Effective cutter diameter and cutter reference height are recorded and will be
required as machine input items of the cutting summary. In case of CBN grind-
ing, only the grinding wheel diameter and the grinding wheel reference height
(grinding wheel plus adaptor) have to be measured and recorded for the ma-
chine grinding summary.

30.9 Teaching the Stock Divider

Stock division is necessary in cases where grinding is applied as a hard-
finishing operation. The basic problem is that Uniflex is just like Coniflex and
Coniface a connected fixed setting process. Although both flanks of one slot
are machined with different summary settings, these settings are part of the
same summary. Also, the move from the left flanks to the right flanks is part of
the same summary. However, in a completing job, the grinding wheel is jogged
into the semi-finished and heat-treated slot (while the de-chucked part is float-
ing), until both flanks touch the grinding wheel. In Uniflex, each flank has to be
stock divided separately and a complex mathematical approach connects the
results of the separate stock divisions in order to achieve a balanced stock al-
lowance.
