Modelling and Simulation of Grinding Processes

Abstract This paper describes the state-of-the-art in the modelling and simulation of grinding processes. The kinematics of the grinding process are characterised by a series of statistically irregular and separate engagements. Topography models are used to describe the structure of the grinding wheel, taking the quantities of motion and the geometric parameters into account. Chip formation is represented in chip thickness models. During the process of chip formation, energy is transformed. Additionally, forces are generated. In this paper, grinding energy models and force models will be presented. In conclusion, the kinematic and energetic processes are taken into consideration for temperature and surface integrity models as well as for models for describing the surface roughness of the workpiece. Different approaches to modelling will be compared. Furthermore, the benefits as well as the limits of model application and simulation will be discussed.
