Basic value and wear value
The resultant values are each a total of the basic value and wear value (e.g. $TC_DP6 +
$TC_DP15 for the radius). The basic measurement ($TC_DP21 – $TC_DP23) is also added to
the tool length of the first cutting edge. All the other parameters, which may also impact on
effective tool length for a standard tool, also affect this tool length (adapter, orientatable
toolholder, setting data).
Limit angles 1 and 2
Limit angles 1 and 2 each refer to the vector of the cutting edge center point to the cutting edge
reference point and are counted counterclockwise.
3.13.2 Additive offsets
3.13.2.1 Selecting additive offsets (DL)
Additive offsets can be considered as process offsets that can be programmed in the
machining. They refer to the geometrical data of a cutting edge and are therefore a component
of tool cutting data.
Data of an additive offset is addressed using a DL number (DL: Locationdependent; offsets
regarding the location of use) and entered via the user interface.
