abstract

The effect of tool geometry on the quality of the machined part has been an important consideration. Here the effect of tool geometry from energy minimization angle has been studied for sustainable manufacturing. The greenhouse gas (GHG) emission has been analyzed in terms of rake angle (α) and shear plane angle (φ). A numerical study of tool geometry and its effect on eco-indicators has been presented. The shear force (Fs) decreases as rake angle increases. The reduction in horse power requirement will affect the GHG emissions. It has been quantified how much CO2 is emitted in air during machining. The other toxic gases like NOx, SO2, CH4, and mercury (Hg) emissions have also been quantified. The friction force (F) declines very rapidly as rake angle (α) increases and reduce the lubricant requirement. The total specific energy (TSE) is summation of specific process energy (SPE) and specific constant energy (SCE).
