Abstract

The method involves ultrasonic stimulation of an outer and/or inner tool with a defined frequency and amplitude. At least the predefined amplitude is held constant within a narrowband frequency range during the drawing process and the minimum amplitude value is 10 microns. The maximum fluctuation range for the amplitude is plus or minus 1 per cent of the set value. AN Independent claim is also included for the following: (a) an arrangement for implementing the inventive method.
