Abstract	The aim of the experimental investigations was to select the optimal proposed cutting tool geometry by studying the effects of the tool angles (tool back rake angle (γ p )) and the cutting edge angles (the tool cutting edge angle of the major cutting edge (κ r ) and cutting edge inclination angle (λ s )) and there interrelations, which produces less-generated cutting forces, less tool vibrations, and improved machined surface roughness for turning operations. Different cutting tool geometries were designed according to the main tool angles and manufactured with a high speed steel material (HSS) type-T15 with a high tungsten alloy grade. Based on measured cutting force components, tool vibrations, and surface roughness, it can be concluded that when the γ p angle ranges from a negative value (γ p = −5°) to a positive value (γ p = 0° and γ p = 5°), the average cutting force components decreased, especially tangential force component (Fz) that was more remarkable, and tool vibrations reduced; this decreasing trend improved surface roughness. The effects of the variation of the κ r angle and the positive λ s angle were observed on the variation of the axial and radial force component, whereas the tangential force remained constant. Lowering κ r decreased the surface roughness, while the λ s angle increased, a small variation was observed. As a conclusion, the good optimized cutting tool geometries were classified as follows: the first was cutting tool geometry having a neutral angle (γ p = 0°), the second was with γ p = +5°, and then the third was with γ p = −5°. Thereafter, the fourth tool geometry was having λ s = 3° and the last was for geometry having κ r = 75°.
