Question 1

Discuss how technical information can conveyed.

Accepted Answer

Technical information about the shape and construction of a simple part may be conveyed from one person to another by the spoken or written word. As the addition of details makes the part or mechanism more complex, the designer, draftsperson, engineer, technician, and mechanic must use precise methods to describe the object adequately. Although a picture drawing or a photograph may be used to describe a part, neither method of representing an object shows the exact sizes, interior details, construction, or machining operations that are required. On the other hand, a drawing made accurately with instruments or produced by computer or a technical sketch meets the requirements for an accurate description of shape, construction, size, and other details.

Question 2

Explain CAD/CAM and how it is used.

Accepted Answer

Some industries tie their engineering and manufacturing departments together using a CAD/CAM linkup over a computer network. CAM stands for computer-aided manufacturing. In this process, the drafting department designs a product on a computer. After completion, the drawing is converted to coordinate data and then stored. Additional software called a post processor then converts the stored coordinate data into a usable format for the machines in the manufacturing department. Hardcopy is not produced unless someone needs to study the drawing away from a computer terminal.
