Grinding is a complex material removal process with a large number of parameters influencing each other. In the process, the grinding wheel surface contacts the workpiece at high speed and under high pressure. The complexity of the process lies in the multiple microscopic interaction modes in the wheel-workpiece contact zone, including cutting, plowing, sliding, chip/workpiece friction, chip
2010-5-17 The methodology enables the description of the â€˜inside storyâ€™ in grinding processes from a microscopic point of view, which also helps explain and predict the time dependent behavior in grinding. Furthermore, the process model can be used for grinding force (or power) estimation for multiple-stage grinding cycles which includes
2021-5-1 The aim of the work was to create a stable FEM model of the wet semi-autogenous grinding process and to quantify the efﬁciency of processing copper–nickel ores under given conditions. The SAG 34 17 model was created by the discrete element method and computational ﬂuid dynamics in Rocky DEM and Ansys Fluent software. 2.1.
2017-9-15 Grinding-induced subsurface damage (SSD) in silicon was evaluated by the model. • Ductile-regime effect, material anisotropy and degradation were influential to SSD. • SSD depths can be reduced by grinding along  direction or applying fluids. • The model can optimise silicon grinding to balance quality and grinding efficiency.
2019-7-24 In order to verify workpiece temperature and compare with numerical results due to the adopted source model, 3 thermocouples of K type with response time of 1 ms were positioned at 1 mm, 2 mm, and 3 mm below grinding surface and another one close to the workpiece surface, as will be explained (Fig. 3).
2017-3-8 Applied Mechanics in Grinding Part II 247 Umino et al. [24-30]. The former studied the relations between E and hg, while the latter discussed the
In this paper, a new model of cutting grinding force for disc wheels is presented. Initially, it was proposed that the grinding cutting force was formed by the grinding force and cutting force in combination. Considering the single-grit morphology, the single-grit average grinding
The proposed mathematical model can be used to calcu-late the profile data of the cone grinding wheel and the corresponding machine setup at a predetermined operating pitch cylinder.
4.3. Analysis of results for a precision grinding machine. In this study, the operating speed of the precision grinding machine was 15.000-26.000 rpm; therefore, model shapes from 250-500 Hz were discussed. For the given operating speed, the spindle head causes larger vibration than
