Outline of Final Research Achievements

The purpose of this research is to clarify the cause of the occurrence of the periodic and local pattern which occurs when complicated shape parts are finished with 5 axis machining center. In particular, what kind of error will appear with regard to the cause of appearance of such a pattern thought that plural errors appear as integrated can be clarified by simulation and experiment. Based on the results, we develop a technology to identify the cause of error inherent in 5 axis machine such as geometric error, mechanism error, servo system error, and diagnose cause of pattern appearing on complicated shape processed surface.
