| Summary: | In this research paper, reliable mathematical model for estimating the cost of preheated end-milling of AISI D2 tool
steel using TiAlN coated carbide tool inserts is developed. Initially, the different components of machining cost
were identified, followed by establishment of equations to determine their values. Then, the required experimental
and non-experimental data were collected and the bottom-up approach was adopted for evaluating the cost of
machining corresponding to each of fifteen experimental runs. The Response Surface Methodology (RSM) was used
to develop the model in which the cost of machining is given as a function of the machining parameters; cutting
speed, feed per tooth, and preheating temperature, and expressed in RM per cm3. ANOVA output was utilized to
check the adequacy of the developed model. The developed model was found to be statistically adequate and this
was confirmed by the small prediction errors made by the model. |
