To study the effect of cutting fluid concentration and cutting parameters on surface roughness of steel after turning

In present industrial era, strict tolerance limits are used in manufacturing parts that require higher surface finish and the given work laid emphasis on optimizing the surface roughness of AISI 1030 steel during wet CNC turning operation. The main purpose of this experimental investigationis to analyse the effect of cutting parameters such as cutting speed, feed rate, depth of cut, cutting fluid concentration and two cutting fluids with different base oils on surface roughness (Ra) on AISI 1030 steel during turning operation. The design of experiments, custom design method, and Taughci method are used to achieve this objective. The analysis reveals that feed rate has the most significant effect on surface roughness (Ra) and value of surface roughness does not significantly differ for two different cutting fluids used.
