Definition

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. The most important grinding parameters, that are described here, are the material removal rate Q_w, the material removal rate per unit active grinding wheel width Q′_w, the geometrical contact length l_g, the kinematic contact length l_k, the equivalent chip thickness h_eq, and the medium single-grain chip thickness h_cu.

Theory and Application

Introduction

The grinding process is a geometrically undefined cutting process due to the undefined number and geometry of cutting edges interacting with the workpiece. The load on the workpiece as...
