| Outline of Final Research Achievements |
The research project performed generalization of the form shaping function regarding non-orthogonal type 5-axis machining centers that allow slanted axes. Furthermore, an analysis method to represent the machinable area using the generalized form shaping function was developed. As the results, we achieved to derive the generalized form shaping function, and conditions that can determine arbitrary positions and postures of a tool according to formed angles in each axis. Also, we achieved to represent “machining area” analytically, which is one of important criteria regarding development of new five-axis machine tools. From the above outcomes, it can be expected that the leading method of five-axis machine tools with maximized machining area will be available.

複雑な軸構成を持った工作機械の開発は組立精度や加工精度の観点から現実的でなかったが，今後全く新しい軸構成を持った工作機械を開発する上で，本研究成果はその先駆的な役割を果たしている．例えば，傾斜回転軸を有する5軸工作機械を新たに開発する場合，加工スペースを最大化する機械構造や，特異点を回避しやすい機械構造など，工作機械に求められる種々の特性に対して最適化された機械構造の創発に繋がることが期待できる．
