Abstract This investigation reveals the paradigm of EDM in this experiment to expel the metal from Al7075 with a performed Copper electrode. Aluminium7075 has the most elevated quality, higher firmness, and diminished thickness. Aluminium7075 is utilized prevalently in exceedingly focused on applications, for example, brackets, milk churns, mineral ...

Precision Measurements Of Material-Removal Rates In Superpolishing Sapphire
SPIE Proceedings, 1989As we demonstrate, sapphire can be polished by means of colloidal SiO2 (7 nmφ) in water by direct contact to a tin lap to a residual roughness better than 0.3 nm Rz measured with a Talystep profilometer. We use the superpolishing mechanism itself for producing microscopically smooth grooves which can serve for a precision measurement of the very small ...

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.

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.

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.

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 ...

Modelling the effect of tool material on material removal rate in electric discharge machining
Materials Research Proceedings, 2023Abstract. 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 ...
