Abstract
The constitution and fabrication of a bench shearing machine involved the design and assembly of various components to create a cutting tool with a stable base for industrial or workshop use. The project began with a comprehensive analysis of the requirements for a bench shearing machine, taking into consideration factors such as cutting capacity, material strength, and operational safety. The design phase included creating detailed drawings and specifications for each part of the machine, including the frame, blade, clamp, and handle. During the fabrication process, high-quality materials were selected to ensure durability and efficiency of the shearing machine. The frame was constructed using robust steel components to provide stability and support for the cutting mechanism. The blade was made from hardened steel to withstand the high forces applied during cutting operations, ensuring precise and clean cuts on various materials. The clamp mechanism was designed to securely hold the workpiece in place during cutting, preventing slippage and ensuring accurate cutting angles. The assembly of the bench shearing machine involved careful fitting and alignment of all components to ensure smooth operation and reliable performance. The blade was mounted securely to the frame, and the clamp mechanism was integrated to provide a secure grip on the workpiece. The handle was attached to facilitate easy operation and control of the cutting process, allowing the user to apply the necessary force to make clean cuts. The completed bench shearing machine demonstrated excellent cutting capabilities, with the ability to handle a wide range of materials including metals, plastics, and composites. The machine's sturdy construction and precise cutting mechanism made it suitable for various industrial applications, such as metalworking, fabrication, and woodworking. The ergonomic design of the handle and clamp mechanism ensured user comfort and safety during operation, reducing the risk of accidents or injuries. In conclusion, the constitution and fabrication of the bench shearing machine resulted in a high-quality cutting tool that meets the requirements of industrial and workshop settings. The project highlighted the importance of careful design and material selection in creating a durable and efficient machine for cutting various materials. The successful completion of the project provides a valuable contribution to the field of machine tool design and fabrication.

Thesis Overview

INTRODUCTION

Later in the years Nigeria as a country failed to react to the rapid advancement in technology until 1986, she realized that in both economy and technology she was under developed, she was dependent on the developed countries for survival, because many thing are being important from those countries. Attempt made to solve these problem include, introduction of the structural adjustment programme (SAP) and the war against indiscipline and corruption (WACI). These bodies prohibited the importation of some goods, there by building the inspiration on our people to embrace indigenous technology. This led to significant achievement in the field of technology of this country.
Since this great achievement has made engineer, scientist and technologist in this country were able to join efforts both mentally and manually into production and research programmes. One of the fruits of their contributed effort was the invention of the bench shearing machine.
The bench shearing machine is manually operated, it can be useful in work shops or factories.
In fact this product is aimed at providing a close substitute to the famous Japan made bench shearing machine.
It is worthy to note that this bench shearing machine is designed and fabricated using our locally available materials to show the important of copy technology.
PURPOSE OF THE PROJECT
The fabrication of bench shearing machine is to reduce, alleviate and to eliminate suffering, time, money, energy, and waste of material and more especially the need for technological break through and self reliance which has been major concern of the federal government.
Right from time immemorial metal shearing has been a very great problem in the society.
To help eradicate this problem this project write up has delved into simplicities and construction of bench shearing machine that can be use to cut up to 4mm sheet of mild steel plate with a treated blade made up of high carbon steel.
The machine is manually operated with handle known as the effort, the longer length of handle helps it to increase its output towards the work piece the material example mild steel, dead mild steel or aluminum alloys.
