Single Abrasive Finite Element Model of Microgrinding. In the study of microgrinding mechanism, the grinding process of SiC mirror can be simplified to the two-dimensional orthogonal microgrinding finite element analysis model. The hardness and modulus of elasticity of single diamond abrasive are far more than SiC workpiece, even though the ...

The microgrinding force and surface roughness value in-creased with the increase of workpiece feed rate. On the basis of simple single-factor tests, the modified empirical mathe-matical model of the microgrinding surface roughness for Zr-based BMG was established, and the theoretical model of microgrinding force for Zr-based BMGs was verified. The

Microgrinding of LDGC also achieved the best average and maximum roughness values of 0.168 ± 0.013 μm and 3.693 ± 0.467 μm with more than 90% improvement compared with simulated conventional ...

We report a series of microgrinding and polishing experiments on glass–ceramics. Microgrinding includes deterministic microgrinding (two-body abrasion at fixed infeed rate) and loose abrasive ...

The application of silicon carbide (SiC) is often limited due to its low machining efficiency and unpredictability about the results of the grinding process. The aim of this paper is to set up finite element analysis models (FEM) about microgrinding process of SiC, to study the change processes about tangential and normal grinding force which ...
