This texture below is what the Japanese call naguri, which literally translates to "beaten," revealing its metalworking roots. In wood, the texture is achieved with an adze or gouge.

Woodworker Takurou Seino invented a router jig to produce the texture using electricity.

Leigh Aitken, an Australian design engineer and robotics specialist, has taken it even further. His company, Twig&Bot, specializes in CNC-created furniture and building elements. In the studio, Aitken's been getting the 'bot to produce naguri-like work:

"Experimenting with a parametric random scalloped texture generator I've been working on for the robot. This is the first trial straight off the cutter (no sanding). The lemon scented gum cut incredibly cleanly."

"Some more robot texturing experiments. Full chaos (top) and escalating chaos (bottom). Looking forward to applying these to some furniture pieces and sculptural elements soon."

As of yet there's no finished product, just the teaser below. Aitken's figured out how to produce the texture in a way we haven't seen before: Cylindrically.
