In my regression model I have four(04) input varibales (Al2O3, TiO2, Pressure, Speed) and there are one responce (Surface roughness(Ra)), So I don’t have idea how find optimum vales for four control factors to minimze the Surface roughness.
To develop this model I have done 16 experiments and the predicted values are shon below
Ra

Developed Regession Model
Ra = 28.66 + 50.01 Al2O3 + 35.80 TiO2 – 6.925 Pressure – 0.4221 Speed – 182.6 Al2O3*Al2O3 – 3.741 TiO2*TiO2 + 0.7566 Pressure*Pressure + 0.001753 Speed*Speed + 8.210 Al2O3*TiO2 – 2.541 Al2O3*Pressure – 0.04987 Al2O3*Speed – 3.373 TiO2*Pressure – 0.2407 TiO2*Speed + 0.03294 Pressure*Speed + 179.8 Al2O3*Al2O3*Al2O3
