Performance of Carbide Tools with Micro-Texture on Titanium Alloys Cutting in Dry Conditions

Abstract:

Article Preview

Hard machinability of titanium alloys severely limits its development in the field of aviation. It has been proved that micro-texture has a good effect on friction-reducing in turning under the conditions of Minimum Quantity Lubrication (MQL). In this paper, cutting tool with micro-texture on its rake face is fabricated and then experiments are carried out under the conditions of dry continuous turning titanium alloys. A dynamometer is set under the workpiece to measure three components of the cutting forces and the data is processed by Business software MATLAB. Average coefficient μ is calculated according to the mechanical model. Experimental results show that under the dry conditions, micro-texture plays a role in the specific cutting parameters while losing its role in most cases. Also the reasons which lead to the failure of improving the friction properties are analyzed.
