| Popis: | The nodular irons have more ductility which is demanded by mechanical components like crankshaft, cam shaft, bearing cap and clutch housing, offering fatigue resistance for their intended performance. The impact of various process parameters like depth of cut (D), cutting speed (S) and feed (F) on the cutting force of nodular iron was studied and optimized by using the RSM model. The nodular iron was turned at dry condition with two different types of cutting tools, namely CBN and coated tungsten carbide tool (TiCN + Al2O3 + TiN) to evaluate the influence of cutting parameters. The cutting speed employed for these tests are 102,174 and 245 m/min with feed rates of 0.051, 0.102 and 0.143 mm/rev together with the depth of cuts as 0.5, 0.75 and 1 mm. The tungsten carbide coated tool performed well as compared to CBN tool while machining with nodular iron in terms of getting lower cutting force and better surface roughness. |
