A Definition:
Numerical Control is a system in which actions are controlled by the direct insertion of numerical data at some point. The system must automatically interpret at least some portion of the data
Types of Numerical Control
Conventional Numerical Control (NC)
Direct Numerical Control (DNC)
Computer Numerical Control (CNC)
Computer Numerical Control (CNC)
The idea of computer numerical control is to position a computer right at the machine tool. Most, if not all machine tools that are numericaly controlled are CNC machine tools.
Advantages
Reduces time for delivery of part Reduces scrap rate of material
Reduces tooling costs
Reduces layout time
Increases machine and tool life
Reduces storage problems
Less setup time
Reduces actual machining time Allows rapid design changes in part Less jigs and fixtures are needed
