Simulation of grinding processes using finite element analysis and geometric simulation of individual grains

Mechanism of the scratching of monocrystalline silicon carbide with a diamond grit at different wear stages

“…After the scratch depth reaches the maximum value, the oscillating force signal appears to decay. The literature 18–21 also describes the phenomenon of the oscillation of the force signal at different degrees in single-diamond-grit scratching. Thus, the first wave of scratching force in Figure 4(a) was used as the force curve of this scratching, as shown in Figure 4(b).…”

New insights into the methods for predicting ground surface roughness in the age of digitalisation

“…They examined the effect of different grinding parameters on the surface topography of the workpiece. Siebrecht et al [21] extended the grinding tool model to predict the surface roughness and the simulated process forces by modelling single diamond grits, which were randomly distributed over the tool and approximated as the intersection of a cube and an octahedron. Chen et al [22] considered random distribution of the grit protrusion heights and the location.…”

Diamond grinding wheels production study with the use of the finite element method

“…The results pertaining to CTE of metallic phase, modulus of elasticity of bond and sintering temperature are consistent with results reported in Refs. [16], [17], [18], [19], [20], [21], [22].…”

“…The actual grinding wheel is replaced by thermal or thermo-mechanical boundary conditions and chip formation is neglected [9]. In the second approach, being a microscopic one, a grain or a group of grains is modeled and their interaction with the workpiece is investigated [15], [16]. These models, usually 3D, use shapes of the grain based on optical observations from actual grinding wheels [17].…”
