Abstract
This paper describes the method to display the tool trajectory using augmented reality techniques. First, the paper overviews the prototype of a computer controlled dental milling machine (DMM) under development of this study. The paper shows how to use DMM in dental treatment, covering its basic functions such as joystick-based control, NC code-based control, manipulation recording, and replay operation for the manual manipulation. Then the paper presents superimpose of trajectory of cutting tool path and virtual objects over the physical model using the mixed-reality techniques. The discussion and future direction will be followed.
