curved slot in cylinder

[joshuamschmidt]

Hi there,

How would you cut a curved polar slot into a cylinder like in Cylindrical Milling?
Here a picture for better understanding.


Is something like this even possible with freecad?

Kind regards, Joshua

Hi Joshua, and welcome to the forum!

It's possible, and to get you started, here's one way. I'm sure it could be simplified a bit.
