Application of taguchi and box-behnken designs for surface roughness in precision grinding of silicon by Alao, Abdul-Raheed, Konneh, Mohamed

“…Taguchi method was used to study the effect and optimisation of grinding parameters while Box-Behnken method was utilised to develop a mathematical model relating the average surface roughness to the grinding parameters, depth of cut, feed rate and spindle speed. An orthogonal array (OA), the signal-to-noise (S/N) ratio, and the analysis of variance were employed to find the minimal surface roughness. …”
