Schnieders, S. and Eickhorst, D., "Implementation of High-Performance Vibration Assisted Drilling Process for Drilling and Fastening Systems," SAE Technical Paper 2016-01-2096, 2016, doi:10.4271/2016-01-2096.
Drilling of high-strength titan material and composites in combination creates complex challenges in order to achieve required productivity and quality. Long spiral chips are characteristically for the titan drilling process, which leads to e.g. chip accumulation, high thermomechanical load, surface damages and excessive tool wear.The basic approach is the substitution of today’s peck drilling as current solution to this problem and the implementation of a vibration assisted drilling, so called micro-peck-drilling-process, to generate a kinematic chip breakage in a significant more efficient way.To meet perfectly the requirements regarding rates, quality and automation level, Broetje-Automation as system integrator has investigated and developed the implementation of different alternative high-performance systems and methods to approach the optimal oscillation movement of the tool. In addition to the analysis of the system, the process has been investigated to complete the development.
