Experimental Analysis of the Cutting Force Components in Laser-Assisted Turning of Ti6Al4V

In this paper, the experimental analysis of the turning of Ti-6Al-4V titanium alloy with the laser-assisted machining was described. For the tests, a cemented carbide tool was used. The influence of the laser heating and cutting parameters on the tangential and thrust forces was determined. The beneficial effect of laser-assisted machining on components of the cutting force was established. Cutting force models were developed. The significant influence of interaction of cutting speed and laser power on tangential force components was observed. The microstructure of laser-scanned surface and the roughness parameters after turning as the process indicators connected with cutting force were analyzed.
