CNC Router for Woodworking: How to Choose and Set Up
Wood is more demanding than it looks. Grain direction reverses mid-cut and tears the face. Knots deflect the bit. Glue lines in laminated panels machine differently than the surrounding wood. The CNC router for woodworking that handles all of this consistently is not the most powerful. It is the one set up with correct bit geometry, appropriate chip load, and workholding that does not shift when the spindle loads up.
A CNC router for woodworking is a machine and tooling setup configured for wood cutting: high-RPM spindle, working area appropriate for woodworking panel sizes, and bit selection suited to wood fiber.
