The results of grinding are highly dependent on conditions of workpiece removal process. The material is removed by an unspecified number of abrasive grains of irregular shape and random distribution on the grinding wheel active surface. The interaction between the abrasive grain and the workpiece can be divided into three stages: (i) rubbing, (ii) ploughing and (iii) chip formation ...
Fig. 2 illustrates the surface grinding process. Grinding wheels are resin-bond diamond cup wheels. The workpiece (wafer) is held by the porous ceramic chuck using vacuum. The axis of rotation for the grinding wheel is offset a distance of the wheel radius relative to the axis of rotation for the wafer. During grinding, the grinding wheel and ...

In hard gear process dynamic, hobbed and/or shaped, or warm forged/rolled gears after heat treatment undergo final finishing operation, such as hard finishing, honing, or grinding. Overall economy becomes the deciding factor for selection of the process dynamic.
Automatic grinding of toroidal mirrors was tried [3]. The principle of the method is to shape a toroid-shaped (barrel-shaped) grinding wheel and control the relative position of the workpiece and the grinding wheel in the grinding process. Two kinds of grinding operations are possible.

Research in the field of machining in testing the level of roughness needs to be done to get good results in the machining process. The purpose of this study was to determine the effect of variations in feeding on the surface grinding process on the surface roughness and hardness of S45C carbon steel that has gone through processes including induction, quenching and tempering and to …
Proses penggilingan merupakan pra-proses dalam pengolahan agar didapatkan bahan yang siap untuk diolah. Penggilingan memiliki tujuan yang sangat penting, hal ini dilakukan untuk mengurangi ukuran partikel suatu bahan. Penggilingan dikatakan optimal jika mampu menggiling bahan dengan konsumsi energi yang rendah. Penggilingan tongkol juga
The thinning process was divided into six procedures, covering the rough grinding (ⅰ and ii), fine grinding (iii, iv, and v), and stress-relief processes (vi) of wafers. Procedure ⅰ was the rough grinding with the SD800 at 0.2 MPa, which was intended to achieve a fast and efficient material removal.

A large number of studies have shown that the height of a residual material is the key factor affecting the surface quality of ultra-precision grinding. However, the grinding process contains several random factors, such as the randomness of grinding particle size and the random distribution of grinding particles, which cause the complexity of the material removal process. In this study ...
