Machining Parameters

Surface roughness plays an important role in
deciding the quality of machining. Mathematical model has
been developed to predict the surface roughness in terms of
machining parameters such as helix angle of cutting tool,
spindle speed, feed rate, and depth of cut. Central composite
rotatable second order response surface methodology was
employed to create a mathematical model and the adequacy of
the model was verified using analysis of variance. The
experiments were conducted on stainless steel SS 202 by carbide
end mill cutter and the surface roughness was measured using
Mituotyo surface test SJ201. The direct and interaction effect of
the machining parameter with surface roughness were analyzed,
which helped to select process parameter in order to ensure
quality of end milling.
