Gutakovskis et al. [17] were
performed turning test on AISI410 using nano coated cutting tool. Noordin et al. [18]
were conducted a dry turning test on AISI410 using coated cermets and coated carbide tool. Only limited number of research papers is available for turning of SS.
various compositions of cutting tools were used by the past researchers for turning.
But comparisons of single and multi-layered cutting tools for turning AISI316 and
AISI410 were not carried out by them.
Taguchi method is a powerful tool for the design of high quality systems. It
provides an efficient and systematic approach to optimize designs for
performance. Taguchi method is an efficient method for designing process that
operates consistently and optimally over a variety of conditions. To determine the
best design, it requires the use of a strategically designed experiment. Taguchi
approach to design of experiments is easy to adopt and apply to users with limited
knowledge of statistics, hence gained wide popularity in the engineering and
scientific community [19]. The desired cutting parameters are determined based
on experience or by handbook. Cutting parameters are reflected on surface
roughness, surface texture and dimensional deviation turned product [20]. In a
manufacturing process it is very important to achieve a consistent tolerance and
surface finish [21]. Taguchi method is especially suitable for industrial use, but
can also be used for scientific research [22]. In this investigation Taguchi
technique is used to determine
