Impact of Cutting Tool Geometric Parameters on Milling Titanium Alloy TC4
Abstract:
It’s very difficult to machine titanium alloy because of its features of small deformation coefficient, low thermal conductivity, small elastic modulus and large chemical activity. In this paper, we take titanium alloy TC4 as an example; using the finite element method (FEM) for the physical simulation of milling process, analyze the impact of some tool geometric parameters, such as rake angle, relief angle, rounded cutting edge radius etc., on chip form, cutting force, cutting temperature distribution of cutting tool and the maximum cutting temperature of rake face etc.. On this basis, we choose the best tool geometries, which can be taken as a theoretical reference for developing process plans of titanium alloy to reduce the number of tests and costs of field trials and to improve productivity.
