How to Use a Computer Numerical Control (CNC) Machine

CNC means computer numerical control and this article gives a brief overview on the operation of a CNC machine connected to a PC running EMCO. Other operating systems and software are also available but that is beyond the scope of this article. CNC machines are normally found in machine shops, but with recent development of inexpensive controllers are now showing up more commonly in home shops. CNC machines are part of the machining process when high quantity is needed.

Tips

  • Model G01 Linear interpolation in working feed
  • Model G03 Circular interpolation, counter-clockwise
  • Appendix: Model G00 Rapid motion
  • Model G02 Circular interpolation, clockwise

Warnings

  • Never manually remove a tool from the tool holder carousel or the spindle
  • At anytime the machine can be stopped by pressing the red kill-button on the front top right of the machine
