Roy (Shred) asked me about the mathematics of making a tapered flute with a ball mill by tilting the workpiece along the path of the ball mill. For an example of what we're talking about, look at this old thread
http://www.homemodelenginemachinist.com/index.php?topic=612.msg4066#msg4066
where Bogs used the technique to flute the tapered connecting rod of an engine.
I've derived a mathematical relation for the required tilt of the workpiece as a function of:
the radii at the two ends of the flute
the length of the flute
the diameter of the ball mill
The derivation is very straightforward and the calculation can be done easily on any scientific calculator (the quintessential shop tool) but, if enough people are stupefied by the math, I'll consider putting it together as a program and put it on my page.
