- 3. INTRODUCTION • Computer Numerical Control (CNC) is one in which the functions and motions of a machine tool are controlled by means of a prepared program containing coded alphanumeric data. • CNC can control the motions of the workpiece or tool, the input parameters such as feed, depth of cut, speed, and the functions such as turning spindle on/off, turning coolant on/off.
- 4. HISTORY • The first commercial NC machines were built in the 1950's, and ran from punched tape. • In 1970 the first CNC machine is introduced with the advancement of following- a) Standard G-Code Language for Part Programs b) ComputerAided drawing c) Microcomputers
- 5. WORKING • CNC means Computer Numerical Control.This means a computer converts the design produced by ComputerAided Design software (CAD), into numbers. • The numbers can be considered to be the coordinates of a graph and they control the movement of the cutter. In this way the computer controls the cutting and shaping of the material. • G-code is a standardized programming language that many CNC machines understand. • A CNC system consists of three basic components- 1. Part program 2. Machine Control Unit (M.C.U) 3. Machine tool (lathe, drill press, milling machine etc)
- 10. APPLICATIONS • The applications of CNC include both for machine tool as well as non- machine tool areas.
