Abstract
Power hacksaws are essential in workshops for cutting metal stock. Conventional motor-driven machines are effective but can be bulky and require electrical power. A pneumatic alternative offers clean operation, overload protection and suitability for environments where compressed air is already available.
This project designs and fabricates a pneumatic reciprocating power hacksaw consisting of a double-acting cylinder, directional control valve, pressure regulator, rigid frame, blade holder and work-holding vice. Air pressure drives the blade in a continuous reciprocating motion, enabling efficient cutting of mild-steel bars and pipes.
It is an excellent final-year project for Mechanical and Mechatronics students, combining pneumatic circuit design, structural fabrication and practical machining application.
