One Dimensional Cutting
Slitting with a continuous waterjet stream is often used in one dimensional water jet cutting systems. The frame of the system is usually quite simple; waterjet cutting speeds are high and the system is almost always pure water cutting only (no abrasives) using KMT Aqualine Pneumatic Valves Cutting Nozzles. The most important considerations are speed of waterjet cutting, reliability and minimal moisture residue (which is very low due to the high speeds and small waterjet stream).
Two Dimensional Cutting
The most popular application is the 2D waterjet X-Y cutting process. The KMT Waterjet cutting head, using the KMT Autoline II or KMT IDE cutting head moves in X-Y axes, according to the outputs given by the CNC Motion Controller. In many cases, the Z (height) axis is controllable in order to adapt to non-flat or thicker materials; in such cases, the waterjet cutting head needs to be very close to the material being cut. This type of waterjet system is best for rapid production of many different types of parts from different materials.
Three Dimensional Cutting
Three dimensional systems are designed for demanding applications. By using a cutting head with five axes, cones can be cut from flat sheets, holes can be drilled into tubes and ribbed/beveled edges can be produced. While such flexible systems come at a price, they can be used in the most advanced cutting applications and normally pay for themselves as they are extremely versatile:
• Abrasive Cutting
Engine components made in titanium, aluminum and stainless steel; turbine blades, marble and other decorative stone.
• Pure Water Cutting
Components for car interiors such as carpets, door panels, bumpers, dashboards, instrument panels, glove compartments, etc.
In most robotic waterjet cutting systems, the cutting head is attached to a robot arm. For three dimensional waterjet cutting, industrial robots and motion control technology are used, thus providing unrivalled flexibility, which is crucial considering the constant changes made to production processes.
It is, for example, very easy to modify the cutting program so that several tasks are carried out simultaneously. There is no need for a system reset or similar operation. Robotic waterjet cutting is very safe, cost-effective, productive and protect the environment because they provide a viable alternative to conventional machining methods such as sawing, thermal cutting (plasma/laser), punching, milling and other mechanical processes (deburring of cast and forged parts or composites).
