The knowledge of the loads occurring during a manufacturing process is used in the concept of process signatures to optimize the manufacturing process and compare it with others. The prerequisite for this is that the loads can be characterized during the running process. Until now there is no in-process technique to measure the loads in the form of displacements and strains in the machined boundary zone. For this reason, the suitability of speckle photography is demonstrated for in-process measurements of material loads in a grinding process without cooling lubricant and the measurement results are compared with FEM simulations. As working hypothesis for the simulation it is assumed, that dry grinding is a purely thermally driven process. Despite the approximation by a purely thermal model with a constant heat source, the measurements are in good agreement with the simulation. View Paper here.
