The CNC operates the interchangeable tools in the machine, telling the tool how many thousandths of an inch to move, drill, sand, cut, etc. at any given time. The instructions tell the machine how to move are entered into the CNC via an RS-232 or RS-422/485 stream from a PC. This eliminates costly errors caused by manually entering the data. The wrong instructions at any given time can scrap a huge piece of metal or break a very costly tool. When a PC has dozens of pages of instructions to deliver to a CNC it drip feeds it one line at a time because the CNC has a small memory buffer and overruns means dropped lines of instructions which means scrap metal or broken tools. Another pitfall to watch out for is when the CNC is paused the information from the PC needs to stop sending data right away. Otherwise when the CNC is restarted any lines of instructions sent during stoppage will not be re-sent. These dropped instructions result in errors in manufacturing.
