Prediction of cutting forces in drilling of aluminum 6061-T6 alloy

Abstract

Drilling is the most common machining operation and arguably the most crucial of the traditional machining processes. Cutting force predictions for every given set of cutting conditions are crucial for efficient product development. It has been hypothesized that the force produced during cutting is responsible for the majority of the issues seen in hole creating processes like drilling. Calculating forces accurately also aids in the development and assessment of cutting equipment and fixtures. The purpose of this article is to examine the effect of significant machining factors like thrust force and torque on the drilling operations of Aluminum 6061-T6 alloy. Theory and experiment will be compared with different types of drill bits. An average error of 5.81% was found in the Axial Force (N) and 0.85% was observed in Torque (N-cm). The error % of desired responses is found to be accepted.
