Achieving Success in CNC Woodworking – In The Loupe

There are a few different ways that you can become successful if you are getting into the CNC woodworking world. One of the most important things is to learn cutting direction in relation to grain patterns. Since wood is anisotropic, the materials properties change depending on the direction that you cut it. You also want to understand the different between a type 1 and type 2 chip. Type 1 chips happen when wood splits ahead of the cutting edge. Type 2 cuts typically happen due to material failure.

Key Takeaways:

  • Cutting along the grain yields less cutting force, but risks a poor surface finish.
  • There are three basic types of wood chips, but more variability occurs when cutting perpendicular to the grain.
  • To reduce tool wear, don’t over-feed, avoid excessive heat, and consider an Amorphous Diamond coating.

“Because of these differences, one must be conscious of the tool path in woodworking and minimize the amount of cutting forces placed on the cutter in order to maximize its tool life.”
