CNC Cutting board inlay

On short notice I was requested to make a turtle inlay into a cutting board.

The source image was clipart provided by Google, polished with a bit of Photoshop, added as a part material in CAD and traced as splines to create a CNC toolpath. The toolpath was created twice, once for the base and once for the inlay. An offset of 100 microns was implemented between tool paths to reduce interference and facilitate a clean fit. The stock was machined on a Syil SX3 SNS milling machine.

The black walnut inlay is roughly 8mm deep into silver maple. While the materials were chosen for contrast, silver maple does not machine well even with a sharp tool and leaves a fuzzy fibrous edge.  The entire project, from image source to glue up, was completed in under two hours.
