Optimizing workflow for CNC machining complex mesh forms (for computer speed)?

Dear all,
I am using fusion 360 to machine molds that contain complex designs. My current process works, but it has been painfully slow, even on my computer which has 4gb dedicated graphics memory and 16gb ram, six cores.
I'm a graphic designer who is new to the 3d space and don't truly understand the different types of 3d (mesh, tspline, brep, quad, etc). I'm guessing if I can optimize the workflow, I can improve my computer speed.
My current workflow is this
- Create a depth map in Adobe Illustrator
- Import to Fusion as a a 3d surface with Image 2 Surface
- Convert it to Tspline
- Convert it to Brep
- Stitch it to a Solid
- Machine It
I saw a workflow on another forum post, which I can't find at the moment, but this is something I'm trying
- Depth map
- Import to ArtCam 2018 (I can't machine it from here because I want to machine it with the mold design I made in fusion)
- Export to STL
- Import to Meshmixer and then Export to OBJ
- Import to Instantmesh, solve to make quads, Export to OBJ
- Import to Fusion
- Convert to Surface Body - Tsplines? (I had trouble stitching it to a body. I'm confused if that's necessary, if it would improve perforamce or make things worse?)
- Machine
This one seems to machine fine as well, and is a bit faster when it comes to navigate. At least no complete fusion crashes which seems to happen regularly with my other approach. But it seems to take about a minute to open the manufacturing workspace. I am wondering if I am really doing it right.
TLDR: I want to know what is the best format to prepare my model for machining? Second best? Third best?
THANK YOU!
