Abstract

Due to their excellent comprehensive characteristics, titanium alloys have found widespread applications. Nonetheless, they are considered to be challenging for machines. The aims of manufacturing and processing are high efficiency, minimal cost, and high quality, while cutting parameters are crucial factors that influence the machining process. This manuscript focuses on optimizing cutting parameters for machining titanium alloys. High-speed dry milling was carried out on Ti6Al4V titanium alloy using coated carbide tools on a HASSVF3SS machining center. An orthogonal experiment featuring four factors, each with four levels, was designed to analyze surface roughness and cutting forces under varied milling parameters. The regression analysis results show that the main factors influencing milling force are axial cutting depth, cutting speed, and feed, with R2 = 0.9883, 0.9757, and 0.8854, respectively. Meanwhile, radial cut depth significantly influences surface roughness, with R2 = 0.6559. Using one-way Analysis of Variance to control the two aspects of cutting force and surface roughness, the optimal milling parameter is as follows: 0.1 mm axial cut depth, 90 m/min milling speed, 0.13 mm feed, and 6 mm radial cut depth.
