Single-Pass Drilling of Composite/Metallic Stacks 2001-01-2573
Drill geometry specifications, per industry standards, are insufficient to control a single-pass drilling process. For close tolerance holes, those having a tolerance band of 0.003 inch, cutting tool geometry must have additional requirements defined to ensure consistency in manufacturing processes. This paper addresses key characteristics and inspection methods required to control cutting tool performance and to ensure repeatability in an aerospace manufacturing environment.
The primary intent of this paper is to raise the awareness in industry that higher quality product is required by end users.
