Popis: Drilling process is commonly used in the aerospace industry to mount fasteners. In some cases, the drilling process is combined together with countersinking (CSK) process using a single drill bit. Improper setup of this process affects the quality of holes, thus deteriorating the process capability. Therefore, the objective of this study is to investigate an appropriate technique to improve CSK diameter repeatability and process capability. CSK drilling with seating-point outperformed without the seating point with regards to its process repeatability. Seating-point underneath the CFRP plate tends to minimize the deflection thus improve CSK diameter repeatability.
