Thanks for the reply.
My google skills were weak. I never found anything on this or any other 3D printing forum (I did search for a few days before asking) but there is a lot written about CNC machines for "tool path generation algorithms". I think that will get me in the right direction. "Slicer" is apparently a bad search term when you want to dive into the technical details.
I do appreciate your time though!

Quotes from my earlier posts:
Also read this and many other topics - Daid has some great explanations too - he wrote Cura although there are more authors now:
