Note:The values are not for rocker arms (one of the next steps) but just for … um … howsitcalled? We call them cup-pushers. The lobe more or less hammers directly onto the valve stem.
Do you include a clearance ramp in your cam profile?
I dont recall though, is there any looping or math iteration/convergence type issues in developing the profile? Just wondering why plain old Excel would not satisfy the task assuming its crunching equations kind of linearly?
For me, Excel is no software to use. Users would have to buy Excel and I certainly am not among their clients.
For now, I'll call mine KamKalk, so it sounds kraut-isch. But I hope to find a better name. Nick

I'm talking about the situation where a flat bottomed tappet edge can 'dig' on a (non harmonic / flat sided) cam profile
Have you given thought to calculating the minimum diameter lifter so this cannot happen?
You get that, when tip-radius + lift >= base circle radius.
I would like to see a speed profile looking like a full 360 degree sine,
But for that to work, you'll have to include the weight of the valve + spring + cap etc.
That then brings the last possible and very interesting calculation max flow through valve.
After the program is complete ...
I'll have two beer now!Nick

Next, milling with the cutter over the top of the arc (that is easy, I think as for now) ...
My only concern with the continuous motion is that the user would have to be certain they have a center cutting endmill,
But as it looks, I have to go over the math again. Maybe that will take until the weekend (to find my dumb error).
