Deburring of cross-drilled holes with ball-end cutters—modeling the tool path
- 199 Downloads
Machining of cross-drilled holes generates burrs on the entrance and exit. Deburring of these intersecting holes is challenging due to the limited accessibility. This paper presents a model that creates a tool path suitable for precision deburring of intersecting holes with a ball-end cutter. The presented model is developed with the help of Computer-Aided-Engineering. The tool generates a three-axis travel path related to the intersection geometry of the main and cross hole. The burr is removed and a constant chamfer is machined. The intersection curve is even machined through the main or cross bore. The presented model is verified by means of experiments with three different intersection samples using the material AlSi7Mg.
