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 [16-18].

seems essential. Micro-grinding provides a competitive edge in the fabrication of small-sized features and parts with superior surface quality compared with other processes. The quality aspects such as surface integrity of the parts produced by micro-grinding is influenced by various factors related to the

A process combining the micro-grinding and ultra-short pulsed laser ablation has been developed. The laser beam was used to remove material and create macro-structures on the surface of either the workpiece or grinding tool prior to the micro-grinding. The structured areas reduce the workpiece-tool contact area.
