Performance of the machining and the efficiency of milling
operation depend on several process variables among which hardness of work
material is of great significant. The use of cutting fluids is an important
part of a machining process system. Without cutting fluid, tools have only a
short life, which makes the machining process costly. In this study,
experimentation was carried out to investigate the effect of work hardness on
end milling process. Workpiece material hardness is used as a noise factor. Input
parameters used are spindle speed, feed; depth of cut and tool diameter. The
experiments performed under wet and minimum Quantity lubrication and results of
both compared. further for getting optimal lubricant conditions the experiments
performed for various levels of flow rates of minimum quantity lubrication to
get the best optimal setting. Taguchi method is used for single objective
optimization. The S/N is used by Taguchi approach to analyze experimental data.
Output parameters are surface roughness, material removal rate, cutting force
and tool wear. Design of Experiment (DOE) with Taguchi L27 Orthogonal Array
(OA) has been explored to produce 27 specimens on Al2024 aluminium by end
milling operation at three different levels of hardness of material. The
present study can be used for implementing the Minimum Quantity Lubrication
Technique in place of conventional Wet Lubrication. The experiments performed
under wet and minimum quantity lubrication condition and results compared.
Further For optimal lubricant condition the experiments performed at various
flow rate of Minimum Quantity Lubrication and “best” optimal setting is
identified.
