Deformation and material removal rate in polishing silicon wafers
Journal of Materials Processing Technology, 2003Abstract The aim of the present work was to explore the deformation mechanism and to estimate the material removal rate (MRR) in polishing silicon wafers. The surface roughness was studied by atomic force microscope and subsurface damage was assessed by means of cross-section transmission electron microscopy.

OPTIMAL MACHINING PROJECT CONTROL WITH MATERIAL REMOVAL RATE
Transactions of the Canadian Society for Mechanical Engineering, 2002A MPC, Machining Project Control, Model to achieve the optimal control of material removal rate (MRR) for a machining project undergoing the considerations of project quantity and production period is established in this study. This paper not only applies material removal rate into the objective function mathematically, but also implements Calculus of

Study on material removal rate of electrolysis and plasma polishing
2012 IEEE International Conference on Information and Automation, 2012Electrolysis and plasma polishing is a new technique that can replace the traditional polishing methods. Analysis on heat transfer process of electrolysis and plasma polishing is performed, from which it is discovered that the workpiece's surface heat flux density has a great effect on the material removal rate.

Modeling of Material Removal Rate in Micro-ECG Process
Journal of Manufacturing Science and Engineering, 2008Microelectrochemical 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 analytical modeling of the material removal phenomenon in micro-ECG process to predict ...

An Intelligent Approach for High Material Removal Rate Machining
2013Machining is one of the most important manufacturing processes. Material removal rate (MRR) is a crucial issue in machining, but it is limited by machining stability lobe which depends on cutting dynamics. This chapter investigates an intelligent approach for increasing MRR.

Pressure and velocity dependence of the material removal rate in the fast polishing process
Applied Optics, 2008Based on the direct contact between the wafer and the pad, the pressure and velocity dependence of the material removal rate (MRR) in the fast polishing process (FPP) is investigated. There are three assumptions of the FPP material removal mechanism: the normal distribution of abrasive size, a periodic roughness of the pad surface, and the plastic ...

Modeling Material Removal Rate of Heavy Belt-Grinding in Manufacturing of U71Mn Material
Key Engineering Materials, 2016The heavy belt-grinding is a new machining method, which combined the characters of heavy-duty grinding and belt-grinding together, with high efficiency and low cost. In the present paper the removal rate model of heavy belt-grinding in manufacturing of U71Mn steel is established. It is assumed that the distribution of the abrasive particles protrusion
