Pressure and velocity dependence of the material removal rate in the fast polishing process

Applied Optics, 2008
Based 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 ...

An Intelligent Approach for High Material Removal Rate Machining

2013
Machining 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.

Modelling the effect of tool material on material removal rate in electric discharge machining

Materials Research Proceedings, 2023
Abstract. Present study aims at modelling the impact of tool materials such as copper, tungsten carbide and brass tool on the electric discharge machining of AISI 202 stainless steel. It is well known that the electrical conductivity of tool material has an influence on the current density passed through interelectrode gap and hence sparking process ...

Material removal mechanism and material removal rate model of polishing process for quartz glass using soft particle

SPIE Proceedings, 2015
Fiber arrays are used to connect arrayed waveguide chips. The end-faces of fiber array components are multi-materials non-uniform surfaces. Their low polishing quality has become a bottleneck that restricts coupling performance of integrated photo-electronic devices.
