doi:10.3901/JME.2017.19.114

Abstract

Abstract: In order to improve the finishing quality and efficiency on titanium taper hole, the ultrasonic vibration is introduced assisting the conventional magnetic abrasive finishing (MAF). The magnetic abrasive particles (MAPs) not only cut the surface but also produced striking effect in finishing process. The cutting edge of MAPs formed multi-directional cutting path under the comprehensive action of magnetic force, vibratory force and centrifugal force. Through contrast experiment with conventional MAF, the material removal, surface roughness and surface morphology are analyzed to verify the efficiency of ultrasonic magnetic abrasive finishing (UMAF). The results show that the finishing efficiency is improved in UMAF; the material removal of taper hole increased to 1.6 times; the average surface roughness from initial Ra1.23 μm decreased to Ra0.25 μm; the decrease rate is 1.3 times compared with conventional MAF process; the bumps, pits and machining textures on the workpiece surface are all removed, the surface quality is significantly elevated and the shape accuracy of workpiece is improved.

Key words: finishing efficiency, magnetic abrasive finishing, surface quality, taper hole, ultrasonic vibration
