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.
