The Walnut: CNC

After an initial test on the walnut to establish the surface finish I wanted on the walnut, we build a large jig for the walnut to fit into to ensure it was stuck now to the bed properly.

I then wrote the toolpath for the walnut with the following settings-

Stepover 1
Stepdown 2
Feed rate 1.8
Plunge rate 1
Spindle speed 20000
Tool number 1

Below is a short video of the process.

The outcome is really nice, I am really pleased with how the form looks in walnut.

Whilst the surface finish is fairly good, I still have quite a lot of finishing work to do as the tool did feather up the wood a bit.
