CNC Stands for Computer Numeric Controlled in the Machining industry. It is the only way to go, as it is the easiest and fastest way to machine parts. Manual machining is virtually extinct in the industry today, and NC is too outdated by today’s competitive standards. CNC is better because you can write and edit programs in the machine’s controller, giving you complete control of how it runs. If part of the program is wrong, just go into edit mode and change a few numbers/codes.
Instead of taking a drill press and drilling out holes in your part, a CNC program can be written to save save if you have many holes or parts, especially if they are close tolerance. Just punch in the drilling cycle code, the coordinates of the holes, and you have yourself a simple drilling program. Of course there’s more to it than that, such as machine and tool set-up, but if you have hundreds or thousands of holes to drill, you’re going to want a CNC machine.
