3-sided rotary CNC routing with the Shapeoko – carving a Koi fish
Modifications to the Shapeoko XXL CNC frame and bed were made to accommodate a manual rotary setup that allows for multi-sided 3D carving of objects (along a B-axis) that are too big to fit underneath the X-gantry rail.
To show proof of concept, I carved a Koi fish from a solid stack of plywood with 3-sided CNC routing.
- Meshmixer to create the 3D Koi fish
- Vectric VCarve to generate the tool paths
- UGS Platform to send the Gcode to the CNC
- Everbilt 1 inch square tubes with 5/16″ holes spaced 1″ apart
- 1/4″ steel triangular plates
- 3/8″ bolts (the 5/16″ holes were widened with the drill press)
- 18 mm (3/4″) Sande plywood: 4 sheets of 600×600 mm (4’x4′)
- Surfacing bit to flatten and pocket the stock: WhiteSide #1027A
- Extra long roughing bit: Amana Tool end mill #46590
- Extra long finishing bit: Amana Tool ball nose #46490
