“Drilling and Tapping Machine: A Review”

This paper presents the fabrication analysis of the drilling and tapping process within an semi automated machine system, aimed at improving precision, efficiency, and reliability in machining operations. The analysis focuses on evaluating the critical aspects of material selection, tooling, machining techniques, and assembly methods involved in the fabrication of the drilling and tapping components. It examines the effects of material properties, cutting forces, and machining accuracy. Additionally, the paper addresses the optimization of the fabrication process by evaluating boundary conditions such as spindle speed, feed rates, and tool geometry to minimize errors, enhance surface finish, and extend tool life. The paper also outlines the key parts involved in the fabrication of the drilling and tapping system, including the spindle assembly, feed mechanism, tool holders, motor, and structural frame.
