Wear module allows
for the prediction for the need of tool regrinding in hvo
steps. During the first step, one can compute the tool radius
variation versus the number of blanking cycles. During the
second step, it possible to predict the burr height
corresponding to the number of blanking cycles. The wear
algorithm for predicting the tool wear inEuence and
determining the need for regrinding is very helpful to
improve the reliability of the shearing tool and to determine
the tool repair or change.
