8.1 Offset memory
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.
SW 4 and higher
The "Flat D No. structure" is used if tool
management takes place outside the NCK. In this
case, the D numbers are generated with the
associated tool offset blocks without being assigned
to tools.
You can still program in the part program using T.
However, this T does not relate to the programmed
D number.
Several entries exist for the geometric variables (e.g.
length 1 or radius). These are added together to
produce a value (e.g. total length 1, total radius)
which is then used for the calculations.
Offset values not required must be assigned the
value zero.
The individual values of the offset memories P1 to
P25 can be read from and written to the program via
system variable.
