Note
The cutting edge data for D1 and D2 of a selected grinding tool can be chained, i.e. if a
parameter in D1 or D2 is modified, then the same parameter in D1 or D2 is automatically
overwritten with the new value (see tool-specific data $TC_TPG2).
Definition of additional parameters $TC_DPC1...10
For user-related cutting data, additional parameters:
$TC_DPC1 to 10
can be defined independently of the tool type using general machine data:
MD18096 $MN_MM_NUM_CC_TOA_PARAM
Changes to the MD take effect after POWER ON and will lead to initialization of the
memory (back data up beforehand if necessary!).
Automatic changeover between grinding wheel offset left and right does not take place
during contour grinding. This changeover must be programmed.
