Abstract
Magnetic field assisted machining uses particle brush formed along a line of magnetic force as a tool. By magnetic force, particle brush gives processing pressure to the surface, and it removes the surface by relative motion between surface and particle brush. And, it has been clarified that electrolyzed reducing water can be used as substitutive cleaning solvent for chemical cleaning solvent. The purpose of this study is to establish precision machining technology which combined the physical removal action by magnetic field assisted machining method with the chemical action by electrolyzed reducing water. In this paper, surface finishing was carried out. Then, effect of grain concentration was examined experimentally. Experimental results are as follows: (1) In initial processing step, removal rate lowers, when grain concentration is low. However, removal rate is improved, after hard layer in the surface was removed, and then, effect of grain concentration on removal rate decreases. (2) Effect of grain concentration on surface roughness of finished surface is small.
