Numerical Simulation on Diffusion Wear of Diamond Tool in Cutting of Ferrous Metals
The details of the process with respect to tool wear mechanisms in diamond cutting of ferrous metals are still not clear. For the sake of further studying on diffusion wear of diamond tool, as a consequence, the numerical simulation of diffusion process at interface of diamond and workpiece is presented based on Fick’s second law in this paper. The diffusion model of carbon atoms diffusion into γ-Fe has been established in terms of materials science theory. In addition, the distribution of carbon atoms concentration in regard to the variable of diffusion distance and diffusion time is calculated by numerical simulation, the tendency of concentration distribution is consistent with the results of previous studies. This work provides a basis research for diffusion wear in diamond cutting of ferrous metals.
