CNC, short for Computer Numerical Control, is not a familiar concept to most people. Only students of core engineering know the exact use and significance of CNC in the day to day life. An automated system of machine commands, CNC is an indispensable part of machining today. The existence of this technology shows the remarkable progress and advancement in the building up of infrastructure in the country.
CNC or Computer Numerical Control is an automated system that helps in commanding and controlling machine tools through the implementation of pre-programmed sequences of machine control commands. As opposed to being controlled manually, the CNC does not operate through the use of hand levers or wheels, or merely through mechanically automated cams.
The terminologies used most commonly with CNC is CAD or CAM. The design of a mechanical component in a modern CNC system and its manufacturing programs are highly automated. The definition of the mechanical dimensions of a machining part or component is done through CAD or Computer Aided Design; a software designed precisely for this purpose. This is then translated into manufacturing directives using another software called CAM or the Computer-aided Manufacturing software. A post-processing software also works on the results.
The uses of Computer Numerical Control in machining is multifarious and touches the basics of many industries. Here is a list of industries in which CNC is widely used:
