DEVELOPMENT OF ADAPTIVE CONTROL TECHNIQUES FOR NUMERICALLY-CONTROLLED MILLING MACHINES.

Abstract

Phase III of a program directed toward the development of adaptive control techniques for numerically-controlled milling machines is described, and plans for Phase IV are reviewed. A complete prototype adaptive control system was fabricated and tested in conjunction with a profile-type milling machine. Results of the tests verified that all portions of the system were operating satisfactorily. The metalcutting tests begun in Phase II were extended to include additional workpiece and cutter materials, and to further investigate possible correlation of tool life and surface microfinish with measured machining variables. The collection of data for these tests was enhanced by redesigning the spindle instrumentation system to obtain improved reliability and rigidity. (Author)
