| Objective: | Goal of the research project is to computationally predict the flank topology of bevel or hypoid gears resulting from lapping. |
| Approach: |
The lapping process is discretized temporally. Starting from an initial geometry, the local variables (stress, contact distance, sliding velocity) are obtained by a tooth contact simulation and supplied to an abrasive wear approach to calculate the local wear depth. The flank geometry is modified accordingly for the next calculation step. At the end of the process, the simulation yields the local wear depth for any point of the tooth flank. |
| Results: | The project’s result is a simulation software that predicts the local wear depth distribution as well as an additional program for the experimental determination of the necessary process and material parameters. Lapping programs can now be created based on an objective repeatable process instead of practical knowledge and extensive tests, offering the possibility of a closed-loop process in the future. |
