Effect of Friction Drilling on Metallurgical and Mechanical Properties of Composite Materials: A Review

The objective of this study is to carry out a literature review on the effect of friction drilling parameters on the mechanical and metallurgical properties of materials. The friction drilling process uses heat generated by friction between the workpiece and the tool. In a single step, tool penetrates into the work material, forming a circular hole and forms bushing without generating chips. Bushing acts as a structural scaffold and guide to assemble sheet metal parts without the need for separate threaded parts. This review focuses on the basics of friction drilling, advantages, applications, metallurgical and mechanical properties of the tool and materials. Tools reviewed in this research are high speed steel (HSS) and AISI H13 chromium hot work steel. The study observes that coated friction drilling tool life is more than uncoated friction drilling tool. At higher spindle speed and feed rate, good quality hole is produced with maximum bushing height and better surface finish.
