High Pressure Waterjet
Application Note High Pressure Waterjet A water jet is a cutting tool capable of slicing metal or other materials by using a narrow stream of water at high velocity and pressure, or a mixture of water and an abrasive substance. The process erodes the materials in the same way as water erosion found in nature but accelerated and concentrated through high pressure. It is often used in the fabrication or manufacture of parts for machinery and other industries. It is used in applications in the mining to aerospace industries where it performs operations such as cutting, shaping, carving, and reaming. The water jet is usually connected to a high-pressure water pump (Viatran supplies units at 60K PSI) where the water is then ejected from the nozzle, cutting through the material by spraying it with the jet of high-speed water. Adding suspended grit or other abrasives, such as garnet and aluminum oxide, can accelerate this process. Because the characteristics of the cutting stream can be easily modified, water jets can be used to cut materials from processed food to exotic metals. There are few materials that cannot be effectively cut with a water jet cutter. Two of these are tempered glass and certain ceramics are resistant to water jet cutting. Water jet cuts are not typically limited by the thickness of the material, and are capable of cutting materials over a foot (30 cm) thick. An important benefit of the water jet cutter is the ability to cut material without compromising the material's inherent structure. The effects of heat are minimized by the water jet. -

Water Jet Cutter: an Efficient Tool for Composite Product Development
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by National Aerospace Laboratories Institutional Repository National Conference on Scientific Achievements of SC & ST Scientists & Technologists 14–16 April 2009, National Aerospace Laboratories, Bangalore-17 Water Jet Cutter: An Efficient Tool for Composite Product Development D. Babu Rao*, D. Baskey and R.S. Rawat Advanced Composites Division, National Aerospace Laboratories, Council of Scientific and Industrial Research, Bangalore-560017, INDIA E-mail: *[email protected] ABSTRACT Water jet cutter is a powerful tool in the present engineering scenario which works on the principle of micro erosion occurring when large volume of water is forced through a nozzle of reduced cross section at high velocity (~Mach No: 3) and elevated pressure (~3000 bar). Water jet cutter was used to cut lumber by forestry engineer Dr. Norman Franz in 1950s.[1] Water jet cutting find applications in diverse industries from mining to aerospace, where it is used for cutting, shaping, carving and reaming. Water jet cutting has many advantages like no local heat generation, smaller kerf width hence less material wastage, faster and cheaper, higher accuracy, automation capability, and less burr and rough edge etc. Advanced Composites Division (ACD) is actively engaged in the development of various aircraft parts for on-going National Programmes like TEJAS, SARAS etc. For the development of composite parts the most important aspect is tooling. To develop a tool, one has to start with master model. The technology used in ACD for composite tooling is based on splash technique. To fabricate master models and moulds, we require templates such as base plates, master model check templates, mould-ribs, reference pad fixing location templates and mould check templates etc. -

We resolve the moment of impact bonding through real-time observations of single particle impacts with micron-scale and nanosecond-level resolution. We offer the first in-situ observation of a material- dependent threshold velocity, above which the particle undergoes an impact-induced jet-like material ejection and adheres to the substrate. -

The liquid precursor can be cured by heating 130 – 170 ⁰C to form ester crosslinks which convert the liquid into a hard plastic that can be used for a variety of commodity and disposable applications. Over the course of 2-3 months of water exposure these links break down eliminating the environmental impact of Nuplon. Goal Evaluate ability for Nupon to be machined/cut to form a variety of consumer products including toys as well as evaluate other mechanical properties. Water-Jet Cutting When put into a high-pressure water-jet cutter, the Nuplon M317 sliced cleanly (cutting done by McKinney Corp.). Setup for cutting Water-jet cutting Figure 1. High-Pressure water-jet cutting image series. Impact Disposition To test the impact disposition of the Nuplon sheet, a piece of 8 x 5 x ¾ inch thick Nuplon sheet (type M317) was made and then shot with a 0.22 caliber firearm. The piece shattered into large chunks on impact indicating that in conditions of rapid/hard impact the failure mode for Nuplon is fracture. 0.22 mm round in clip. ¾ inch sheet of Nuplon type M317 Impact shatter Figure 2. High-Impact testing image series. Similarly tests with punch-cutting Nuplon indicated that the material shatters with hard impact. In the future, a more flexible design of the polymer may enable shear-cutting but for the current Nuplon type M317 impact cutting/machining is not suggested and processing should be performed by abrasion-type cutting (sawing, drilling, etc.).
