2.2. Vibration Modeling of the Flat Surface Grinding Process. A free-body diagram of the flat surface grinding process with forces acting on the grinding wheel and the workpiece is indicated in Figure 2.There is a normal grinding force (), which acts due to the chip formation, and a normal grinding force (), which acts due to the friction between the wheel and the workpiece in the .
Application results of grinding experiments show that very high workpiece quality can be reached, e.g. a roughness Ra of 5 nm with glass workpieces. Truing and recoating techniques are discussed for reuse of worn CVD diamond grinding wheels. Micro grinding tools (abrasive pencils, burrs) can be manufactured with the same coating technology.
Feb 01, 2020· The increasing demand for micro components and features in ceramic materials has led to the development of bonded micro abrasive processes such as micro grinding with micro pencil grinding tools (MPGTs) or thin dicing blades [1,2].Compared to other tool based micro machining processes, micro grinding has several advantages when machining hard and brittle materials [3,4].

Contact stiffness is an important parameter for describing the contact behavior of rough surfaces. In this study, to more accurately describe the contact stiffness between grinding surfaces of steel materials, a novel microcontact stiffness model is proposed. In this model, the novel cosine curve-shaped asperity and the conventional Gauss distribution are used to develop a simulated rough surface.
