What is CNC ? |
 |
Computer numerical control (CNC) is the numerical control system in which a dedicated, stored
program computer is built into the control to perform basic and advanced NC functions. The control signals in CNC systems are in the form of binary words. Each word contains a
fixed number of bits, 32 bits or 64 bits are commonly used. Each bit of data produces one BLU motion in
the controlled axis. Theoretically a 32-bit word could represent one of up to 232 = 4,294,967,296 different
axial positions. If the system resolution is, for example, BLU = 0.0001, this number can represent
up to 429,969 possible motions, which is more than enough for all types of applications.
