OPTIMIZATION OF PROCESS PARAMETERS IN DRILLING OPERATION USING TAGUCHI METHOD

Abstract

Drilling can be described as a process where a multi-point tool is used to remove unwanted materials to produce a desired hole. It broadly covers those methods used for producing cylindrical holes in the work piece. In this study, the basic aim was to find optimal parameter in drilling to minimise the value of thrust and torque and to compare the same between Al-6061 and Mild steel. In this study specimen of Mild steel and Al-6061 of height (70mm) and diameter (40mm). Taguchi was used as the optimization technique. The experiment was performed by taking the three factors each having 3 levels. Based on the sequence, drilling was done by taking HSS drill bit of different size diameter. In particular, it is found that high speed and low feed and small diameter is giving a better result having low torque and thrust and the value of thrust and torque is more for mild steel.
