Hum...
With a 1/8 endmill, I'm down to 8 fins and 8 posts. It's a no-go.
The copper to channel ratio has to be 1.5:1, with a fin height of 5mm, unless I try to calculate another fin height which might allow a thinner fin, but I doubt it.
It's going to have to be 1mm, or I'll have to do it by hand. I looked at the machining parameters (
here ), but I'm having a hard time with it. I could calculate the length of all the required cuts, if it's any help.
What's you ropinion on the viability of doing this by hand?
Here's Utabintarbo's interpretation. The fin pattern is different than mine, but let's see if we're talking the same language, so far!
