I just updated this file to include all miter angle cuts between 30 degrees and 166 degrees.

Description of downloadable file:
This model contains multiple layer names and lines representing the cut path of a 3/8" ball end mill along the edge of a part of thickness 0.499 inches. It allows carpentry joints at all angles between 30 and 166 (as measured through the acute angle of the matching faces) An example of the application is in the file and shows how to use the pre-grouped angle patterns. The angle patterns show their z azis placement. Steps: 1 measure part angle, 2 select angle, 3 move and place as shown in example, 4 stretch the grouped miter angle pattern so it goes slightly ( 1/2" diameter of 3/8" bit) of part. The layer name convention is directly compatible with Thermwood Control Nesting Software driven machines with 0.375 being end mill and 0.374 being ball end mill in tool setup. The angle patterns are grouped and inter-related through the sketchup component feature (change one line name, and all other cut paths for all other angles auto-update) There is an additional 3/8" end mill clean up pass for steep angle miters greater than 102 degrees. The drawing of the ball end mill and end mill bit was done by others (as noted).
