There are three important components of the NC system or NC Machine tool. These are: 1) Program of instructions, 2) Controller unit, also called as the machine control unit (MCU) and 3) Machine tool. The program of instructions of the NC machine is the step-by-step set of instructions that tells the machines what it has to do.

UNIT 1 INTRODUCTION TO NC MACHINE Introduction

2011-3-28  Controlling a machine tool by means of prepared program, which consists of blocks, or series of numbers, is know as numerical control (NC). In manufacturing of more complicated parts, the system has to calculate automatically additional data points, which is done by means of an interpolator. Numerical Control (NC) refers to the method of controlling the manufacturing operation by means of directly inserted coded numerical instructions into the machine tool. It is important to realize that NC is not a machining method; rather, it is a concept of machine control. Although the most popular applications of NC are in machining, NC
