Process
There are six main process characteristics to water jet cutting:
- Uses a high velocity stream of abrasive particles suspended in a stream of Ultra High Pressure Water (30,000–90,000 psi) which is produced by a water jet intensifier pump.
- Is used for machining a large array of materials, including heat-sensitive, delicate or very hard materials.
- Produces no heat damage to workpiece surface or edges.
- Nozzles are typically made of sintered boride.
- Produces a taper of less than 1 degree on most cuts, which can be reduced or eliminated entirely by slowing down the cut process.
- Distance of nozzle from workpiece affects the size of the kerf and the removal rate of material. Typical distance is .125″ (3.175 mm).
Temperature is not as much of a factor.

“The process of discovery is very simple. An unwearied and systematic application of known laws to nature causes the unknown to reveal themselves.”
—Henry David Thoreau (1817–1862)
“Opinions are formed in a process of open discussion and public debate, and where no opportunity for the forming of opinions exists, there may be moods—moods of the masses and moods of individuals, the latter no less fickle and unreliable than the former—but no opinion.”
