Comparison between Dynamic and Non-Dynamic Cutting Tool Option in FEM Simulation for Producing Dimple Structure

摘要

FEM simulation is known for its ability to simulate various cutting conditions in machining process and hence significantly reduce the number experimental trial to achieve the actual optimum cutting condition. This paper presents the capability of dynamic and non-dynamic cutting tool options that are available in the Third Wave AdvantEdge FEM software. The dynamic option was utilised for identifying the turning parameters for dimple structure fabrication and analysis of machining response such as cutting force and cutting temperature generated. The selected ranges of frequency which can be set in the dynamic assisted tooling for turning (DATT) along with other cutting parameters were simulated using dynamic cutting tool option resulted in stable wave shape that suitable for dimple fabrication. Furthermore, the simulation result also shows that cutting temperature and cutting force generated are smaller with a dynamic cutting tool than the non-dynamic cutting tool option. The dynamic cutting tool option in the Third Wave AdvantEdge was found to be very helpful and effective in determining a suitable range of cutting conditions and therefore, reducing the number of experiments for producing a dimple structure using the turning process.
