Abstract: This paper presents mathematical models for estimating torque, Rate of Penetration (ROP) as functions of cutting speed, flow rate, weight on bit and type of formation using factorial design of experiment technique for rock-drilling using Polycrystalline Diamond Compact (PDC) bits. The four factors corresponding to design parameters have been analysed simultaneously by main effects with two factor interactions. The developed model is tested for its adequacy using Analysis of Variance (ANOVA). The predicted results and trends of the factor interactions between the variables are presented, and found to be in good agreement with the results reported earlier.
