By the new figuring method, not only the polishing time decreases but also its efficiency increases by bigger abrasive...

...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...

Lim, Principle Research Fellow This paper presents an analysis of the transient flow, on pump shut-down, in abrasive suspension jet cutting machines as part of an effort to develop a fine-beam cutting system. The analysis was motivated by a need to clearly understand...

...Y. P. Chang; M. Hashimura; D. A. Dornfeld, Fellow ASME, The mechanical material removal (MRR) mechanisms in lapping were investigated, using concepts of two-body vs. three-body abrasion and ductile vs. brittle machining. The statistical nature of the depth of cut in the lapping process...

... that grinding of silicon nitride is accompanied by dulling of the abrasive grains and a significant increase in the grinding forces and power. High wheel speed caused more wheel wear, which was attributed to a longer accumulated sliding length between the abrasive grains and the workpiece. This second paper...
