Abstract

Several researchers have explored innovations in motorized and automated hacksaw machines to enhanced productivity, reduce manual effort, and lower operational costs. Motorized metal cutter is a type of machine tool design for cutting material pieces with precision and efficiency. It uses a powered saw blade to make straight cuts, replacing manual hacksaw. This machine can solve the problem of time consumption. This system involves creating a motorized metal cutter employing simple mechanical components such as a V-belt, pulleys, rollers, pillow block ball bearings, and a shaft. The machine helps to cut metal rods, pipes, and bars with ease and speed compared to manual cutting. An electric motor powers the mechanism through a V-belt and pulley that turns a pillow block bearing-supported shaft. This rotation is then converted to back-and-forth motion with the help of a roller mechanism, enabling the hacksaw blade to cut through the material. The mechanism is simple, economical, and requires less maintenance, thus being convenient for small-scale workshops and fabrication units. The calculated values for the tension of the belt T1=258N (tension side), T2=85.80N (slack side), T3= 737.53N (tension side) & T4 = 246.75N (slack side), power of the motor as 746 RPM, torque as 45.1Nm and the length of the belt from motor pulley to shaft pulley is 1008.21mm & the length of the smaller pulley on the same shaft to the crank pulley is 884.43mm .The system demonstrates about utilization of universal mechanical components in creating an effective cutting machine.
