Another example of why CNC is cool

This curved molding piece is part of a sign project where I’m experimenting with some design and finishing techniques. This is not 3-D carving requiring a 3-D model. It only uses a simple molding tool path to follow a curved vector (line). I drew the cross section of the molding profile, assigned it to follow the curve, and used both a 1/4” spiral bit and a 1/8” ball nose bit to do the carving. The final molding piece is 2” wide x 16” long x 3/4” max thickness, made out of select pine from Home Depot.

A frame could be made the same way by following a square or rectangle shape, creating crisp mitered corners without the need for any miter cuts, glue, or clamps.
