Engraving a bowl
Engraving a bowl
I aim to make a hardwood bowl and engrave its interior with a mathematically-defined
set of curves like ones depicted in the attachment. The depicted curves
would be parlayed into v-shaped channels about 1/16" deep.
Should these channels be included in the bowl's model opened by VCarve Pro? Can
they be specified separately? Does VCarve Pro handle engraving in special ways?

Re: Engraving a bowl
After you make your bowl shape, turn the math line into a vector. Project that onto the inner bowl.

Ah excellent. Thanks for the tip Mike. Turning the map line into a vector
Re: Engraving a bowl
Dear Mike,
Many thanks.
Can a "vector" be used to engrave one curve with one depth and another with a different depth?
I'm thinking I'd like a "v" profile. I might want its depth to change, along the curve.

Dear Mike,
Looking at your attachments, curves in mine can sit on the surface of
the basin of a bowl, which they circle.

Re: Engraving a bowl
Not sure what you're asking.
You can V-carve or Profile ON, but need to check "Project toolpath onto 3Dmodel" in either case.
For V-carves, the depth is set by V-bit "pointiness" and distance between the two vectors.
For Profiles ON a vector, you can set a different depth for each vector. I don't know how you could control different depths along the same vector except maybe to play with fluting.
Below is "Profiled"; first example above was V-carved.

Re: Engraving a bowl
Dear Mike,
I'm planning to cut the bowl first and to engrave on it with the
methods you suggested. When I do, I'll post photos here.
I enrolled for the Vectric workshop in Las Vegas, 20-21 October.
That will help me come up to speed, and, by then, I'll have some
experience with CNC routing.
Many thanks,
David

Where is the workshop thru in vegas? I would like to sign up. I'm located in L.A. and desperately need to take a class.
