Waterjet uses up to 60,000 psi pressure to project water streams through the cutting head. With the high pressure of the water, and abrasive particles (garnet) mixed in with the cutting stream, the waterjet is able to cut up to 12" thick materials.
the first jet engine was invented by a engish engineer called sir Frank Whittle but it was later invented in Germany by a Dr. Hans von Ohain, but Frank had already patented the jet engine.
The Germans invented the first operational jet engine during WW2.
well he invented the jet engine because he thought it a good idea.sorry not much help.
we use water for maching in WJM, and abrasives in AJM.
In 1967 the Laser Machines for cutting metal was invented by the British. They discovered the laser assisted oxygen jet cutting laser machine for cutting metals.
Industries that requires the fabrication of machine pieces or the cutting and shaping of a material, such as aerospace and mining, use water jet cutting.

Their are many advantages to water jet cutting that make it one of the best methods to cut items. First off since it requires and produces no heat the materials are not warped due to the high temperatures. Also water jet cutting allows for extreme precision that is not available from other forms of cutting.

Abrasive water jet cutting can cut aluminium, stainless steel and brass with no ternishing. It can also cut ceramic floor and wall tiles, granite, marble, slate and limestone.
A water-jet loom is a machine for weaving cloth (loom) which uses a jet of water to insert the weft (crosswise threads) into the warp (lengthwise threads).
Abrasive water-jet cutting, is when one uses water jets for cutting and removing materials. The water jets may contain abrasive powder, and can be used to cut titanium, marble, and glass.
It depends on the material type and thickness that you are cutting.
Dr. John H. Olsen
Someone accidentally strapped a fully functional jet engine to a pair of water skis.
Water jet machines are not a health device but rather cutter tools for cutting different types of materials with very high pressure of water or a mixtures of water and a substance of sorts.
