Unique properties of Dynamic Waterjet
Compensates for taper and trailback
Unlike conventional rigid cutting tools, the waterjet will deflect and change shape as it penetrates
and separates the target material. This lack of rigidity is demonstrated by two jet cutting
phenomena—taper and trailback. The wrist is designed to compensate for these idiosyncrasies
through a combination of electromechanical hardware devices and software techniques.
Taper
This illustration shows how a cut into a piece of material typically results in non-vertical walls. The
non-parallel nature of the cut is called taper, and the magnitude and direction of taper is a function of
process parameters such as material thickness and cutting.
Trailback
This illustration shows how the exit of the jet from the material trails back from the entrance point.
Like taper, the magnitude and appearance of the trailback is affected by the cutting process and
target material parameters.
