Process Control - an overview | ScienceDirect Topics

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 - an overview | ScienceDirect Topics

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.

Grinding Operation - an overview | ScienceDirect Topics

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.
