CNC 4th Axis Basics: Routers and Woodworking

Apr 30, 2013   //   by Bob Warfield   //   Blog, CNC Router, Techniques  //  5 Comments

This is the 4th part of our 4th Axis Basic Series and it covers the use of a 4th axis for a CNC Router and when woodworking.

For the most part, the principals of 4th Axis use with a CNC Router on wood are much the same as the more metal-focused articles that have come before.  You can mount a typical 4th axis on a router table and go to town:

The goal of 4th axis woodworking is typically engraving or columns…

The goals of 4th Axis woodworking are often a little different.  You seldom see 4th axis as a way to access more sides of the part without more setups or as a way to machine more parts in one setup through indexing.  Most 4th Axis woodworking is about continuous indexing in order to do round work such as engraved cylinders of columns of various kinds for architectural work:

This sort of thing is ornamental turning work, and in fact, it is common to refer to the 4th Axis as a “Lathe Attachment” in the CNC Router world.  Here’s a video showing one of my favorite style lathe attachments which involves mounting the 4th axis permanently alongside the table:

The video shows a lot of the typical pineapple and other shapes common to ornamental turning.  Slinging the workpiece alongside the table allows for quite large work to be done and gets away from the Z-travel limitation that many router tables have.

CNCZone has some neat pictures of a DIY lathe attachment for a CNC Router:

His solution for low backlash gear reduction was to build a “gearbox” using timing pulleys.  Clever!

Here’s a video of some 4th axis work on a CNC Router to create a gunstock.  Very cool work:

Some great how-to tips in this video of making a gunstock with a 4th axis…

One of the most exacting and beautiful uses for CNC 4th Axis Woodworking is inlay work, particularly for custom guitars, pool cues, and similar work.  We’ll close with a video of some of this type of work:
