  • Efficient end-milling by using a combination of off-line feed rate optimization and adaptive force control [Elektronski vir]
    Čuš, Franc, 1953- ...
    A combination of off-line feedrate optimization and on-line adaptive force control is used to maintain a reference peak force during end milling for safe, accurate, and efficient machining. An ... adaptive control system is built which controlling the cutting force and maintaining constant roughness of the surface being milled by digital adaptation of cutting parameters. In this way it compensates all disturbances during the cutting process: tool wear, non-homogeneity of the workpiece material, vibrations, chatter etc. The basic control principle is based on the control scheme (UNKS) consisting of two neural identificators of the process dynamics and primary artificial controller. Design parameters for the adaptive controllers are selected using an experimentally validated machining process model. The adaptive controllers are implemented on an open architecture controlled (OAC) 4-axis NC milling machine, and evaluated using three experimental test cases: prismatic cuts.
