Summary

In this investigation, effects of a vibration on the blank holder in cup drawing were studied. The vibration on the blank holder was given by the cam mechanism, and the blank holder frequencies were varied from 10 Hz to 45 Hz. An aluminum sheet was used as the test material.

Experimental results were as follows: a limiting drawing ratio (L.D.R.) increased with increase of the frequency, that is, the L.D.R. with the conventional method was 2.00, whereas such ratios at frequencies 11.7, 21.5, 29.2, and 45.0 Hz were 2.175, 2.325, 2.375, and 2.425 respectively, further a punch load and a thickness strain in the drawing cup decreased with increase of the frequency.
