Tool offsets

8.1

Offset memory

8.1
Function
Structure of the offset memory
Every data field can be invoked with a T and D number (except "Flat D No."); in addition to
the geometrical data for the tool, it contains other information such as the tool type.
Flat D number structure
The "Flat D No. structure" is used if tool management takes place outside the NCK. In this
case, the D numbers are created with the corresponding tool compensation blocks without
assignment to tools.
T can continue to be programmed in the parts program. However, this T has no reference to
the programmed D number.
Machine manufacturer
User cutting edge data can be configured via machine data. Please refer to the machine
manufacturer's instructions.
