The document is a final year project presentation for a water jet cutting machine developed by three students - Ammar Ahmed Abdellah, Mohamed Ibrahim El-abd, and TarekAbd El-latifFouad - at the Arab Academy for Science, Technology and Maritime Transport, under the supervision of Dr. Mohamed abd el-mohsen. It begins by acknowledging the support received from their department head, project supervisor, and a teacher's assistant. The introduction provides a high-level overview of what a water jet cutting machine system is, explaining that it uses high pressure water jets, with or without abrasives, to cut a variety of materials like metals, stone, plastics

I-Introduction
What is a Waterjet Cutting Machine System?
Water jet machining and abrasive water jet cutting machine are non-traditional or non-convential
processes .In these processes the mechanical energy of water and abrasive phases are used to achieve
material removal or machining. Abrasive jet and water only jet cutter use the technology of high
pressure water typically between 30,000 and 60,000 psi, to create extremely concentrated force to
cut stuff. A water cutter pressurizes a stream of pure water flow (without abrasive) to cut materials
such as foam, rubber, plastic, cloth, carpet and wood. Abrasive jet cutters mix abrasive garnet to a
pressurized water stream to cut harder materials. Examples are: stainless steel, titanium, glass,

3. ceramic tile, marble and granite. Water jet metal cutting machine yields very little heat therefore no
heat affected zone (HAZ), and hence in most cases will not require further heat treatment. Water jet
machining is also considered as a "cold cut" process and therefore is safe for cutting flammable
materials such as plastic and polymers. With a reasonable cutting speed setting, the edges resulted
are often of satisfactory. Precision water jet cutter is very handy and versatile cutting equipment with
affordable price for stone cutting and metal working in job shops.
