Project Abstract

Abstract
The project focuses on the design, construction, and testing of a bench shearing machine. The primary objective is to create a compact and efficient machine capable of cutting various materials with precision. The machine's constitution involves key components such as the frame, blade, lever arm, base plate, and handle. The frame provides structural support while the blade, made of high-grade steel, is responsible for the actual cutting process. The lever arm amplifies the force applied by the operator for cutting, ensuring ease of use. The base plate serves as the platform for materials to be cut, offering stability during the shearing process. The handle enables the user to operate the machine effectively. The fabrication process involves the selection of materials based on their strength, durability, and suitability for the intended purpose. The components are carefully assembled to ensure proper alignment and smooth operation. Precision cutting is achieved through the careful calibration of the blade and lever arm mechanism, allowing for consistent results across different materials. Testing of the machine involves cutting various materials such as metal sheets, plastic, and wood to evaluate its performance and accuracy. The results indicate that the bench shearing machine is capable of producing clean and precise cuts, meeting the desired specifications. Overall, the project demonstrates the successful constitution and fabrication of a bench shearing machine designed for versatility and efficiency in cutting various materials. The machine's compact design and user-friendly features make it suitable for a wide range of applications in workshops, fabrication units, and small-scale industries. The project contributes to the field of mechanical engineering by providing a practical solution for material cutting processes, showcasing the importance of precision engineering and innovative design in machine development. The bench shearing machine's construction and fabrication process highlight the importance of careful planning, attention to detail, and quality materials in creating a functional and reliable mechanical device. The project's success in achieving its objectives underscores the significance of practical hands-on projects in engineering education, allowing students to apply theoretical knowledge to real-world applications while fostering creativity and problem-solving skills.

Project 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.
