Abstract
This paper mainly focuses on the drilling
parameter optimization by introducing Response Surface
Methodology (RSM). RSM is the most effective methods
to modeling and find optimum results. In this study, three
parameters such as cutting speed, feed rate and point
angle has been selected as input parameters and surface
roughness, torque, thrust force and material removal
rate (MRR) are taken as the responses. The experiments
are carried out over the AISI 429 steel plate with the
dimension of 100×100×10 mm by using HSS 8 mm drill
bit. The input parameters are predicted by using response
surface methodology (RSM). From the results that can be
observed clearly the predicted parameters speed and feed
rate are the most important to get good surface integrity
and maximum material removal rate.
