in the industry because of several reasons including improved design quality, increased productivity, establishment of data base for manufacturing, creation of standards for design and doing away of inaccuracies brought about by hand-copying of several drafting as well as drawings’ inconsistency (Introduction to CAD, 2008).
CAM (Computer Aided Manufacturing) refers to the effective employment of the computer technology for manufacturing planning and control. CAM is concerned with manufacturing engineering processes including planning and scheduling of manufacturing processes, machining operations, control of quality of production processes and products as well as Numerical Control (NC) part programming. Computer-aided manufacturing is usually integrated with Computer Aided Design in CAD/CAM systems.
This allows movement of information from design section to product production planning with no need of entering the data manually on the part geometry(Introduction to CAD, 2008). CAM develops the information stored by CAD into information which is used as instructions for running and controlling production operations, machining, materials and equipment handling, product inspection and automatic testing.
The rationale for CAD/CAM comes out to justify improvements based on technology as far as manufacturing is concerned. This approach grows as a result of the need to make improvements on quality, productivity and product competitiveness. Other major reasons include: Better quality of the produced goods, better communication, higher production level, manufacturing common database, lowered prototype costs of construction and quicker customers’ response(Introduction to CAD, 2008).
The necessary hardware part for a CAD/CAM system includes components such as a digital computer, workstation, plotters and output put devices as well as storage devices. The system, in addition to this encompasses an interface communication which usually enables data transmission to other

It talks about the various scientific discoveries and developments which led to a more enriched life for man. Although there are different views about the effects of science on man, the advances in science are never-ending. Science still remains a powerful force in the development of the world’s culture.
The United States Military Academy (1817), now called Norwich University and Rensselaer Polytechnic Institute (1825) were the first schools to offer education in engineering in the United States. All along, science and mathematics have been the basis for mechanical engineering education (Burstall 200).
Engineering design has both aesthetic and functional elements which can be split in to the categories of system and product design (Dym & Little, 1999). The engineering design process is a sequence of steps that a designer follows when creating a new design or solving a problem.
Engineering drawing is referred to as a artistic piece of drawing that is created by any particular engineer who has obtained knowledge, skills and abilities (KSAs) in the field of engineering in order to be able to create drawings for the purpose of engineering.
Making material choice remains an essential element for enhancing proper functioning of the structure, upon construction. The selection process for materials follows analysis of the functions for the proposed structure being constructed. The functions determine the required material strength among other properties; hence selection of material meeting structural requirements (Jones 1975).
The utilisation of such materials dates back to many centuries, when Egyptian and Mesopotamian settlers began utilising a mixture of mud and straw in constructing durable houses (Seymour and Deanin 1987). These occurrences in 1500bc could be identified as the humble beginnings for composite development, as straw continued to be utilised in reinforcement of boats and pottery items.
It is recognized as one of the largest, oldest and broadest disciplines of engineering. Mechanical engineers generally use the principles of materials, energy and mechanics in the design, and manufacture
Mechanical engineers utilize the knowledge of the thermal environment and forces under which products operate in designing them for aesthetics, functionality, and capacity to withstand this environment and forces. The work of mechanical engineers is crucial in the making of
