Comparison of conventional and Abrasive water jet machining


Conventional machining

Contact mechanisms
Detonation of an explosive with in a confined space
damage is normally in the form of a narrow slot of varying depth



Abrasive water jet machining

Camelina sativa is an oilseed crop and it might be used as fuel in aircrafts in the near future. A study conducted at Michigan Technological University claimed that Camelina has shown to be one of the more promising alternatives to petroleum jet fuel. They studied the whole process i.e. from planting to airplaneâ„¢s tailpipe. David Shonnard, Robbins Chair Professor of Chemical Engineering, studied the carbon dioxide emissions of jet fuel made from Camelina oil ....etc

Abrasive Jet Machining
abstract

Abrasive water jet machine tools are suddenly being a hit in the market since they are quick to program and could make money on short runs. They are quick to set up, and offer quick turn-around on the machine. They complement existing tools used for either primary or secondary operations and could make parts quickly out of virtually out of any material. One of the major advantage is that they donot heat the material. All sorts of intricate shapes are easy to make. They turns to be ....etc

Abresive Jet Machine



It is a newly developed technology used in industrial countries. This is adopted for machining operations.


Features

In this machine a high velocity of abrasive stream is used for machining. The abrasive particle have a vibration of about 50 hertz is mixed with high pressure gas or air in the mixing chamber. Then the stream is emerges through a small nozzle mounted on a fixture to the work piece.

Water Jet cutting services make use of a super high pressure stream of water that carries an abrasive grit. This abrasive mixes with the water through a venturi effect in what is commonly called the ?focusing tube? just prior to cutting. This mixture of water and abrasive grit exit the focusing tube at speeds of approximately mach 2.5. Cutting pressures range between 45,000 to 60,000 psi for standard cutting models. For brittle, fragile, or delicate materials, piercing pressures range between 15,000 to 20,000 psi, and resume the higher cutting ....etc
