Prediction of Thrust Force in Twist Drill

Abstract

The present study is focused on predicting the thrust force in drilling with twist drill using finite element technique. The twist drill is versatile and can be used on a variety of materials. The approach is based on representing the cutting forces along the cutting lips as a series of oblique sections. For each section a Eulerian finite element method is used to simulate the cutting forces. The section forces were combined to predict the overall forces. A program in C language is developed using the above said approach. Thereafter it’s validation is done by experimental results given by Strenkowski et al. [13] where the same approach is being used. The values are calculated for machining of AISI 1020 steel.
