8.6.3.16 (cont) Tbm = the additional stopping time allowed by
the stopping-performance monitor before it
detects stop time deterioration.
Dpf = the added distance due to the penetration
factor as recommended in ANSI B11.19, Annex
D, Figure D.2. The minimum object sensitivity is
stated by the supplier. If beam blankouts or
floating window features are used, these figures
should be added to the object sensitivity figure
before using the chart.
NOTE - Ts + Tc is usually measured by a stop
time measuring device. See also ANSI B11.19,
Annex C and D.
Whenever the press-cycle STOP command or
stopping-performance monitor time or angle
setting is changed, the safety distance should
be recalculated. See also “stopping-
performance monitor” (6.12).
NOTE – No increase in safety distance is
required for fixed blanking applications if the
blanked area is entirely occupied by the material
or fixtures.
In some instances, the use of blanking does not
allow efficient production of certain piece parts.
Horizontal placement of the sensing field, so
that it detects that operator’s waist area, may
present a solution. In this application, the
operator may freely manipulate the workpiece
and operate the press as long as the operator
stands outside of the horizontal sensing field.
The sensing field should be located so that the
operator cannot reach the point-of-operation
prior to interrupting the sensing field and
completion of the stopping action. Where
possible, the sensing field should be of sufficient
depth to prevent the operator from standing
between the field and the point-of-operation.
