines, can be numerically identified based on the machine's kinematic model. An experimental application example to a large-size five-axis machine with two rotary axes in the spindle side is presented.   Key words: five-axis machine tool, machining test, geometric errors, error calibration         >> Back to Home
