5軸制御マシニングセンターの運動精度の向上に向けた新たなキャリブレーション手法の開発に取り組んだ.また、直進および旋回軸の各種の運動誤差要因を診断する手法を構築した.さらにサーボ系の位置フィードバックで,サーボ系に起因する運動誤差の診断法も提案した.旋回軸にDDモータ方式を採用することで機械全体のサーボ特性を大きく改善できることも解明した.最後に,複雑形状の実加工により開発機で高い加工精度を確認することができた. / A new calibration method to improve the motion accuracy of a 5-axis control machining center has been developed. A method to diagnose various causes of motion errors on linear and rotary axes has been also established. Furthermore, a diagnosis method of motion errors caused by servo motors using the position feedback function is suggested in this paper. This study also figured out employing the direct drive motor for the rotary axes improved the characteristics of all the servo motors on the machine. Finally, the development test machine proved its high machining accuracy through actual machining of a complex-shaped workpiece. / 博士(工学) / Doctor of Philosophy in Engineering / 同志社大学 / Doshisha University
