This paper presents the development of an intelligent machining center for stable and efficient drilling. An intelligent machining center features the following functions for drilling processes: the tool life detection by on-line estimation of cutting forces, an adaptive cutting force control, and a quick tool retract and adaptive pecking. The integration of these functions is studied in this paper. The proposed intelligent drilling process control schemes are tested in experimentation.

Keywords: intelligent machine tools, drilling, adaptive control, tool life, pecking.
