NEW TECHNIQUES APPLIED TO ADAPTIVE CONTROLLED MACHINING

• The future capital intensive CIM and FMS systems will demand adaptive controlled (AC) machine tools. At the Department of Production Engineering of the Royal Institute of Technology in Stockholm (IMT/KTH) we are continuing the development of an advanced AC turning center. Our approach is to design and use sophisticated sensor systems to measure several features both on-line and off-line in order to obtain sufficient information on the cutting process and make adaptive feedback feasible. The AC system operates at three different levels: advanced process monitoring adaptive control constraint (ACC) adaptive control optimization (ACO). In this paper we give an overview of practical progress and improvements that have been achieved since our contribution to MSTF '87 in Cambridge.1 This includes: a new flexible sensor installation for optical tool wear measurements on-line tool wear estimation based upon a dynamic force sensor applied time series analysis for on-line chatter control real-time control of maching conditions with respect to cutting forces distributed real-time computer system solution.
