Thesis Abstract

Abstract
This research project focuses on the design, construction, and testing of a bench shearing machine. The primary aim of this study is to develop a compact and efficient bench shearing machine that can be used for cutting various materials such as metal sheets, plastics, and other similar materials. The machine is designed to be user-friendly, safe, and cost-effective for small-scale industrial applications and workshops. The project begins with a comprehensive review of existing bench shearing machines to identify their key components, working principles, and limitations. Based on this review, a novel design is proposed, taking into consideration factors such as cutting capacity, blade material, force transmission, and overall machine dimensions. The design incorporates a sturdy frame, a lever-operated cutting mechanism, and a safety guard to prevent accidents during operation. The fabrication process involves sourcing high-quality materials for the frame, blades, and other critical components. The assembly of the machine requires precision in aligning the blades and adjusting the cutting clearance to ensure accurate and clean cuts. The project also explores different methods of blade sharpening and maintenance to prolong the machine's lifespan and optimize cutting performance. After the fabrication is complete, the machine undergoes rigorous testing to evaluate its cutting capacity, precision, and safety features. Various materials with different thicknesses are used to test the machine's performance under different cutting conditions. The results are analyzed to assess the machine's efficiency and to identify areas for potential improvement. Overall, this research project contributes to the field of manufacturing technology by providing a detailed insight into the design, fabrication, and testing processes involved in creating a bench shearing machine. The project highlights the importance of considering factors such as material selection, machine ergonomics, and safety features in the development of industrial machinery. The findings of this study can be valuable for engineers, manufacturers, and workshop owners looking to enhance their cutting processes and improve productivity in their operations.

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.
