squiggley Spiral toolpath

this is just a .03 rad around a perfect 1.6" dia circle.

Does a small negative offset or tighten tolerance effect this in any manner?

Share sample file?

tolerance was .0005". File was 100kb.

 

Making it higher just makes the entire path more jagged. 

Its also there if I do it as Concentric circles. This should definitely be a very smooth and simple operation! 

this is .00001". File size is 235kb

"Additional Offset" on the Geometry tab. Barring that, there are some surface triangulation options buried in Compare and Edit, I find those are also helpful

1/2 ing the Triangulation does make it smoother, but in my mind if you select Concentric Circles it should be a FIXED Z height until it steps up.

Surface Triangulation defaults to tolerance * .5.

I prefer tolerance * .05

Yes, calculation is a little bit longer, but result is this (no other changes)

I see that too - but why or how would a person know they have to edit some shadow-setting? 

Ramp is only set to *0.25 and makes a perfect path for this! Unfortunately you guys didnt add the Avoid option to it so it's harder to constrain and it wants to do everything.

I "think" the Avoid option is coming to this strategy at some point in the future, but can't say with 100% certainty.

 

As for the tolerance; "usually", it works fine and there's no need to adjust. There are cases, such as this, that we need to tighten things up a bit, and this is the mechanism they implemented. 

To the unasked question of "why don't they just set this as default", I think the answer is consideration of time. Tightening up that much does have an impact on larger parts.

If spiral is set to 0.5 (but should be 0.05) and ramp is .25 I wonder what all the other ones are set as, and how many issues are caused by them? About the only thing I prefer in MasterCam is the ability to do a simple 2D Sweep for things like this. Select my part OD, select the rad contour and you're done.

Oh, they're all set to .5 tolerance as far as I'm aware. I've gone thru my toolpaths and set default on all of them to .05. But, I also do rather small parts with limited surfacing needs, so I seldom notice a hit in performance.

I just changed a Scallop from 0.5 to 0.25 and it made the operation size 20% SMALLER while looking identical. 

*0.05 makes it 30% smaller! Is there really a difference in computation time on this? It's still all too fast for me to even start counting. 

Certainly, Adaptive toolpaths take more time then any surfacing ones I've seen.
