“…Taguchi's approach to design of experiments is easy to be adopted and applyed for users with limited knowledge of statistics; hence it has gained a wide popularity in the engineering and scientific community. There have been plenty of recent applications of Taguchi techniques to materials processing for process optimization; some of the previous works are listed in references (Yang; Tarng, 1998) (Su et al, 1999) (Nian et al, 1999) (Lin, 2002) (Davim, 2003) (Ghani et al, 2004). In particular, it is recommended analyzing metal cutting problems to find the optimal combination of parameters (Ghani et al, 2004).…”
