概要

The objective of this study is to realize a manipulator of 0.5 mm in outside diameter as a part of 'research and development of micro machine technology.' This manipulator is intended as a part of a working robot to fix or observe the inside wall of a small pipe [1]. One of the important problems of this research is to establish a processing method of a tubular small structure. MIM, metal injection molding, has been adopted to fabricate such a small structure [2], [3]. As a processing method to machine small molds for MIM, finish processing with surface roughness of R_<max> 0.1μm has been under our research applying 'vibrational processing technology,' which was developed on our own [4]. This paper presents the results of 'vibrational processing technology' surface finishing of molds for metal injection.
