In the area of conflict between an increasing demand for the surface finish quality of industrial components and a high degree of flexibility in process design, elastic grinding tool systems have been increasingly tried and tested in recent years. Process applications range from the high-precision structuring of tribologically stressed surfaces to the finishing of components such as shafts or turbines in large machine construction. Even though these tool systems have been used industrially for decades there is a lack of scientific knowledge about the non-linear process relationships as a result of elastic tool system deformation during the grinding process. Thus industrial potential remains unexploited. In contrast to grinding with bonded grinding wheels, it is generally assumed that the abrasive grains during elastic grinding can change both their orientation and their position depending on the elasticity of the tool system. The main objective of the planned research project is therefore to create new insights into how tool system deformation in belt grinding with an elastic contact roller affects the work results. As an application used frequently in industry, longitudinal surface belt grinding is selected to understand, in particular, the complex process interaction between the subsystems grinding belt and elastic contact roller and their influence on the work result as well as the cutting and wear behaviour. At the end of the project, a geometrical-kinematic process model will be available to quantify the influences of the tool system deformation on the resulting geometrical undeformed chip parameters. By means of this process model, a deeper understanding of the superimposed interrelationships for the material separation during elastic grinding should be achieved in order to contribute to an optimized design of elastic grinding processes.
