3D Wrapping

[khalid]

Thanks for the information John

I forgot the speeds. I had the x axis set at .6ips, z at .2ips, indexer set to 960 steps per linear inch (prt control box, half stepping, 400 steps per rev, 18:1 gearbox, 7.5In in circumferance.) I have a very old pr32 (32x32x7 with ballscrew axes) and prt control with the older control cards.

My results on wrapping were disappointing so I want to go over them and see if you can tell me what went wrong.

I used Millwizard and took a stl in and it was 12" in X and 4" in Y.

and created a roughing toolpath and finishing toolpath.
Then i took the converter Jim Anders posted link:
http://www.spauldingbryant.com/sbconvert/
and ran both toolpaths thru it.

I then turned down a square to give it a 4" CIRCUMFERENCE (equal to the Y measurement of 4" of the stl).

Then i Zzero'ed the .25 endmill for the roughing pass to the center of the stock and this is the result:

I would gladly send all toolpaths to anyone who could read them and maybe figure out what went wrong?

I would have set up the model so that the xy zero was at the bottom left of the flat model and the z zero was the "table" or bottom of the model. Then I would have imported the stl into aspire. I would have added planar shape underneath it to lift the whole thing up so that the model was only a little bit under the top of the model thickness. In my case, I used .05in. I then figured out how to set the unit values so that one rotation of the indexer worked out to be one circumferance. I then told aspire to machine a toolpath along the x axis (y was the indexer motor). Worked like a charm and no converter as I disconnected the y motor and replaced it with the indexer.

I think that software is set up such that you provide a "flat" relief and it converts to either xzA or yzA format depending on how your
indexer rolls. I swapped my y axis driver to the stepper driver for mine, so as long as I lay out my files with circumerance in mind, I don't
need to convert. This is bad because deskproto trial wants to talk in xza format and I'm not sure how to configure my old prt box to do that.
I do have a spare driver channel.

Kalid say ... "RON..The Eagle on the indexer is not made or cut by me..I think it was done by VELLECA5555 on Artcam Forum.. "

Thanks Kalid ...

That photo is of my work ... is a VELLECA work ...
The photo was in ArtCAM forum in to a topic of Kalid, but isn't a Kalid work is my, Velleca ...

Made with the unwrapping function of the ArtCAM Pro "8" ...

MADE AND CUT BY VELLECA not Kalid ...

Is a simple unwrap of a planar figure I did made with a photo only and Shape editor ... and first that I did saw the GIGGALO's video on that topic ...

The topic is that one ... http://forum.artcam.com/viewtopic.ph...55&start=0

And here on the old and new version after a accidental cut ...
http://www.velleca.it/manualiforum/T...cancelated.rar

And in it you can find two videos made by GIGGALO ... Thanks Giggalo ...

I did made other tests with that function ...
