What Is Computer Numerical Control Programming

The first nc machines were built in the 1940s and 1950s based on existing tools that were modified with motors that moved the controls to follow points. Numerical control nc enables an operator to communicate with machine tools through a series of numbers and symbols.

Cnc machines require cnc professionals who can manage these industrial processes with todays state of the art cad technology.

What is computer numerical control programming. Numerical control also computer numerical control and commonly called cnc is the automated control of machining tools drills boring tools lathes and 3d printers by means of a computera cnc machine processes a piece of material metal plastic wood ceramic or composite to meet specifications by following a coded programmed instruction and without a manual operator. Hence the name numerical control is given to this type of programming. Nc stands for numerical control whereas cnc stands for computer numerical control. The history of numerical control nc began when the automation of machine tools first incorporated concepts of abstractly programmable logic and it continues today with the ongoing evolution of computer numerical control cnc technology. Computer numerical control or cnc systems are computer controlled machining tools used in manufacturing. The advantage to computer numerical control systems is the increased accuracy and processing speed for the production machines. Nc which quickly became computer numerical control cnc has brought tremendous changes to the metalworking industry. However cnc was not the first form of producing parts based on programming techniques. Computer numerical control cnc is an advanced form of computerized production and manufacturing. Both of these are automatic machines which are used for machining any metal with accurate dimensions. Part of smes fundamental manufacturing processes video series this program explains the basics of computer numerical control cnc by featuring segments on cnc principles and cnc programming. It is commonly used in manufacturing for machining metal and plastic parts. Computer numerical control cnc is a computer aided design cad protocol that converts spatial designs into a series of numbers. In other words the numerical control machine is defined as the machined that is controlled by the set of instructions called as the program. In numerical control method the numbers form the basic program instructions for different types of jobs.

Today we will discuss about difference between nc and cnc machine. Computer numerical control cnc is a method for automating control of machine tools through the use of software embedded in a microcomputer attached to the tool. The term numerical control is a widely accepted and commonly used term in the machine tool industry. It was actually preceded by nc or numerical control. In a cnc system there is a central computer processor used to interpret the specifications and direct the machine.
