Ever higher demands are placed on the quality and complexity of formed sheet metal parts, whereby the efficiency of the processes may not be affected. Thus it becomes more difficult to ensure process stability. In order to reduce rejected parts it is necessary to improve forming technologies and processes. Closed loop control of process variables with an influence to the quality of a part is a promising approach. Therefor the reliable metrological acquisition of such a parameter is a basic requirement. Forming force respectively force distribution has an influence on component quality and seems to be a suited value. In this paper, a measurement setup and its implementation in a demonstrator is described. First metrological examinations show occurring effects during eccentric load cases and the derivation of spindle forces via additional load paths in the machine frame. This knowledge will be used for the development of a force control.

The article deals with the system identification of drive trains on forming machines. The aim is to analyze the mechanical properties in the frequency domain. A comparison of uncoupled single axes with several axes in a coupling system should provide information on whether different controller parameters or controller structures have to be adapted for both cases. This will be investigated using the example of an electromechanical die cushion on a servo screw press.

MARCY, HTThe Honorable H. Tyler (“Ty”) Marcy:was born in 1918 in Rochester
New York but moved to Baltimore Maryland at an early age where he attended public schools. He is a graduate of the Massachusetts Institute of Technology from which he received both his BS and MS degrees in Electrical Engineering. Subsequent to receiving the latter degree in 1941 he designed and developed gun control systems in the MIT Servomechanism Laboratory until 1946 when he became Associate Director Special Projects Department M. W. Kellogg Company and worked on rocket engine development missile controls and analog air defense systems. In 1951
Mr. Marcy left Kellogg Company to join the IBM Corporation where he remained until 1972 and was employed in various engineering and managerial positions. At IBM his first assignment concerned the bomb/navigational system for the B-52 aircraft. He then moved into commercial development of data processing machines and peripheral devices subsequently being placed in a series of technical management positions which included Assistant Manager of Product Development Corporate Headquarters New York (1956) Manager
Poughkeepsie N.Y. Laboratory (1957) Vice-President
General Products Division (1962) Vice-President
Systems Development Division (1965) and Director of Technology
Corporate Headquarters Armonk N. Y. (1968). His last position was held until 1972 when he left IBM to do private consulting work in engineering management technology and program review. In October 1974 he was appointed by the President to his present office as Assistant Secretary of the Navy for Research and Development. Mr. Marcy has been a member of the Instrument Society of America since 1963
serving as its President from 1971 until 1974. In 1967 he became a Fellow of the Institute of Electrical and Electronic Engineers (IEEE) for his leadership in feedback control and for his significant contribution to the management of technical enterprise. In addition to these professional organizations he is also a member of the
