Calculation of Exit Jet Energy in Abrasive Water Jet Cutting

Manufacturing Science and Engineering: Volume 1 — New Product Introduction; Measurement and Inspection of Products and Processes; Non-Traditional Manufacturing Processes of the 1990s, 1994
Abstract In the paper, a model for the calculation of the energy of an exiting abrasive water jet after material cutting is developed based on an energetical balance inside the workpiece. An energy absorption parameter χ(h) is defined which is based on a parabolic striation model.

Modeling of Abrasive Water-Jet Cutting Processes

1998
Over the years, several models are developed to describe the abrasive water-jet cutting process. Generally, these models are attempts to estimate the depth of cut achievable in different materials cut by abrasive water jets under certain process conditions. The reader will find other models, such as for material-removal processes and for abrasive water

Pulsating Abrasive Water Jet Cutting Using a Standard Abrasive Injection Cutting Head – Preliminary Tests

2020
The paper focuses on research into disintegration effects of a pulsating abrasive water jet using a standard abrasive injection cutting head. Forced pulses of a frequency of 20 kHz were generated by a piezoelectric pulse generator using a sonotrode placed in a high pressure system in front of a water jet nozzle.

Automated abrasive water jet pin cutting system

2010 1st International Conference on Applied Robotics for the Power Industry, 2010
After a long operation time, steam turbine blades need to be removed, inspected and/or replaced. Numerous steam turbine fleets feature blades that are attached to the rotor discs by the means of pins. To change these blades, the pins have to be removed. At the time being, the pins are removed using a hydraulic jack. Roughly ten percent of the pins of a

An exploration of an abrasive water jet cutting front profile

The International Journal of Advanced Manufacturing Technology, 2015
Abrasive water jet (AWJ) now is used as a precision cutting tool. With this tool, dimension tolerance less than 0.1 mm is expected in the cutting process. This dimension tolerance is enough for some applications. However, higher precision is necessary in order to use AWJ in some other applications.

Recycling of abrasives in abrasive water jet cutting with different types of granite

Arabian Journal of Geosciences, 2013
The cost of abrasives has restricted usage of abrasive water jet (AWJ) technology in natural stone cutting applications. However, recycling of the abrasives makes the technology more economical, effective, and environmentally friendly. In this study, significant rock properties affecting the recycling of abrasives in AWJ cutting of granites are ...

New Approach of Recycling of Abrasives for Water Jet Cutting

2018
The recycling or reuse of material in production becomes as a saving task for sustainable and environmental competitive production. Sustainability means not only achieving cost efficient process but also eco efficient. The design of the abrasive recycling system is desirable because of the growing growth and development of the abrasive water jet ...
