Abstract
Cutting operations in workshops and fabrication shops often rely on manual hacksaws, which are labor-intensive and limited in consistency. Motorized alternatives improve speed, uniformity and operator comfort.
This project presents a Motorized Chain Mechanism Hacksaw that uses an electric motor coupled to a chain-and-sprocket drive. The rotary motion is transformed by a mechanical linkage into reciprocating motion of the blade, producing controlled and continuous cutting strokes.
The design is compact, economical and ideal for demonstrating power transmission, kinematics of mechanisms and practical fabrication skills to Mechanical Engineering students.
