Abstract :
Due to environmental effects of the wide use
of soluble, synthetic and semi synthetic cutting fluids and
the hazard involved in the use of these class of cutting
fluid, it has become necessary to find alternative cutting
fluid for machining operation. The use of biodegradable
oils has yielded positive result as they are
environmentally friendly and causes no hazard to
machinists. Taguchi DOE L9 (33
) orthogonal array was
used in this work to design the experiment and ANOVA
was used to analyze the result of formulated Neem oil
and Tamarind oil Cutting fluid. The investigation
comprised of Three (3) experimental groupings of nine
(9) experimental run of Neem, Tamarind and Mineral
cutting fluid turned mild Steels. The result clearly
indicated that Tamarind seed oil had the best surface
quality when used as cutting fluid and the smallest was
Mineral oil-based cutting fluid. The minimum surface
roughness was 3.142 for Tamarind, 3.842 for Neem and
5.46 for Mineral oil. The optimum cutting parameters
for the turning of mild steel was Spindle speed of 1700
rpm, Feed rate of 0.2mm/min and Depth of cut of 0.5
mm. The investigation from the contour plot reveals
thatrise in the Spindle speed decreases the surface
roughness of the mild steel. The temperature
measurement of the cutting zone reveals that experiment
4 had a cutting zone temperature of 36oC, Neem cutting
fluid had 39oC, Mineral cutting fluid had 39oC and dry
machining temperature was 49oC; Tamarind cutting oil
had percentage temperature reduction for the fourth
experiment run of 26.53%, Neem and Mineral cutting
fluid had the same percentage temperature reduction of
20.41%. Similar pattern was noticed for experiment run
8 where Tamarind had cutting zone temperature of
31oC, Neem cutting fluid 33oC, Mineral oil had cutting
zone temperature of 33oC and Dry machining cutting
zone temperature was at 40oC; The percentage
temperature reduction rate was 22.5% for Tamarind
cutting fluid, 17.5% for Neem and mineral oil cutting
fluid. The two cutting fluids from the investigation can
serve as a good alternative to mineral base cutting fluid.
