Waterjet cutting of superalloys for aerospace applications

The waterjet cutting system implements Dynamic Waterjet Technology. It has active tolerance control to offer unprecedented speed, accuracy and versatility. The patent system develops components with tight tolerances even at the large paces that practically discards taper by using angular compensation. It utilizes an advanced sophisticated motion system that comprises of new mathematical cutting models to monitor the small articulated wrist associated with the cutting head.

It is possible to title the cutting head in any direction by using the wrist to compensate the stream lag and taper occurring with the traditional waterjet cutting systems. For the traditional waterjets, it is essential to decelerate the process to reduce or discard the finished component tolerance errors because of the stream lag and taper. By using waterjet, it is possible to overcome these drawbacks. The position of cutting head can be dynamically controlled by using software that can level the tilt ant rotation required at the various incremental points with a cutting path.

An appropriate cutting speed can be maintained with this software to keep the components taper- free and within tolerance. It is essential to increase the tilt while increasing the cutting pace and in many cases, fast cutting speed can be obtained with the potential to tilt the cutting head. Therefore, Waterjet can develop excellent components at the larger speeds as compared to the traditional waterjet cutting equipments.

Wateret cutting machine capability
a.       Accuracy of +/- 0.0015 inch per 3 feet and speed limit about 0 to 500 ipm
b.      Cutting area about 2m x 2m cutting bed with lengthy pieces having indexing potential
c.       Several tolerance levels and fine cut
d.      Mix and match edge styles on the same part depending on their use
e.      Nominal machining is required on components because of tighter tolerances and outstanding edge quality and highly available due to no need to handle the scrap
f.        Nesting, flattening, kitting, toll cutting and JIT service
g.       Small edge stress and no heat affected region so fit for the elevated temperature and corrosion resistance applications.

Benefits
a.       Cut components 25 to 400% more quickly as compared to the traditional flat stock waterjet cutting devices
b.      Cut various materials such as glass, metal and composites
c.       No additional finishing is needed
d.      Improve cut part tolerances and shape at the significantly high speeds
e.      Virtually prevent aper
f.        Decreases component cost
g.       Cut components by using CAD file and draw directly into FlowMaster

Applications
1.       Aerospace- Titanium bodies and engine materials constructed from titanium, aluminium and heat resistant alloys such as Monel 400 and others.
2.       Automotive- Truck bed liners, interior trim, firewall
3.       Gasket for aircraft, automobile, marine, copper and rubber
4.       Stainless glass, Outdoor stone and flooring, wall inlay, flat glass
5.       Acrylics , plastics, ceramics, stainless steel, Inconel, mild steel, titanium, brass

The waterjet cutting technology has made it easier to cut the corrosion resistant alloys that are usually a hard material that need expensive cutting processes.
