So how did you create the 3D bowl? Very interesting.

Very nice... I've got some fluted shallow bowls/dishes up on my Etsy store.

I'm assuming you did the inside (with fluting paths) first, then flipped it over. May I ask how you located it & held it in place while you machined the bottom?

Thanks for posting,
Chris

Size is 12x12x3.

Chris is correct, the inside was created with a fluting toolpath, 18 flutes cut with a 2" surface planing bit,
starting at the outside and meeting in the center. Each flute is rounded, ramps over the complete length
and the flute depth is 2 1/4".

We drilled 4 holes in the corners, then drilled 4 holes in the same location in the wasteboard, then put
dowels in the holes to get it in the same position.

Outside was cut with 4 differently angled V-bits, each cut further out. 150, 120, 90, and 60 degrees.

On the bottom, there were 3 passes cut with the 150 degree bit, each further out and a deeper
depth to create a straight line, then 3 more passes with the 120 degree bit. Then 1 with the 90
and 1 with the 60.

I just spent 10 days visiting my Dad and we did CNC projects every day. It worked out
perfectly because it was too bloody cold to do anything else!

Andy, thanks for posting your process. I didn't think of using an end mill type bit for my bowl & dish work. The few I've done have used a ball mill. I'll give it a go with an end mill and see how that works for me.

Thanks!

Chris, the End Mill Shaped bit with the really large diameter is what creates the scallops. The diameters of the
cuts of the 2" surface planing bit (the largest I could get) overlap to create the scalloped shape. That pattern
was cut with 18 flutes. With a ball nose, the same pattern would have taken hundreds of flutes.

Should I post the .crv file?

Andy,
Nice bowl!
I like the method you used for rounding off the bottom.

Yeah, I understand the relationship to your flute size & shape with the end mill you used. The fluted bowls & dishes I've made did have LOTS more (and smaller) flutes. The one in the pictures below is 5.5" and used a .375" ball nose with 72 flutes.

I'd like to see your .crv file, and I bet other's would too. It would be interesting & educational to see how the tool paths relate to the final piece.

Thanks!
Chris

Wow, that 72-flute ash heart is gorgeous!
