I believe you could also use this to compute flutes for a tapered column as well. Solve for the angle as if parallel and add the taper angle.

John i am with you on that, how can you add or subtract or multiply etc letters of the alphabet ????

Those values give me the correct 0 deg answer. Thanks Marv!kvom said:I tried the program, but something seems odd. By specifying the same start/end radii I expected that the angle would be 0. However, I got this:
Ball mill diameter [0.5 in] ? 1
Flute radius at small end [0.1 in] ? .25
Flute radius at large end [0.2 in] ? .25
Length of flute [3 in] ?
Depth of cut at small end of flute = 0.0670 in
Depth of cut at large end of flute = 0.4330 in
Required workpiece inclination angle = 6.9562 deg = 6 deg, 57 min, 22 sec
In the initial derivation, H = Zf-Zs but expanded to = Zs-Zf. I highlighted Zf in the attached image for lack of better tools here. I think all that would do is change the direction of the slope, so it's then only a pedantic issue.mklotz said:The equation for 'h' is h = zf - zs in both the derivation and in the program. I guess I don't understand your comment.
Actually I do... I wrote end-user-software for a major computer company for several years... 99% of the work is stupid-user input validation which I wish on nobody.You're right about the units. They don't matter so the user can use any consistent set of units. However, you have to have my appreciation for just how dense some of my 'clients' are. .... If that makes me an unsympathetic hard ass, so be it.
