CNC broaching uses a specialized toothed cutting tool to remove material from a workpiece. The cutting tool itself is called a broach. There are two variations of broaching- linear and rotary. Broaching is generally used to create keyways and profiles into a workpiece.

CNC waterjet cutting is a type of cutting process that uses the force generated by ultra high water pressure to remove material from a workpiece. Water jets can cut material of any thickness and type. Unlike other cutting processes, water jets are a cold-cutting method that doesn't leave any burn marks.

CNC flame cutting is a type of material cutting process that uses oxy-fuel gas to melt and remove workpiece material. The direction and magnitude of the cutting head can be controlled with a computer numerical control machine. CNC flame cutting is not as preferrable as water jets or laser cutters due to the low quality of results obtainable.

Electrical Discharge Machining (EDM) is a type of metal cutting operation that uses the high temperature generated by high-frequency electrical pulses. The pulses are generated due to a high voltage between electrical electrodes and the workpieces. EDM cutting has high precision. However, it is only limited to metals with a low thickness.
