used to set up a first process model that allows the modelling of the produced surface structures for path-controlled processes. For this purpose, sampled 3D surfaces of the honing tool and the workpiece surface were applied. By calculating the intersection height, the material removal was simulated depending on a predetermined depth of cut. Within the second project phase, it is intended to extend the current process model in order to simulate the workpiece surface generated by force-controlled honing processes. To accomplish this, detailed experiments have to be conducted dealing with the depth of indentation of the abrasives, the influence of the tool behavior in short-stroke honing and the composition of honing stones to achieve information about the effective material removal processes and mechanisms. This information will be transferred into the previously described force-controlled process model to considerably extend its reliability and accuracy. For the efficient analysis of the process, a special experimental setup is used to reduce the contact area between workpiece and tool. This decreases the complexity of the material removal and allows a more detailed investigation of the interactions between tool and workpiece.
