Analysis Pareto ANOVA

Pareto ANOVA analysis is an excellent tool for determining the contribution of each input parameter and their interactions with the output parameters (surface roughness). It is a simplified ANOVA analysis method that does not require an ANOVA table. Further details on Pareto ANOVA can be found in Park [12]. 

The Pareto ANOVA analysis for aluminum (AISI 6061) is given in Table 32.4. It shows that feed rate (B) has the most significant effect on surface roughness with a contribution ratio (P = 65%), followed by cutting speed (A) P = 9%), and depth of cut (C) (P S 3%). The interactions between cutting speed and feed rate (A x B) and feed rate and depth of cut (B x C) also played roles with contributing ratios P S 13%) and (P = 9%), respectively. It is worth pointing out that the total...

Taguchi also suggested the use of Pareto s ANOVA [12]. This technique does not require any statistical assumption so a statistical analysis of the responses cannot be performed. Figure 2.7 shows a Pareto s ANOVA table.
