ABSTRACT This project is on the design and construction of an automatic power hacksaw machine for cutting of metal to different size and length with the help of hacksaw. The objective of this project is to save man power and time in cutting metals in order to achieve high productivity. It is a cutting machine with teeth on its blade used specially for cutting metals. The power to the hacksaw is provided by the motors. The motor drives the pulley-1 connected to the rotor of the motor. The pulley -1 to the flywheel-1 by belt drive. The flywheel -1 is coupled to the one end of shaft-1 and the other end of shaft -1 is coupled to the pulley-2. Again pulley -2 is connected to the flywheel -2 by belt drive. Flywheel-2 is coupled to the one end of shaft -2 and the other end of shaft-2 the crank which is turn is connected to the connecting rod is connected to the vertical arm connected to the horizontal arm. Rotary motion of the shaft is converted into reciprocating motion of the hacksaw with the help of shaft and pulley. Work piece of desired length be cut by feeding it to hacksaw by holding it into bench vice. The various component of the machine were designed and constructed. Test was carried out on the machine using different metals.
