| Outline of Final Research Achievements |
Finishing is a significant processing technology because it achieves good friction/wear character and beautiful appearance. In this study, fundamental investigation on gyro barrel finishing, which is expected to be an excellent finishing process of complicated shape, was conducted. Force acting on workpiece, which affects finishing properties directly, was measured, and its major factor was clarified. Furthermore, it was achieved that its process time decreases to 1/3 by attaching simple device developped by us.
