How to Make a Wood Shell Bowl with a CNC Router / CNC Woodworking


September 2020 Update: I’ve been refining this process a lot! Be sure to check out my more complete tutorial on how I create bowls on my CNC machine: CNC Woodworking Drip Bowl Tutorial on YouTube

Hi everyone! I decided to experiment with more organic bowl shapes that can’t be created on a lathe. My last CNC wood bowl was based on a square and pyramid shape and this one is inspired by a shell you might find in the ocean. Hopefully the will inspire some people to take on some CNC woodworking projects.

First off, download the CAD/CAM files from below so you can follow along. The CAD was done in Fusion 360 and the CAM is specific to my Tormach PCNC 1100 machine. You are free to download the files and make this bowl for personal use only. Please contact me for licensing if you want to commercially make this bowl.
