Using a Lollipop To Engrave Sidewalls
« on: October 06, 2021, 18:56:06 pm »
I'm still playing with the idea in my wetware system, but the title pretty much describes the idea. 

My thought for CamBam is to rotate the surface and pattern 90 degrees, project lines to surface, rotate back 90 degrees, and then offset hte lines by lollipop ball radius minus cut depth.  It would work ok for linear sidewalls, but for organic shaped sidewalls I am still thinking about some of the limits.  Obviously depth of the cavity needs to be accounted for.  This is purely for cosmetic/marketability.  It should have little to no affect on function. 

I think I can even fake out Camotics to show the cuts due to one of its features/limitations due to flute length.  I need to try it of course.

I made this post because I have not tried it, and I am welcome to a critique of failings in the two ideas and to a superior approach if you know of one. 

I also wondered if modeling the engravings into the 3D model and using a plane slice finish pass with a lollipop might give a desired result. 

I hope to achieve this on a basic 3 axis machine.

Why a lollipop, instead of a regular ball-end mill?  Do your sidewalls have 'undercuts'?

Because its a pattern.  Not vertical lines.  The lollipop creates a small undercut where as a ball nose will just remove any material above the cut.

Its for a flexible media so key locking is not an issue.
