What is the definition of CNC Programming Software?

CNC programming software creates program codes and instructions used to run a machine tool controlled by a computer. Each unique part requires its own CNC program.
In general terms, CNC stands for Computer Numerical Control and has been around since the early 1970's (often referred to as NC programming). CNC has touched almost every form of manufacturing process. CNC machines typically replace (or work in conjunction with) some existing manufacturing process/es. CNC benefits include improved automation, consistent and accurate work pieces, and flexibility.

In modern CNC systems, end-to-end component design is highly automated using computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. The programs produce a computer file that is interpreted to extract the commands needed to operate a particular machine via a post processor, and then loaded into the CNC machines for production. Since any particular component might require the use of a number of different tools – drills, saws, etc., modern machines often combine multiple tools into a single "cell". In other installations, a number of different machines are used with an external controller and human or robotic operators that move the component from machine to machine. In either case, the series of steps needed to produce any part is highly automated and produces a part that closely matches the original CAD design.
