forcing abrasives over work piece at higher speed for cutting . it is unconventional machining process .
In ordinary machining we use harder tool to work on workpiece , this limitation is overcome by unconventional machining. unconventional machining is directly using some sort of indirect energy for machining. Example : sparks, lasers, heat , chemicals etc.. applied in EDM ,laser cutting machines...etc
It is the height, width and length of a jet engine.
Jet Ratio: it is defined as the ratio of the pitch diameter (D) of the pelton turbine to the diameter of the jet (d). It is denoted by m and is given asm = D/d (=12 for most cases)
Water jet

we use water for maching in WJM, and abrasives in AJM.
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.

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.
A forced draught is where the air flow comes directly from the fan to the object. Such as an hair dryer.An induced draught is where the air flow is induced {lit lead in} by a separate flow of air. For example, an abrasive jet would quickly wear out if the abrasive passed through the jet nozzle. the flow of abrasive is added (induced) into the air flow by a jet of clean air.If an air flow is corrosive or very dirty then an induced flow system would be appropriate.
An abrasive jet can cut half-inch thick titanium at the rate of 7 inches per minute.
Three common methods of making gaskets are: Die-Cutting: This involves using a die to cut gaskets from sheets of material, allowing for precise shapes and sizes tailored to specific applications. CNC Machining: Computer Numerical Control (CNC) machines can precisely cut gaskets from various materials, providing high accuracy and the ability to produce complex designs. Water Jet Cutting: This method uses a high-pressure stream of water mixed with abrasive materials to cut gaskets from a wide range of materials, ensuring clean edges and minimal material waste.
it depends on what kind of jet it is. 737 jet: 200 747 jet: 500 757 jet: 280 767 jet: 290 777 jet: 550 787 jet: 350
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 correct phrase is "at my jet." This expression refers to being in proximity to or present at the location of your jet. "On my jet" would imply being physically on top of or aboard the jet itself.
Sandblasting (aka Gritblasting) is an industrial process by which excess materials, paints, debris, etc can be removed from a surface (typically uneven metallic surfaces). Two basic systems, the suction type and the gravity feed/pressure type system, both utilize air pressure combined with an abrasive compound to accomplish this. The abrasive compound is typically a processed sand with silica content or abrasive material such as aluminum oxide or glass beads. Air pressure forces the abrasive through a hardened nozzle in a jet stream which allows it to remove contaminants from the surface of the target. This process is commonly used in the repair/restoration of industrial mechanical and structural components (ie: bridges, heavy duty machinery) and more common municipal applications like removal of graffiti or before re-painting road traffic lines.
