What is a Waterjet Cutting Model? GermanGulf.com

The abrasive waterjet cutting model is, perhaps, the most significant factor in propelling abrasive waterjets into mainstream manufacturing. Advancements in the OMAX cutting model have decreased part production times, increased cutting precision, and made OMAX abrasive waterjets very easy to program.

The cutting model uses sophisticated mathematical modeling to predict the precise motion and shape of the jet stream along each entity of a tool path based on the operating parameters. The cutting tool on an abrasive waterjet is a high-velocity stream of water and abrasive, known as the jet stream. 

The cutting model uses sophisticated mathematical modeling to predict the precise motion and shape of the jet stream along each entity of a tool path based on the operating parameters. The cutting tool on an abrasive waterjet is a high-velocity stream of water and abrasive, known as the jet stream. Unlike rigid cutting tools, such as a tool on a CNC mill, the jet stream is a "floppy" tool that bends as it cuts, and the shape of the stream changes depending on how fast it’s moved. This means that a waterjet will tend to undercut corners and swing wide on curves if it’s moved like a traditional, rigid cutting tool.  The jet stream will react differently when cutting different material types, different thicknesses and at different speeds. In order to produce precision parts in a cost-efficient manner, motion control system must compensate for the behavior of the jet stream.

Early versions of waterjets required a lot of trial and error and a skilled programmer to adjust the jet motion to produce accurate parts. Now, advanced waterjets use cutting models that automatically predict the behavior of the jet stream and make adjustments to compensate for that behavior. 

With OMAX waterjets, a machine operator simply enters the material type, thickness and desired edge quality, and for the given part file, the OMAX machine controller automatically determines and sets the optimal speed and path the cutting head will move along to cut a high tolerance part in the least amount of time. The OMAX 4th generation cutting model is the most advanced abrasive waterjet cutting model in the world, in most cases cutting on the OMAX will result in more accurate parts in less time than when cutting on other waterjets.

Abrasive Waterjet Increases CNC Milling Profitability - German-Gulf Enterprises Ltd

An ever growing number of fabricators and machine shops are gaining a competitive advantage by incorporating abrasive waterjets to their machining mix. In fact, abrasive waterjet machining is one of the fastest growing machining technologies in manufacturing. Smart businesses continuously look for purchases that will increase their productivity and reduce production costs. An abrasive waterjet can do exactly that by streamlining workflows and wasting less material.

Near Net Shaping with the Waterjet Saves Time, Tooling, and Material Expenses

Many manufacturers now cut the majority of a part on an abrasive waterjet and then move the part to a mill for finishing operations. Integrating this near net shape cutting into the process significantly reduces production time. An abrasive waterjet can handle large sheets of raw material and cut multiple blanks with very little setup and fixturing time. OMAX Waterjets are so easy to use that one operator can often run multiple machines simultaneously. The waterjets are set up in a U-shape and one operator runs all three.

Better Material Use Reduces Production Costs

Waterjet machining is a cold process that doesn’t warp, harden or stress the material during cutting. The cut edge quality is very good and typically doesn’t require secondary operations to smooth the edge finish. Since there’s no heat-affected zone and a small kerf, waterjet cut parts can be tightly nested on a work piece. With thermal cutting processes such as plasma and laser, the cut edges are melted, which means more space is required between nested parts, so more raw material is needed per part.

More Capabilities Means More Business

With a multi-axis A-Jet cutting head, an OMAX waterjet can easily cut beveled edges, angled sides and countersinks in materials that are difficult to machine on traditional CNC equipment. Some shops now use their waterjets to cut components to repair or enhance other machines on the manufacturing floor. The OMAX CAD/CAM software has tools to automatically generate part drawings for gears, sprockets, cams and other components that can be customized and cut from almost any material.
