Decorative V cutting and chamfers

[WillAdams (William Adams (Carbide 3D))]

As requested on support…

Given a design:

where one wants decorative V cuts along all the geometry, one would start by selecting all the interior elements:

and assigning a No Offset Contour toolpath to the desired depth:

which previews as:

For the outline:

It would be best to close this geometry using “Join Vectors”

or, just re-draw it:

Boolean Union:

OK

Since the tool is 90 degrees, the added depth/offset are the same so offset to:

Apply:

Apply a No Offset Contour to the greater depth:

which previews as:

For cutting out the design it will be necessary to use a #201 since the stock thickness (0.75") is greater than the flute length of a #102 — best practice is to offset by tool diameter plus 10%:

Apply

Select the offset and original geometry:

and assign a Pocket toolpath to tab height or the penultimate pass:

Then add tabs to the original geometry:

Assign an outside Contour toolpath which starts at the bottom of the preceding pocket and finishes the cut:

It will be necessary to use a chisel or file to clean up the corners.

Thanks, William.

I certainly wasn’t expecting all you did.

Bueno and gracias for the tutorial.

My pleasure! It’s what we do here.

Alternately, you can lean into the rounding:

Draw a rectangle the size of the rounding:

and use the Centerpoint to position it:

and one corner to draw a circle for the rounding:

Then use Trim Vectors and Node Editing to combine things:

OK

Node Edit:

Cut Vector

Select the excess vectors:

d to delete

Done

Select the two geometries:

Join Vectors:

Yes

Repeat at the other intersections, then edit or re-draw the central geometry:

Or, better still, use the Corner tool which is intended for such usages:

Just adjust the radius to what is desired and click on the ones which need rounding.

(It will still be necessary to adjust the interior geometry)
