Y1 and Y2 counters differ greatly
If the counters are not identical and present a difference superior to what is
normally tolerated (the press in this case furnishes an angle which varies
from one side to the other of the machine), a test must be made with another
tool in order to determine if the difference comes from the tool itself (tool
badly finished presenting a difference in height along its length) or if the
press is badly calibrated. In the latter case, you must contact the manufac-
turer.
Y1 and Y2 counters identical, but different from REF Y
If the difference between the counters Y1 and Y2 is within the acceptable
tolerance, but the Y1-Y2 value is greatly different from the REF Y value,
you must determine if the difference comes from the height of the die or that
of the punch.
In this case the tool at fault must be corrected so that the REF Y result is
identical to the value of the Y1 Y2 counters.
Modification of the reference for the product
The possibility exists to modify the reference for each tool used for the prod-
uct. This modification is stored with the product.
It is in some ways a reference modification per product tool. It is thus possi-
ble in this case for the same tool pair used for two distinct products, to have a
reference modified positively in the product XXX and to have a reference
modified negatively for the product YYY.
The principle of measure / control is identical to that which is described
above.
To modify the reference in a particular product, you must access the
PRODUCT PUNCHES / DIES page via the main menu, choice 7, and pro-
gram the new reference in the REF Y field which is accessible by the cursor.
All the sequences having the same tooling will be modified.
