Thermo-Mechanical Analysis of Aluminium and Mild Steel during Friction Drilling

Abstract

Friction drilling is a non-machining method of making holes in metal, in which the material is melted by adding high pressure and friction energy. Friction drilling uses very heat resistant cemented carbide, pointed but not sharp object. This device is pressed against a target material with both high rotational speed and high pressure. The process reshapes all thematerial so that no material is lost. The sleeve that is about three times longer than the original diameter of the target material makes it possible to make very strong bolt joints in thin material. The objective of this paper is to study the thermo mechanical analysis of aluminium and mild steel during friction drilling, experimentally. The tool speed used is in therange of 2000 to 5000 rpm and feed rate in the range of 50 to 110 mm/min. Two different test materials, aluminium and MS-0.18C are used for investigation. Coupled field analysis is used to do analysis in Ansys. This study aims to provide deeper understanding of the frictiondrilling process.
