Custom 4th Axis

Custom 4th axis module for CNC router

This project involved the design and commission of a cutting module that had to be both controlled for tangential cutting, while being offset at an angle of 30 degrees off vertical. The system was designed around the CAD drawing of the cutting module provided by the customer.

The fixture was designed using off the shelf pulleys and belt. The main pulley was then modified to allow for the customers fixture to pass through the system at 30 degrees, while retaining the ability to rotate the fixture in the 4th axis direction as shown in the videos.
