Multidisciplinary Simulation of Active Control of Machine-Tool Vibration in Turning

• The increasing computer power in modern manufacturing machines has given the possibility to integrate advanced computer based control systems. In this work a simulation model for active control of machine-tool vibration in turning operations is described. The model contains both the mechanical structure and the control system. The simulation is done with and without active control. The structure vibration is suppressed by simulating actuators. The simulation is done to get a first indication of the potentials of a proposed new tool holder design and to test the usability of such multidisciplinary simulations as a supporting tool for product development. The results show that it is possible to simulate the total system. The vibrations of the tool holder tip could be decreased significantly by using reasonable forces. The software used was found to be very user friendly and to be able to perform such coupled simulations in this way during product development must be considered to be a great advantage.

• En studie av potentialen för att använda multidisciplinära simuleringar har gjorts. Som tillämpning har en verktygshållare för svarvning använts.
