1. History of Design

2. Drawing  A means for communication  Design is used to relay a visual concept Safety Proportion Line Quality Color Texture Efficiency Shape Durability Tolerance Functionality Maintenance Consideration Elements

3. Change  Technology has made advances in fabricating and design techniques that are clearly seen looking back through history

4. Before the Industrial Revolution  Cave men  Scratched symbols and scenes on cave walls providing us with a record of life and skills known during the Stone Age  The Oudea fortress  The first known floor plan of buildings to be constructed in an orderly fashion  Objects were handmade one at a time

5. Early Drafting Tools

6. Fabricating Techniques 4000 BC-1800 AD Hammering, Stamping, Casting Soldering, Riveting, Forge Welding, and Gluing Joining Processes Forming Processes Example of an early cast piece

7. Industrial Revolution  Parts were made in batches (1850)  Mass production (1900)  Need for interchanging parts  Measuring tools were developed  Profits  Efficient use of time and materials  Replacement parts were desired

8. Fabricating Techniques 1800AD-1900AD Electroplating, Steel Rolling Shaping, Milling Forming Processes Tools Example of milling

9. Fabricating Techniques 1900AD-1920AD Tube Rolling, Hot Extrusion Geared Lathes, Hobbing, High Speed, and Carbide Tools Forming Processes Tools Example of a geared lathe

10. Fabricating Techniques 1920AD-1970AD Powdered Metals, Electroforming, and Explosive Forming Numerical Control, Electrical and Chemical Machining, and Synthetic Diamond Forming Processes Tools Example of a CNC part

11. Fabricating Techniques 1970AD-2000AD Plastic Forming, Computer-Aided Design and Manufacturing, and Rapid Prototyping Coated Tools, Water Jet Machines, Electrical Discharge, Industrial Robots, Programmable Logic Controls, and Unattended Factories Forming Processes Tools Example of Stereolithography
