RESEARCH REGARDING THE DYNAMIC BEHAVIOUR OF AUTOMATIC TOOL FEEDING SYSTEMS FOR DIFFERENT TRANSITORY REGIMES.

The total machining time for a part produced on machining centers is influenced, besides the actual machining time, by the auxiliary times which include the automatic changing of the tools. In order to increase the productivity of machining centers, the research presented in this paper has focused on enhancing the movement speed of an automatic tool feeding system. Increasing the movement speed of the mechanism`s components has led to the appearance of unwanted side effects, such as shocks and vibrations. In order to minimize these effects, we have proposed and tested a new solution to adjust the braking regime. [ABSTRACT FROM AUTHOR]
