Introduction- Background of Manufacturing:1. The Evolution of Product Realization (Ref: CAM by Chang)
Important inventions/ developments in Manufacturing (Chronologically-year wise)1770- Screw Cutting Lathe1775- Boring Mill1813- Interchangeability of Parts (Horse Pistols)1817- Planing Machine1845- Turret Lathe1847- Milling Machine (Brown & Sharp) for making Helical grooves in Twist Drills1900- High Speed Steel Tools (FW Taylor & M White)1952- Introduction of NC (Numerical Control)
2. Computers and their Evolution (From 1950)Silicon valley revolution- Solid state components- Diodes, TransistersLSI & VLSI Technology- leading to development of Microprocessors
Types of Computers- Micro ComputersMini ComputersMainframesSuper Computers
Hardware & Software development
3. HISTORY OF CAD/CAM (Ref: CAM by Chang-1.3)1950- MIT Milling Machine Project- Part Program prepared1955- MIT starts APT developer- ATC (Automatic Tool Changer) by IBM1960- Interactive Computer Graphics- CRT Display, Ist Industrial Robot, Adaptive Control1965- CNC, DNC concepts & Mini Computers, PLCs1985- Computer vision
4. Computer Aided Manufacturing: (Ref: CAD/CAM Practice & Applications- by P N Rao- 1.4)Manufacturing methods based on Production QuantityProductivity Vs Flexibility based on variety and volume
Accuracy- Close to targetPrecision- Consistently reproduced (Repeatability)
