CAM for CNC code for cutting trispokedovetiles (3-spoke dovetailing tiles)

[Peter Dow]

I thought that this was quite an interesting design, so I looked at recreating it with Fusion 360:

I have attached the F360 model. I have used the F360 User Parameter feature to allow the user to tweak dimensions easily. Outer_circle_dia gives the diameter of the tile. Hex_spacing gives the centre-centre spacing of the hexagons that make up the underlying structure. Corner_rad gives the fillet radius on internal and matching external corners. Yes, I tried to fix the "sharp internal corner" problem.

Obviously, you can just go straight from design to gcode using F360 CAM and choose your own cutter diameters. You could, if you wanted, export a DXF version of the basic sketch. Note that because I was having serious problems in F360 in trying to draw one spoke and then use a circular pattern at sketch level, I actually extruded one spoke and then built up the tile using a circular pattern at the solid body level. This might make sense to someone with F360 experience, and if any of those people can point me at what was going wrong, please do so!

Thank you for your interest Neale.

I downloaded Fusion 360 to investigate your drawing but I didn't see any convenient way to get the full variety of trispokedovetile shapes, as is illustrated by the animation on my webpage, where CIRCLE varies from 100% to 150% of HEXAGON.
