Tool Control Functions
Chapter 20
20-23
Important: G10 blocks may not be programmed when TTRC is active.
CAUTION: Any time that a G10L3; block is executed the
control automatically clears all information that is in the
management tables for all tools and tool groups.
Any time after the G10L3 command, parameters may be programmed to
enter what tool group is being entered, the type of tool life measurement
that is being used, and the tool life threshold percentage. The format for
this block is:
P__I__Q__;
Where :
Is :
P__
The value entered with the P-word is used to program what tool group number is
being edited. The following blocks assign tools to that tool group.
I__
The value entered with the I-word is used to program the type of tool life
measurement that is to be used for all the tools in that group. I0 sets a type of
time, I1 sets a type of number of uses, and I2 sets a type of distance. See
section 20.5.1 for details. If more than one I-word is programmed for a tool group
the control uses the last programmed I-word for that group. If no I-word is
programmed for a group the control uses I1 as a default value.
Q__
The value entered with the Q-word is used to program the threshold percentage
for that tool group. Enter the percentage of the total expected tool life that
causes the tools in the group to be classified as old. See section 20.5.1 for
details on threshold percentage. If the Q-word is not programmed in a block the
control uses a default value of 80%. If more than one Q-word is programmed for
a tool group the control uses the last programmed Q-word for that group. If no
Q-word is programmed for a tool group the control uses Q80 as the default value.
