Grinding Parameters | SpringerLink

For grinding processes the actuated variables (e.g., cutting speed, feed velocity) and the system variables (e.g., grinding tool properties) have to be distinguished from the grinding parameters. The grinding parameters depend on the actuated and system variables and allow a good correlation to the process forces, process temperatures, surface roughness, and grinding tool wear.
