The following program blocks assign tools to groups, length and cutter
compensation offset numbers, and expected tool life to specific tools. This
information is assigned to the last group number programmed in a block
using the P-word. The format for these blocks is:
T__ H__ D__ L__;
Where :
Is :
T__
The value entered with the T-word is the tool number of the tool to be assigned to
that group.
H__
The value entered with the H-word is the tool length offset number from the tool
geometry and wear tables that is to be assigned to this tool. The H-word is only
valid if programmed in the same block as a T-word.
D__
The value entered with the D-word is the tool radius number from the tool
geometry and wear tables that is to be assigned to this tool. The D-word is only
valid if programmed in the same block as a D-word.
L__
The value entered with the L-word is used to program the value of the expected
tool life for that tool. The controls interpretation of this is dependant on the value
set with the I-word in this program block. The value programmed with the L-word
remains active for all following tools in that group until replaced with a different
L-word, or a new tool group is programmed with a P-word.
All of the tools should then be programmed for that group in individual
blocks. When all of the tools for that group have been entered, change
groups by programming a different P-word in a block.
When all of the tools for all of the different groups have been entered, end
the execution of editing the tool life management table by programming
either a M02 or M30 end of program blocks or by entering this block:
G11;
This cancels the G10 data setting mode for tool management.
Important: Any information that was contained for a specific tool group
that has been written to using a G10L3 command as described above is
overwritten by the information programmed with the G10 blocks. All
previous data for tool management for any of the groups is lost.
