3
Change
  • Technology has made advances in fabricating and
    design techniques that are clearly seen looking
    back through the history books

4
Prior to 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 4000BC-1800AD
Forming Processes
Hammering, Stamping, Casting
Joining Processes
Soldering, Riveting, Forge Welding, and Gluing
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
