ABSTRACT
this paper presents a newly developed mathematical madeling for process parameters on drilling of medium density fiber board panel by carbide step drill,regression analysis and analysis of variance (ANOVA) is used to predict surface roughness and delamination.carbide step drills are used to drill the MDF panel to study the main and interaction effects of process parameters spindle speed feed rate and drill diameter a mathematical model to predict the responses viz surface roughness and delamination has been developed. the adequaies of the developed models are verified with R-squared value,
