Inlay project

Post by RobCee » Sat Aug 08, 2015 3:06 pm

I finally got around to trying some inlay work using V-Carving techniques. Here is the result and a bit of the work in progress (click the images for higher resolution).

Finished with danish oil:

----------------------------------------------------------------
Machining information:

The Oak board was 22mm thick and around 290mm x 160mm, the Mahogany board was 19mm thick and slightly smaller at 280mm x 150mm.

Material was faced flat over the area to be worked using a 1/4" shank 16mm diameter router cutter for speed. This ran at 12,000rpm at a feed rate of 1200mm.min and a depth of 0.5mm. The oak board was very bowed, so it took four passes to clear a flat piece.

Regular cutting was done with a 1/4" shank, 1/8" cutter running at 24,000rpm at a feed rate of 1000mm/min and 2mm depth of cut

V-Carving was done with a 1/8" 60degree cutter also running at 24,000rpm at a feed rate of 500mm/min and 1mm depth of cut

The cutting took around an hour to complete each piece, then they were separated from their boards and glued together. Finishing them took longer than the making!

That's really nice. What vcarving software did you use?

beautiful stuff... i'm also interested in knowing what software you used, and also what settings you used for the various depths, prismatic overcut, etc.

I used V-Carve Pro and the technique outlined in this document.

My settings were:
Inlay Flat Depth = 2.0mm
Inlay Start Depth = 1.5mm
Inlay Pocket Flat Depth = 2.5mm

The prismatic overcut is automatic with V-Carve because you give it a start depth and it assumes that there is no material above that level, by projecting the cut line down by that amount, the angles just work out nicely.
Once you work out the values for the depths, it is pretty simple. This was my second attempt at it, you need a sharp cutter for the fine detail though.

Beautiful...thanks for the link to the document!!
No longer have a Shapeoko, but use a machine of my own design...
