Abstract

Chip formation within a hole making processes plays an important role in selection of proper machining parameters. Understanding of this phenomenon is also important in relation to wear behaviour or machined surface integrity parameters like roughness, residual stresses and many others. Proposed study aims to compare different shapes and forms of chips produced when drilling titanium alloy Ti-6Al-4V with solid carbide tool by various cutting conditions. The effect of cutting edge radius and side clearance angle on chip formation process was also considered within this work. Experimental data has confirmed strong relationship between drilling parameters and evaluated variable.
