CHAPTER ONE - [ Total Page(s): 4 ]CHAPTER ONE1.0 INTRODUCTION1.1 Importance of Sheet Metal Work and Bending MachineWhat is a metal? It is a strong shinny, which conducts electricity and melts when you make it hot enough. But surely metal must be something more than this because there are other substances such as carbon,, glass and rubbers, which are, obviously not metals but can also variously claim to have strength, elasticity or electrical conductivity.Furthermore, most of the metals will melt when heated sufficien ...

CHAPTER THREE - [ Total Page(s): 5 ]A little consideration will show that when a beam is subjected to the bending moment, the metal on the upper side of the beam will be shortened due to compression and those on the lower side will be elongated due to tension. It may be seen that somewhere between the top and bottom plane, there is a surface at which the metal s neither shortened nor lengthened. Such a surface is called “Neutral surface†The intersection of the neutral surface with any normal cross-section of the beam ... Continue reading---
CHAPTER FOUR - [ Total Page(s): 1 ]CHAPTER FOURCOMPONENT DESIGN AND CONSTRUCTION Sand casting is one of the quickest and most cost effective methods adopted in the production of metal prototypes and is an excellent solution for low to medium run of pasts that do not require a specific or precise shape repeatability. The summary of making a cast material using sand casting process are as follows.1. A mold was created by placing the mixture of sand, clay and water on a pattern, and when the pattern was removed ...

CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVE5.1 Analysis Every sector of the economy is experiencing changes. The production sector is not left out of the changes, infact it is more affected. Sheet metal today is used for doors, windows, frames, gates, etc.It’s worthy to mention, however that the road side welders have developed various ways of bending sheet metal manually, but most often, they generally have poor finishing. As a result, their output does not justify their effort or input.It could be said, that th ... Continue reading---
