Process parameters are an important part of any quality control program. This is the process of measuring specific components of feed or ingredients at different stages like batching, grinding, mixing, conditioning, pelleting, cooling, crumbling, screening and packing.

Process control is an essential element of the quality management system, and refers to control of the activities employed in the handling of samples and examination processes in order to ensure accurate and reliable testing. Sample management, discussed in Chapter 5, and all quality control (QC) processes are a part of process control.

An effective method for grinding process control and quality inspection is the Barkhausen Noise method. This method was first discovered in 1919 and implemented to grinding quality control during the 1980s. It is sensitive to residual stresses and microstructure, which are directly involved with the grinding quality of the part.

Grinding Hub to highlight efficient fine machining processes. Unmanned production, 24/7. For many manufacturing companies, this is one of the key factors for success in this highly competitive field. This has been the case for turning, milling and drilling technologies for some time, but increasingly now also for fine machining.

The surface quality which can be achieved is very high, and grinding machines thus almost always find application in modern industry as a finishing process. Furthermore, through the increased performance of the grinding tools, grinding machines can now be used to achieve high material removal rates (Q'w [mm³/(mm*s)] during production grinding.

the quality of a product manufactured in a grinding machine, using the various quality improvement tools like Process monitoring techniques, Cause and Effect diagram, Why-Why analysis and Statistical Process Control Charts. The key note in using these tools is because of ease way to detect the problems and solutions for the same.

controlled temperatures, vary grinding speed, overcome product contamination, change media size and type, and get precise energy consumption information, all on the same machine. Results are repeatable from one test grind to another for maximum credibility. Finally, the Attritor is ideal for formulating, quality control, and scale-up studies.

Grinding is the preferred choice for finishing of automotive gears thanks to its high productivity and capability of machining heat-treated parts with very high geometric accuracy and surface quality. Grinding remains, however, the only machining process still to use lubricant, with significant costs, health implications and environmental risks.
