| Numerical control, popularly known as the NC is very commonly used in machine tools. Numerical control is defined as the form of programmable automation, in which the process is controlled by the number, letters, and symbols. In the case of the machine tools this programmable automation is used for the operation of the machines.
In other words, the numerical control machine is defined as the machined that is controlled by the set of instructions called the program. In the numerical control method, the numbers form the basic program instructions for different types of jobs; hence the name numerical control is given to this type of programming. When the type of job changes, the program instructions of the job also change. It is easier to write new instructions for each job, hence NC provides lots of flexibility in its use. |
