DESIGN AND ANALYSIS OF PEDAL DRILLING MACHINE AND DRILL BITS

Nowadays Power generation is a considerable one in our world. Small force operations are to be performed by manual power. Then only we Save the Electric energy. In this drilling machine we give power same as pedaling operation to get rotation of the drill bit. Sprockets are used to increase the speed of the drill. We can achieve different speed rate of spindle with respect to drive the pedaling force. Here power transmission losses are less due to use the chain drive. We can also do tapping operation, boring operation without changing of mechanisms except tool. Electrical input is also possible while we replace the pedal instead of motor shaft with coupling the manufacturing sector of India mainly depends on its productivity and quality. In many manufacturing activities is an ordinary operation that forms the main machining cost. With a slight improvement in drill bit geometric properties, we can minimize stress and improve the tool’s quality and life.
