Abstract 

This paper presents a method to minimize burr formation in drilling intersecting holes using Design of Experiments (DOE). Three controllable parameters: tool geometry, speed and feed, were optimized through iterative DOEs. An 88 % reduction in burr size was obtained using the final optimal conditions from DOE II.

Keywords: burr formation, design of experiment, drilling, drill geometry.
