Application of Colding tool life equation on the drilling fiber reinforcement polymers

Fiber reinforcement polymer (FRP) is a hard-to-treat material used in different areas of up-to-date machine building. It has excellent mechanical properties making the material unique in different engineering solutions such as aircraft, aerospace and boatbuilding. The optimization of holemaking operations in FRP is the main aim of the current investigation. This paper presents an approach of defining the most effective cutting data and costs of drilling Saab’s carbon fiber reinforcement plastic (CFRP) using cemented carbide and PCD drills. The experiment results included force and torque monitoring, tool wear defining and holes quality analyzing.
