Abstract

Abstract

Nickel-based superalloy Inconel718 can maintain excellent mechanical properties at high temperatures above 600 ℃, so it is widely used in aerospace and other important scientific and industrial fields. It is a difficult-to-process material for situations of large drilling force, high temperature in drilling area and large tool wear during drilling process. A step drill was designed based on twist drill and the concept of diameter ratio (the ratio of the diameter of the first step to the second step) was introduced, and finite element simulations of Inconel718 drilling with two kinds of drill bits were carried out by using Deform−3D software. The results show that the step drilling can reduce the axial force by 25.5% on average compared with twist drilling, the maximum tool wear can reduced by 33.9%, the temperature of the workpiece drilling area was more lower and the bit temperature distribution under the same drilling environment was more better.
