Alloy

Three main manufacturing processes exist; formative, subtractive and additive processes. These manufacturing processes can be divided by the type of action or actions required to produce the final part. Formative processes form the material into the desired shape, either by using dies or moulds. Examples of formative processes are stamping, forging, drawing, rolling or extruding. Subtractive processes on the other hand remove layers of material to form the final part. Turning, milling, grinding,…

rivets or bonding. The volume between the spars is often used for storing fuel. An alternative to attaching stringers to the skin for stiffness is a machined skin, in which the skin, stringers and spar flanges can be machined from a single piece of alloy, called a billet. Advantages are that less riveting is required, resulting in a smoother surface, lighter and stronger structures are possible, construction faults are less likely, less maintenance is required and easy inspection is possible.…

1.2. Cones Speaker cones vary in size and shape as well as the material they are made of. They range from original Rice and Kellog design-paper cone, through Kevlar and carbon fibre, metal (aluminium) and a variety of composites, each manufacturer employing different materials suited to providing the best efficiency and linearity. First of all they wanted to achieve manufacturing consistency since wood is not a homogenous substance and tends to vary from one form of timber to another, even…

CHAPTER 1 INTRODUCTION 1.1 BACKGROUND The catalytic converter was invented by Eugene Houdry, a French mechanical engineer and skilled in catalytic oil refining who lived in the United States around 1950. The invention of catalytic converter has a major role in controlling harmful emissions. When the paper of smog in Los Angeles was published, Houdry became anxious about the role of smoke stack and automobile exhaust in air pollution and established a company, Oxy-Catalyst. Houdry primary…

Being a dominate player in the auto business for over a century, Ford Motors have been reluctant to keep up with current trends and evolving competitors from growing economies. This has forced Ford to take dramatic measures by cutting jobs and closing a large numbers of its manufacturing facilities. Considering the company’s external and internal opportunities, and directing their resources towards a more skillfully R& D (research and development) department would be the first step to recovering…

The truth of the matter is that most of these accidents are avoidable, here's how to properly fix auto…

dollar funds from Chinese banks to make the acquisition in cash if required. Because SZLN had raised approximately US$90 million equity funds in late 2006 and had accumulated profits in 2006 and 2007, its liabilities–assets ratio had decreased from approximately 70 per cent to 50 per cent over the 2006-2007 period. This financial slack provided the company with a degree of flexibility to take on this opportunity. Nevertheless, the future cash needs of PEM would need to be considered before…
