Good to see some liteply being cut - very satisfying to plug bits together using the tabs etc. and have it build almost in your hands.  I know what you mean about mixing the inside profile and outside profile in CAM toolpaths.  So easy to do and very annoying!
It's been a while since I cut that material (more aluminium recently, plus some MDF and thick plywood) but my cutting speeds were much faster than that and quality was OK.  Worth experimenting a bit more?  I don't have much time in the workshop so time is precious.
What cutter is that?  I use a 2 'blade' TCT 3mm super cheap e-bay bit and it works fine.
Thanks
