Abstract

Abstract: The stacks structure composed of composite materials and metals has been widely used in the aerospace field, but drilling high-quality holes on composite/metal stacks structures remains a challenge. This article aims to investigate the influence of drilling process parameters on the axial force and surface quality of GFRP/Al stacks materials during drilling. The common carbide fried dough twists drill is used to drill the GFRP/Al stacks material “once”, and the drilling axial force is measured by the Kistler dynamometer. The results show that the maximum drilling axial force increases almost linearly with the increase of feed rate per revolution, and decreases slightly with the increase of spindle speed. The drilling process parameters affect the surface quality of aluminum alloy and GFRP hole making. High feed rate per revolution will reduce the burrs at the aluminum alloy hole making outlet, but it will increase the damage at the GFRP hole making outlet; high spindle speed will increase the burrs at the aluminum alloy hole outlet and damage at the GFRP hole outlet. Compared to the feed rate per revolution, the spindle speed has a greater impact on the quality of aluminum alloy and GFRP drilling.

Key words: GFRP/Al stacks material, drilling process parameters, drilling thrust force, drilling hole quality, composites
