    Abstract

    Two basically different carbide bit designs, a dagger bit and a standard twist drill, were tested extensively in graphite/epoxy composite material. A commercially available computer vision system was utilized to evaluate hole quality as the bits wore for fraying, delamination, and hole tolerance. Methods and procedures for establishing acceptance criteria using the vision system are given. Based on manual acceptance criteria, vision system criteria were established for fraying and suggested for entrance delamination.
