The comparison experiment between micro-grinding and micro-milling has been carried out on the micro-machining test-bed developed by Northeast University. Wear of the grinding pin obtained from experiment is considered to provide the basis for the micro-machining system and fabricating of grinding pins. Access through your institution Add to Cart
Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.
In the micro grinding process, geometrically deviated structures are common due to the low depth of cuts compared to the size of abrasive grits. Moreover, abrasive grits random distribution on the tool surface is also a factor. In most of the cases, the number of grits participating in the grinding process is countable, unlike macro grinding ...
The aim of this thesis is to advance a fundamental understanding of process mechanics and surface integrity in micro-grinding of advanced materials, such as additively and conventionally manufactured titanium and engineering ceramic. Grinding forces and specific grinding energy were chosen as the two most important indicators to investigate the process.

Grinding wheels come in many different sizes, shapes, and abrasives (Figure 5-7). Some of the various types are listed below. Straight Straight wheels, numbers 1, 5, and 7, are commonly applied to internal, cylindrical, horizontal spindle, surface, tool, and offhand grinding and snagging. The recesses in type
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

However, it is a difficult task to establish a comprehensive grinding force model that takes into account the brittle fracture, grinding conditions, and random distribution of the grinding wheel topography. Therefore, this study developed a new grinding force model for micro-grinding of reaction-bonded silicon carbide (RB-SiC) ceramics.
