Active abrasive density increases with an increase in abrasive concentration in the media. Higher the active abrasive density more will be the abrasion and better will be the finishing performance (refer to Fig. 14 (c)) [79, 83]. However, higher abrasive concentration can restrict the flow of media through the workpiece passage [87].

2019-6-19 Design of the abrasive arrangement in the Z direction. In Z direction, the overlap ratio has a great influence on the workpiece surface quality, mainly due to the variation of abrasives number contacting with the workpiece surface during the grinding process. By adjusting the distance of the upper and lower two abrasive layers, the different overlap ratio can be formed, as shown in Fig. 2b.

2020-11-11 Abrasive waterjet machining has been widely used because of flexibility, but the cutting accuracy is difficult to ensure due to the lack of dynamic analysis in the forming process of the kerf. In this paper, a coupled SPH-DEM-FEM method is proposed to predict the cutting qualities of the abrasive water jet machining under different process parameters and reveal the mechanism of the kerf ...

A new abrasive belt has an advantage compared to a grinding wheel due to the grain orientation on a belt. Grinding wheels act harder in grinding than abrasive belts, with a typical hardness of 52 HRC. Abrasive belts are used extensively to grind hardened steels and to grind gray and malleable cast irons and nonferrous alloys.
