W. Brian Rowe, in Principles of Modern Grinding Technology, 2009. Intelligent Control. Intelligent control is where the CNC can change an input process control parameter it has been given to improve process operation. An example of intelligent control is where the feed position for final size is changed in response to a sensor measurement such as a diameter gauge.

The grinding process is hard to observe directly due to its short contact time and small contact zone. Therefore, analyzing cutting forces and chip formation mechanisms can help to understand the grinding process better. The topography of abrasive material and kinematic motion between wheel-workpiece interfaces control the cutting forces.

Abrasive machining processes are impacting the product performance heavily because they are usually performed at the end of process chains. Therefore, the sustainability of abrasive processes has to be discussed thoroughly [3,4]. Unit process life cycle inventories (UPLCI) provide a powerful means to describe environmental impacts [5].
Conventional Grinding. Conventional grinding takes place in tumbling mills where the ore is introduced into a horizontal mill where the cylindrical body of the mill is turned by a motor, causing the mill charge of ore and grinding media to tumble.

For surface grinding operations, the process parameters, i.e. the linear feed, the cross feed, and the depth of cut, have a direct influence on the roughness of the ground surface.Higher values of any of them would result in a higher material removal rate, and therefore, a higher rate of generation of thermal energy.
Tool grinding is an essential process for the production of cemented carbide tools. In that context, the investigation of specific effects like the resulting surface profile and the fluid dynamic processes is of great interest, but requires microscopic modeling of the grinding wheel including its individual grains and bonding material.
Applications of grinding processes for composites. Fiber-reinforced polymeric composites are currently very popular in fabricating a diverse group of products. Those include boats, skiing gear, water surfing boards, masts, construction panels and the like. Such applications do not require that such parts be produced with tight tolerances.

processes mostly used to manufacture micro and intricate parts. But they are only used for mass production due to higher setup cost. In this context, micro-grinding is expected to provide an alternative to LIGA and FIB [1]. Micro-grinding has a competitive edge over other micro fabrication processes as it is generally used as a finishing process
In this paper, the nanogrinding process of single-crystal silicon carbide is studied with molecular dynamics. By changing the grinding depth, we analyze the atomic Y direction displacement, crystal defect, force, von Mises stress and the wear of abrasive. We found that with the increase in grinding depth, the atomic Y direction displacement, crystal defect, force and …

traverse grinding process entailing a 1-D dexel representation of wheel and workpiece (inspired by [6]). Discussion and conclusions are developed in Section 4. 2. Modeling approach When considering the mechanics of grinding, several physical quantities have to be modeled, each one having effect on the resulting grinding forces, wheel and workpiece
behaviour of grinding machine towards these aspects is very important. A typical grinding machine consists of work piece-roll (metal) and grinding wheel (stone) which keep contact interaction during the process. The contact vibration problem of such kind of system is studied in this work. In order to ensure the finishing the

Moreover, the ever expanding use of CNC grinding machines in the industrial sector makes it increasingly necessary to study the process as it pertains to
Kinematics. Grinding wheel. Grain size. Microrelief. Surface working layer. 1. Main text. The main characteristics of formation of microrelief of work surface of the wheel depend on the law of difference in altitude of cutting edges and corner radiuses of their tops. In general, cutting edges of a wheel are expressed as a random variable.
