Maybe this will still work. A or B is just a designation, right?

It will be a trunnion table, I guess call that "A" that the "B" rotary will sit on.

I want to probe a shaft to make "A" rotate to vertical. Even though the shaft  is fixtured to"B", "B" is just sitting there.

So let's say everytime I want to do this procedure, I can just load up your screenset? For my 5 axis use (no probing just cutting) I would load that screenset?

I don't have my machine running yet, but very close... I'm not familiar with changing screens and how does it affect the settings... i.e. ball screw pitch, acceleration settings, preferences. Does that make sense?

With that machstdmill do you offer a 5 axis screen?

It's not so much the physical profile that i'm interested in.

Its the inches per degree that gives you the acceleration, and the finer measurement of jerk.

These are very important in making a cam that is as fast as possible... But also easy on valvetrain.

.001" isn't tight enough linear resolution.1 degree may be fine, .5 would be good i think.

Thanks, I knew about the probe... but just not accurate enough for my work. Thank you very much for explanation on how you do it!

There's those fancy 2 chanel data aquisition boxes (have to look up names again) that can be had for under $100 with software. I guess that will be my best option... unless there are other options?

I'm thinking of building a camshaft measuring test stand, needs to be accurate to .00005" or at worst case .0005".

My original plan was to use a linear digital indicator with a SPC cable going into excel for graphing. But... I do need a rotation means of measurement also for my formula's.

I don't know how to let the rotation record simultaneously... or in sync with the linear.

Any thoughts?

What are you using for your probing routines if not the wizard?

what does MSM stand for?

And to hi-jack this thread... can the Mach probing wizard find the center of an outside dia of a shaft... or center of a hole only?

BR549, show some pics of how you make your cams in the 4thaxis.

Great work and thread Steve!
