Different CNC Machining Processes

1. CNC Drilling
During CNC drilling, a CNC machine typically advances a rotating drill perpendicular to the workpiece surface. This technique produces vertically aligned holes with a diameter equal to that of the drill bit used. Drilling operations include boring, milling, counterboring, and tapping.

 

2. CNC Milling
During CNC milling, the CNC machine feeds the workpiece into the cutter in the same direction as the cutter's rotation, rather than the opposite direction as in manual milling.

 

Milling operations include:

Face milling: Cuts flat surfaces, shallow surfaces, and cavities in the bottom of the workpiece.

Peripheral milling: Cuts deep cavities within the workpiece, such as grooves and threads.

3. CNC Turning
In CNC turning, the CNC machine moves linearly along the surface of the rotating workpiece, feeding the cutter. This removes material around the circumference until the desired diameter is reached. This technique can create cylindrical parts with external and internal features, such as grooves, tapers, and threads. Turning operations include boring, facing, grooving, and threading.

 

4. Electrical Discharge Machining
Electrical discharge machining (EDM) is a process that uses electric sparks to create a specific shape on a part. During this process, an electric current discharge occurs between two electrodes, allowing for the partial removal of material from the workpiece. When the gap between the electrodes decreases, the electric field strength exceeds that of the dielectric, causing current to flow between the two electrodes. As a result, each electrode removes a portion of material from the workpiece. During the"flushing"process, when the current is stopped, a liquid dielectric is introduced to remove debris from the finished part.
