Influence of milling parameters of powder DED Inconel 718 on cutting forces, surface roughness and temperature

Abstract. The influence of milling parameters is studied on Inconel 718 produced through Direct Energy Deposition powder (DED). Variations of two cutting parameters, cutting speed and feed rate, are considered for three environments, dry, wet and Micro Quantity Lubrication (MQL). During milling machining, cutting forces and temperature are measured while surface roughness is evaluated afterward. The Specific Cutting Energy (SCE) and the temperature slope were then considered. To map a large enough experimental domain, while reducing the number of experiments, a Design of Experiments (DOE) is adopted to assess the parameter influences. Feed rate is the more critical parameter while cutting speed influence fluctuates more according to the environment. Wet lubrication clearly stands out for reducing both Specific Cutting Energy and surface roughness. Meanwhile, MQL generates similar roughness and Specific Cutting Energy to dry condition but decreases more efficiently temperature growth slope. Fz= 0.13 mm/tooth and Vc= 50 m.min-1 are critical parameters inducing extremum values for all the output parameters.
