The present work investigates the effect of cutting parameters (speed, feed and depth of cut) in Computer Numerical Control (CNC) turning of AA5052 aluminum alloy to achieve low surface roughness using tungsten carbide insert.
The experiments were designed according Taguchi’s L9 (3 levels*3 parameters) orthogonal array technique. Analysis of variance (ANOVA) was performed to find the significance of the cutting parameters on the surface roughness.
The results showed that feed and cutting speed are the most important parameters influencing the surface roughness .
From Taguchi analysis the minimum surface roughness are found at cutting speed of 900 rpm (Level 1), feed of 0.1 mm/rev (Level 1) and depth of cut of 0.5 mm (Level 1) respectively.
Thereafter, optimal range of surface roughness values was predicted.
Finally, the relationship between cutting parameters and response was developed using MINITAB-16 software and regression analysis has been done.
The predicted values were compared with the experimental values and it is observed that both values were very nearer and hence the models prepared were more accurate and adequate.
