CNC Programming  

CNC stands for Computer Numerical Control which means a computer converts the design produced by Computer Aided Design software (CAD), into numbers and numbers can be considered to be the coordinates of a graph and they control the movement of the cutter. CNC machines are essential pieces of equipment in most modern factories, manufacturing plants, and machinist shops.

CNC programming is the creation of control programs for machines such as lathes, mills and other metalworking tools. CNC programming software is the creation of program codes and instructions used to run a machine tool controlled by a computer. CNC benefits include improved automation, consistent and accurate work pieces, and flexibility.

The professional in this field are known as a CNC Programmer who develop and run programs which direct the CNC machines to cut and shape metal or plastic for such things as airplanes, automobiles and other industrial machines. Programmer work includes loading and unloading work pieces, checking work pieces, setting program datum, setting up jigs and fixtures, replacing worn or broken tooling, cleaning the machine and basic machine maintenance.

CNC Programmers use blueprints and 3-dimensional computer designs to create the programs which result in cutting products. CNC operator varies from one machine shop to another and CNC operator writes the program that runs the machine by using software.

CNC programming requires technicians to use computers in order to control machine tools for the purpose of repeatedly manufacturing complex parts and using a program written in the complex G-Code notation, technicians ensure that all products adhere to the same precise measurements.
