A comparison between experimental data and predictions is made by combining the results from the micro-grinding force and temperature models. 2. Literature reviewMicro-grinding apparently resembles the conventional grinding process in terms of its …

2. Basic mechanism of micro-grinding Micro-grinding shares similar aspects of conventional grinding but it falls in the region of micro-machining because of size effects associated such as minimum chip thickness effect and tool edge radius effect. Size effect is defined as the increase in specific energy at low depth of cut and feed rate …

SiCp/Al composites contain fine reinforcing particles with high hardness and rigidity, which makes the processing more difficult. The surface roughness prediction model was established and the micro-grinding mechanism was revealed.
