Because approximately 36% of all machine hours (40% of CNC) are spent performing hole-making operations, the use of high-performance drilling systems can significantly reduce hole-making costs and increase the efficiency of the drilling operations. This chapter first presents the basics of a system approach to the design of high-efficient drilling operations, arguing for the coherence of the components of drilling systems. It then reveals the principal steps in the design of drilling systems. The main emphasis is placed on the design/selection of the proper tool for the application.
