Abstract: This paperwork presents some researches performed by the authors in the framework a national research grant regarding the retrofitting of a hob sharpening machine. The first step in this project was the identification of the movements involved in the process of hob sharpening, together with their kinematic dependencies. Because the references regarding these aspects are very poor and, furthermore, there is a very small number of hob sharpening machines in use these days, the process mentioned above was performed using simulation techniques. The known kinematic laws of motion and the shape of the imposed trajectory were combined into a simulation model in order to determine the unknown movements and the dependencies between them. After the simulation process, the structure of the retrofitted kinematic chains and the dependencies between the technological movements of the machine was determined.

 

Key words: hob sharpening, kinematic dependencies, laws of motion, simulation.
