Programming is a key aspect of CNC machine. Programming is carried out by human. CNC machineries cannot be carried out without codes.

The language used to describe CNC machining is also known as G-Code. The majority of manufacturing machines use code that can be used to control the operation of one or two. G-Code is more complex than this.

G-Code is able to control a variety of actions of CNC machines. They include feed rate, and coordination.

Once G-Code is written and fed into the machine, there's almost no need for human operators. The code does most (if not all) of the work. https://diesandinc.com/
