Tool offsets

3.13.1

Offset memory

Structure of the offset memory
Every data field can be called with a T and D number, and contains not only the geometric
specifications for the tool but also further entries, such as the tool type.
User cutting edge data
User cutting edge data can be configured via machine data. Please refer to the machine
manufacturer's instructions.
Tool parameters
Note
Individual values in the offset memory
The individual values of the offset memory P1 to P25 can be read and written by the program
via system variables. All other parameters are reserved.
The tool parameters $TC_DP6 to $TC_DP8, $TC_DP10 and $TC_DP11 as well as $TC_DP15
to $TC_DP17, $TC_DP19 and $TC_DP20 have another meaning depending on tool type.
