HI ART,
 I may have stumbled onto another temp. rule.
If the profile BEGINS with an arc, it needs to be tangential to the end axis...(hope I said that right)

If it's over the origin like the pic., it cuts the tops off of the humps of the profile.

May need to automatically plop a tangent line in .....from the origin up to the profile or something.
Or just be aware of it and draw the profile correctly.  ::)

RC
I am hopeful that I made some progress on finding my errors,and have re D/L'd stdcad,and seems to have solved most issues,still an intersecting thing going on and off,but most work well. I'll let you look at the attached and see for yourself. LOOKS GOOD1 I'm not right now worried about the tool,or path. One set at a time.  .DXF is there too.  Thanks,   Hank S.

I agree Hank, that does look much better.
We're on a roll now,

I need to clarify my last post.
Three dxf's attached.
One is "Tan +" and works perfectly.
Two is "Tan-" and gives a Neg.Y error. (as it should)
Three is "Tan-Shifted"  Shifted to the left to be completely Y Pos.

#3 DOESN'T follows the temp rule mentioned earlier about being "out of tangent" with the origin.

Just be careful beginning the profile with an arc.

I just confused myself.  ::)  :D

OK ART, I think I can verify this, hope others can too.
I took the BPIN.DXF from reply #697 which cut the humps off, ( attach #1 below), Trimmed it to the origin, (pics), and it does fine.
Thanks,
RC

Dave,
  If you don't mind, here is just ONE more ...then I gotta go.
3 simple 3pt arcs. Works perfectly in "other" CAM.  ::)
Works well also if drawn the same way with "other" CAD.  ::)

Please post your results,
Thanks.

Yes, same as you, RC, see screenshot below:

Quick read of post and thus reactive comment.
Doing something like your showing could be considered a facing operation  .
And facing isn't implemeted yet, remember the man face dxf posted and Art's comment.

Hi, RC & Art, All

That dose seem to fix the drawing for the most part.

But it brings to Light a possible Issue with the Left hand side of the rough profile not respecting the Tool width values and leaving the rough cut short on the left.

Hear are 2 Pic's, What do you think. ?

Thanks, Chip

Hi Guys:


  My personal though is that I may have to respecify tools.. A center tool will be considered to cut on both sides of the tool, a right only on the right side, and a left tool only on its left side.

Soemhow I have to deal with the problems of gouging a tool on its non-cutting side.. does the above sound like a proper solution. This means left pointing tools woudl only cut right to left,
right tools woudl cut only left to right, and center tools woudl default to right to left, but will be considered as cutting on either side of the tip..

Art

( Just thinking..)

Art,
You mentioned about creating other topics.
Maybe the time to do that will be after some release date or
manual revision.
I hope to have revision 2 to the manual posted today and that should capture
replies up to DEC 17 and it will be in  some sort of common breakdown relative to
the program. Then the next update may include to current replies.
Back to cut and paste,
RICH
