What is Numerical Control (NC)?
Numerical Control (NC) is the automated control of machining tools using a computer. NC is controlled by a set of instructions (program) in the form of numbers, letters and symbols.
What is Computer Numerical Control (CNC)?
A Computer Numerical Control (CNC) machine operates a portion of the material to meet specifications by adhering to the guided set of instructions (program) and without a manual administrator controlling the machining activity.
What are the major differences between NC and CNC?
Some major differences include the input method, ease of program modification, presence of memory to store instructions, cost, maintenance, flexibility, accuracy, and time consumption.
