Water Jet Cutting
It is common practice to shape the world around us. By utilizing manufacturing processes we employ machines and raw materials to form final products and apply them to our surroundings. These applications are anything that changes a once stock or raw material into a usable item intended for a specified purpose. Manufacturing processes for example are things such as heat treating, machining, bending, grinding and cutting of the initial product. One kind of machine that is important to industry is called a waterjet. More specifically, a waterjet cutter is to be focused on in this article. The previously mentioned tool is aided to the cutting processes of manufacturing within special circumstances.
Waterjet is a generic term used to describe equipment that uses a high pressure stream of water for cutting or cleaning purposes. Waterjet is a type of machinery that separates into two categories of pure waterjet and abrasivejet. Pure waterjet and water-only cutting are phrases for specifically distinguishing waterjets that only uses water and no additives. Abrasivejet is a subcategory of waterjet in which abrasive materials are introduced to accelerate the process. However, these liquids do not do all the work on their own.
Waterjets work in quite a simple manner. The basic idea is the liquid of either type is pressurized and pumped through a system. Thereafter, it is forced it through a very small hole otherwise known as a nozzle opening. At this point, if the jet only contains pure water it is obviously considered a pure waterjet cutting device. Mix the water with an abrasive substance and you have a very thin stream, traveling very fast, that will rapidly erode most materials. Otherwise known as an abrasivejet cutt...

Conclusion
As it has been stated waterjets are a versatile and innovative tool. This paper hopefully clarified the ability and general uses of what a waterjet cutter can do. These attributes were explained to the fullest extent that was needed to be provided to understand the uses of this machine. As well as how these attributes affect industries that currently uses the tool and those that could benefit from its use. To review, waterjet cutting is a simple manufacturing process that aid in the creation of many finalized products through the pressurized spray of pure water or a water and abrasive mixture. The wide range of uses is only equal to the number of industries it can be used in. Furthermore, once in those industries the quality of final products are only effected by the operator or customers’ skill and imagination for problem solving.

This new form was called hydraulic die-forming. Hydraulic stems from the Greek word hydro meaning water and aulos meaning tube (McCreight, 2004). In today’s society, hydraulic pressing and stamping of dies are used for everything from making small pots and pans to the more extravagant automobile body models. Another use that has recently developed is the more artistic use of, producing form in silver and gold. In order to achieve this smaller, cheaper scale of die-forming experiment were conducted by Richard Thomas and Ruth Girard, which eventually led to the development of the pourable epoxy steel...
Fabrication at the factory utilizes a mix of robotics and manual labor to produce the body of the V-Rod. Robots that are designed to cut pipe are capable of completing a single operation within 3 seconds. Other fabrication robots utilize 1800 watt lasers that can perform cutting operations at the rate of 100 inches per minute. Where robotics can be used to perform high speed cutting and welding operations, skilled workers are a...
The way 3D printing works is by taking virtual designs from a special computer aided design or modeling software and “splits” them into separate cross-sections for the machine to use as a guide. The printer then lays down successive layers of the liquid or powdered material required (metal, plastic, paper, ceramics etc.) and eventually builds the model through these series of cross sections, creating the object desired. This printing layer by layer slowly develops the object.
Milling offers the advantages of being highly precise and having much smoother surface finish (surface roughness of easily around 1 µm ) compared to powder bed fusion additive manufacturing (layer thickness in the range of 20 µm and above; surface roughness of 15 µm and above ). Flat surfaces and sharp corners can be obtained with CNC milling. Similarly, features such as threads and holes are more accurately created through
Water flossing is relatively new on the home dental cleaning scene. It involves a small machine which plugs into an electrical outlet. After filling the water reservoir tank with water, it pumps liquid through the plastic tube to a handheld curved pick. Hold the pick against each tooth gap, so the pressure of this water flushes out all food particles trapped in each space.
Despite the limitations it may have, 3D printing is a real game changing technology with the potential to revolutionize production process of this century. The goodness is that it uses a variety of materials ranging from metals to plastics and is a faster way of producing efficient products. The materials needed for production are less compared to the traditional manufacturing and its products are lighter, complex and even stronger. These properties of 3D printing make it an ideal technology of the time thus its growth will be seen in different sectors of development from aviation to consumer good.
Many parts, for example, screws, nuts, bolts, and fittings, are produced by automatic turning operations [10]. Some alloying elements sometimes added to impart special characteristics to brass. Lead, which is insoluble in copper alloys, is used to improve machinability of leaded brass. However, Pb and Bi or other elements that are used to improve the machinability often deteriorate the low and high temperature ductility of brass [11]. The content of Pb element is varies between 2.5 and 3.5 %, which make the machining processes at high speed and good surface [12]. The solubility of lead in copper alloys is very low therefore, it is found in microstructure as dispersed globules all over the material. These globules lead act as a lubricant decreasing the friction coefficient between the tool and the material by creating discontinuities of chip fragmentation. Therefore, it makes reducing in cutting force and then, the tool wear rate is minimized [13]. Different alloying elements help to improving the machinability are usually added to brass. The most common element using in this situation is lead, which improving the machinability with regard to excellent chip breakage, low tool wear and high applicable cutting parameters. These aspects can be explained by two basic phenomena; first of all, the solubility of lead in brass is extremely low and lead segregates in the entire microstructure, particularly at the grain boundaries. Hence, shear strength is reduced, resulting in very good chip breakage. Secondly, lead exhibits a low melting temperature and during cutting process, a thin, semi-fluid lead film reduces friction with cutting forces

The idea was to improve 3d printer with special technology, a single printer, with multi material features, can transform from any 1D strand into 3d shape, 2d surface into 3d shape or morph from one 3d shape into another. The shape of 3d technology is basic mode for 4d. Objet Connex multi-material technology is an 3D printing important part of his work – and is being used extensively in this new process. The Connex multi material technology allows the researchers to program different material properties into each of the various particles of the designed geometry and harnesses the different water-absorbing properties of the materials to active the self-assembly process. With water as its activation energy, this technique promises new possibilities for embedding programmability and simple decision making into non-electronic based materials.
Hydropower, the use of water to power machinery or produce electricity, provides the most renewable energy in the United States, and uses alternating current in most modern plants ("Hydropower…”). Hydropower relies on the water cycle and is a clean fuel source; it doesn’t pollute the environment like plants that burn fossil fuels. It is by far the most efficient way to generate electricity, being half the cost of using nuclear power, two-fifths the cost of using fossil fuels, and a quarter the cost of using natural gas ("Wind and Water…”). Also, hydropower is not subject to market fluctuations of embargos, and the average lifespan of a facility is 100 years. Hydropower also has many non-energy benefits such as water supply, flood control, navigation, irrigation, and recreation. However, it does face many environmental challenges such as impacts to aquatic habitats, aesthetic alterations of landscapes, changes to water quality, and interruptions of marine life ("Hydropower…”).
