What is CNC Machine?
Computer Numerical Control (CNC) is a process by which a machine is programmed to operate and produce a hardware design. In other words, it is a principle by which computers control machines to operate.
CNC is used in milling, lathe, laser cutting, plasma cutting, router and 3D printing, turning, grinding, drilling, threading, tapping, punching and nibbling.
What is CNC Programming?
Writing a code for the machine to perform required operation is CNC programming.
What is CNC Operation?
Operating the programmed machine by using the hardware device is CNC operation.
Advantages of CNC designing over manual designing:
- Saves time
- Reduces labour
- Replicates exact design in mass production
