Waterjet Web Reference Calculator

This software requires Windows 95, 98, 2000 NT 4.0, XP or Vista.
Version 2.4, Updated 5/31/2003


Computes fastest waterjet linear feed rate to cut through a given material, and a slower linear rate for general waterjet machining (using Dr. Jay Zeng’s doctoral thesis for the cutting model). It’s very simple, but it will give the novice a good idea of how fast a waterjet can machine.

Note that this calculator gives linear feed rates–for cutting in a straight line–which can be misleading.When making real parts, the waterjet needs to slow down for corners and intricate geometry. This calculator will let you compare cutting rates of different materials, and different nozzle setups, but it can’t be used to estimate how long it will take to make a part. Making a real part will always be slower than the time given by the calculator.
