Grinding Mechanics Microscale

Development of micro-grinding mechanics and machine tools

Micro-grinding with microscale machine tools is a micro-machining process in precision manufacturing of microscale parts such as micro sensors, micro actuators, micro fluidic devices, and micro machine parts. Mechanical micro-machining generally consists of various material removal processes. Micro-grinding of these processes is typically the final process step and it provides a competitive

On the mechanics of the grinding process Part I

Dec 01, 2003 Subsequently, Baker and Merchant investigated the basic mechanics of grinding. Most researchers considered the grinding process akin to milling process but on a microscale. They considered the cutting and thrust forces to be solely due to cutting and neglected the frictional rubbing forces on the clearance face of the grains.

Microscale Mechanical Behavior of the Subsurface by

Apr 25, 2005 With the nanoindentation method, mechanical behavior (nanohardness and modulus) at the microscale in subsurface was measured for AISI 52100 and AISI 1070 steel components machined by hard turning, grinding, and honing. The test results show that white layer increases nanohardness but decreases modulus of a turned surface.

Crystallographic Effects on Microscale Machining of

This paper studies the effects of crystallography on the microscale machining characteristics of polycrystalline brittle materials on a quantitative basis. It is believed that during micromachining of brittle materials, plastic deformation can occur at the tool-workpiece interface due to the presence of high compressive stresses which leads to

Surface Hardening: Hard Turning or Grinding? Gear

The grinding wheel is composed of many random irregular bonded abrasives, and therefore the machined surface has a random distribution of grinding marks. In contrast, hard turning is performed by a geometrically defined cutting edge, and therefore the feed marks have a uniform spacing determined by the prescribed feed rate.

Effects of Ball Size on the Grinding Behavior of Talc

The microscale group is not observed after 120 min of grinding, which indicates that talc powders are fully pulverized into sub-microscale after 120 min of grinding. However, re-aggregation occurred in some samples, and, thus, small amounts of ~4 and ~20 μm particles were observed after 120 min of grinding.
