How Does CNC Programming Control CNC Machines?
Before the advent of computers, machinists used cards or tapes to control machine movements. They punched holes in these cards in a specific order to create the codes. While this was also effective at the time, it was quite tedious. Also, these cards were prone to damage or getting lost in the machine shops. This led to several problems in production at the time.
When machinists started using computers for numerically controlled machines, they still came across a few problems. This was because they had to input the codes manually. This would, of course, be very tedious when they were making quite sophisticated parts that required a lot of instructions.
