Development of a new model for determine of cutting parameters in metal drilling processes
(Springer Heidelberg, 2020) Turkes, Erol; Erdem, Mehmet; Gök, Kadir; Gök, Arif
Metal drilling and cutting processes are used commonly in many areas of the industry. When these processes investigated analytically, it is seen that they have a very complicated structure. This complicated structure can find easy solutions with finite element-based simulation tools. In metal removal operations, it is very difficult to calculate the cutting parameters such as cutting tool stresses, residual stresses, cutting tool-chip interface temperature and shear angle both experimentally and analytically. But, these operations could be easily calculated by computer-supported simulation tools. In these types of numeric simulations, using finite element method, it is needed to identify clearly the friction, material model load and limiting conditions. In this paper, the cutting parameters as cutting and thrust power, heat transfer coefficient and friction coefficient at chip-tool interface which is needed to find the temperature distribution on drilling bit and workpiece material were calculated using analytic models.
