Abstract
AbstractLapping and grinding are manufacturing processes which can be seen as a sequence of many single grain scratches. During grinding, the grains perform an oriented movement, whereas during lapping, the grains lie loosely in the gap between the lapping wheel and the workpiece while moving in a completely disordered manner. The Institute of Applied Structural Mechanics conducts experimental investigations and simulations to better understand the complex process. The goal is to develop a physical force model of the grinding and lapping process, by which process predictions can be made. For this purpose, finite element (FE) scratch simulations with geometrically simplified grains are carried out and the qualitative dependencies, such as the influence of the grain geometry and infeed on the stresses are examined.
