Abstract: In this article, two innovations for the simulation of inductive surface hardening processes are introduced. It is shown that numerical simulation is a valuable tool to support the process design of challenging problems. First, a 3 D model for the simulation of scan hardening processes for complex work pieces is presented. The focus in this section is on the concept of modelling. As an example, its application is shown for an inductor with a complex distribution of flux concentrators. The inductor is used for hardening an inner ring of a large bearing. By comparing the results of the simulation with experiments, the model is verified. In the second part of the paper, an inverse numerical calculation approach is introduced, which uses optimization algorithms. Based on the hardening pattern of a work piece, the dimensions and position of the inductor in relation to the work piece as well as the electrical parameters are calculated. A hollow shaft is presented as an example to show that effective process design is possible with the help of this approach.
