Know-how for modelling and simulating grind hardening process

University of Patras (UPATRAS) has concentrated the research effort in modelling and simulating grind hardening and grinding technologies. A detailed simulation model will allow the reduction of time and energy consuming set-up phases, the development of optimised cooling strategies and the selection of process parameters that will enable the best quality of the final part.

The main results that have been achieved during the project's duration:
1) Literature research on previous analytical conventional grinding simulation models.
2) Development of a simulation model for the prediction of hardness penetration depth (HPD) achieved from both dry and coolant fluid assisted grind hardening.
3) Realization of basic dry and wet grind hardening experiments and comparison with model's predictions. The investigated process parameters included the cutting depth and the grinding wheel peripheral speed.
4) Theoretical assessment of grinding wheel effect and comparison of the predictions with the experiments performed with TYROLIT's newly developed grinding wheels
5) Theoretical modelling of the development of residual stresses during the finish grinding processes that follow the grind hardening process
