The document summarizes experimental research on friction drilling of aluminum and copper alloys using HSS and tungsten carbide tools. Friction drilling is a non-traditional hole making method that uses heat generated from friction between a rotating conical tool and workpiece to soften the material and form a hole. The research aims to study how the different thermal properties of aluminum and copper affect process parameters and hole/bushing quality measures like surface roughness and bushing height/thickness. Key findings are that materials with higher thermal conductivity require higher spindle speeds to dissipate heat, while lower conductivity materials perform better at lower speeds.
