TECHNICAL NOTES 3 Hydraulic Classifiers - Mineral Tech

3.3. This is called the partition curve (sometimes called the Tromp curve) and it shows the fraction of particles at a particular size that will be partitioned to the coarser fraction. The S shaped curve is typical of all practical classifiers and a variety of quantitative expressions have been used to describe the shape of the curve.

On a Tromp curve, you can observe the so-called "bypass level". The bypass level indicates how much % of fine particles go to the coarse stream. This measures, of course, and un-wanted behaviour or an "un-efficiency".

Coding Curves along the Z-Axis on a CNC - WOODWEB

However, assuming this works, it would only work with an arc going straight along either X or Y. While traveling in X or Y the Z-axis could be following a vertical arc. Since the I/J coordinates only apply to 2 axis at a time, though, you couldn't run an arc in Z while traveling at a diagonal across the table. Does this make sense to anyone else?
