(PDF) State of the Art of Micro turning Process
Micro turning is one type of micromachining process which uses a solid tool and its material removal process is almost similar to conventional turning operation.Grinding is the common collective name for machining processes that utilize hard, abrasive particles as the cutting medium. The grinding process of shaping materials is probably the oldest in existence, dating from the time prehistoric humans found that they could sharpen their tools by rubbing them against gritty rocks.Grinding Processes SpringerLink

Optimization of micro-grinding process with compressed air
This paper addresses the optimization of a micro-grinding process using compressed air to minimize specific grinding forces and surface roughness while maximizing specific material removal rate (MRR). The design-of-experiments (DOE) approach and response surface methodology (RSM) are introduced to obtain the optimal However, in laser-assisted micro-grinding of Si 3 N 4 and Al 2 O 3, grinding depth and force are almost the same as those in conventional micro-grinding process [92]. The disadvantage of laser-assisted micro-machining is that burr heights increase due to thermal softening of the workpiece.Hybrid micro-machining processes: A review ScienceDirect

The effects of grinding process parameters of a cemented carbide micro
The structure of the micro-drill head is complex. The head is composed of four surfaces: two first flanks B 1 and B 2, which are at 15° to the end plane and two second flanks A 1 and A 2 which are at 30° to the end plane of the micro-drill head (Fig. 2).This complex spatial structure is generated generally by two grinding wheels which are Micro-milling is a mechanical machining process that uses miniature tools rotating at extremely high speeds to remove unwanted material from a workpiece’s surface.
