With a Waterjet system, you will experience virtually no taper. In the case of conventional waterjet cutting, the taper you get is a function of the cut speed. However, the worst taper you will get will be equal to the maximum kerf width at the top (example: 0.035″) and 0.000″. at the bottom. As you slow down the taper will be reduced until you get parallel sides. Most tapers you see on precise cuts are 0.002″ to 0.004″ on a side.
