...Chunhui Chung; Chad S. Korach; Imin Kao In this paper, the lapping process of wafer surfaces is studied with experiments and contact modeling of surface roughness. In order to improve the performance of the lapping processes, effects of mixed abrasive grits in the slurry of the free abrasive...

...JiAn Duan; DeFu Liu The purpose of this paper is to reveal material removal mechanisms of optical fiber end-surface in lapping processes. The lapping process experiments are conducted using fixed diamond abrasive lapping films with various particle sizes of 6 μ m , 3 μ m , 1 μ m , and 0.5 μ m...

... of the grooves generated on the work-material and the shape of the groove sides. Surface texture consists of two components: deterministic, resulting from the nominal wheel active surface, and random, resulting from the random shape and arrangement of abrasive grains. The limited contribution of the random...

...Kamal K. Kar; N. L. Ravikumar; Piyushkumar B. Tailor; J. Ramkumar; D. Sathiyamoorthy The abrasive flow machining (AFM) is used to deburr, radius, polish and remove recast layer of components in a wide range of applications. Material is removed from the workpiece by a flowing semisolid mass across...

...Hitomi Yamaguchi; Kotaro Hanada Magnetic abrasive used for the internal finishing of capillary tubes, which prevents accumulation of contamination and erratic flow of the conveyed fluid, is a composite particle, consisting of iron and Al 2 O 3 abrasive grains. The irregularity of the magnetic...

...Kishore S. Gaikwad; Suhas S. Joshi Microelectrochemical grinding (micro-ECG) is a variant of electrochemical grinding (ECG) process, in which material is removed by a combination of electrolytic dissolution and abrasive action that take place in a small interelectrode gap. This paper discusses...

...Masahiro Mizuno; Toshirou Iyama; Bi Zhang This study simulates the sawing process with an abrasive circular saw blade and analyzes the generation of cutoff surfaces in the sawing process with the consideration of the blade deflection caused by the asymmetric wear of the blade outer edge...

...M. Barletta; D. Ceccarelli; S. Guarino; V. Tagliaferri The relatively new technique of fluidized bed assisted abrasive jet machining (FB-AJM) is applied to finishing the inner surfaces of tubular Inconel 718 components. The effects of abrasive size, jet pressure, and machining cycle were evaluated...

...Hitomi Yamaguchi; Takeo Shinmura; Ryota Ikeda This paper studies the internal finishing of capillary tubes using a magnetic abrasive finishing process. Such tubes are used with nanoscale technologies and meet the demands of the present age in medical and chemical equipment. The finishing...

... range of conditions on hardened bearing steel with wheels containing different abrasive grain sizes. The radial wheel wear was characterized in each case by an initial transient at a progressively decreasing rate to a steady-state wear regime at a nearly constant rate until the end of the wheel life...

...Wook-Bae Kim; Seung-Hwan Lee; Byung-Kwon Min A surface-finishing method for three-dimensional microchannel structures is proposed. The method utilizes magnetorheological fluid mixed with abrasives as a polishing tool. The influences of the process parameters on the material removal were...

... that, for an isolated shallow scratch, the material is mainly plowed sideway along the track of the abrasive particle with no net material removal. However, it is observed that material is detached close to the intersection zone of two scratches. Motivated by this observation, it is speculated that the deformation...
