Taguchi parametric study on the radial and tangential cutting forces in Dry High Speed Machining (DHSM)

In this paper, L8 Taguchi array is applied to find the most important parameter effects on the radial and tangential cutting forces of a Ti–6Al-4V ELI titanium alloy in dry high speed machining (DHSM). The experiments are performed in four cutting speeds of 150, 200, 250, and 300 m/min and two feed rates of 0.03 and 0.06 mm/rev. Also, two cutting tools in types of XOMX090308TR-ME06 of uncoated (H25) and TiAlN+TiN coated (F40M) are used. Results confirm that to minimize the resultant cutting force and radial cutting force, using the lower feed rate (0.03 mm/rev) and higher cutting speed (300 m/min) were considered as the best levels of studied factors.
