Design and Fabrication of Hand-Operated Pneumatic Hydraulic Metal Sheet Cutter

Abstract-In this project, a hand-operated hydraulic Metal Sheet cutter machine has been fabricated. A hydraulic jack is used as the hydraulic component here. The project was started to minimize the effort required in shearing metal sheets of various thicknesses compared to that required when using a simple hand-operated mechanical sheet cutter. The cutting of metal sheets is an essential process in various industries, but conventional cutting machines are often expensive, energy-intensive, and cumbersome to operate. This thesis presents the design and fabrication of a cost-effective, hand-operated hydraulic metal sheet cutter aimed at providing a simple yet efficient solution for small-scale industries and workshops. The device operates using a hydraulic mechanism, eliminating the need for electrical power, and can be manually operated with minimal physical effort. The cutter is designed to handle a range of metal sheet thicknesses, offering versatility while maintaining precision and durability. The design focused on optimizing the cutting force and mechanism to achieve high cutting efficiency with reduced human exertion. The project encompasses the entire development process, including the design calculations, material selection, and fabrication techniques. Performance tests were conducted to assess the functionality and efficiency of the cutter under various conditions. The results demonstrate that the hand-operated hydraulic cutter can effectively cut metal sheets with minimal deformation and high accuracy, making it a practical tool for small workshops or environments with limited resources. This study concludes that the developed system is not only economical and environmentally friendly but also provides an innovative alternative to conventional electrically powered cutting machines. Further optimization could potentially enhance its applications across various industries.
