4.1.3.8

$TC_TPG9

Parameter $TC_TPG9 is used to define to which tool parameters the following functions should
refer:
● Grinding-specific tool monitoring (Page 298)
● Constant grinding wheel peripheral speed (GWPS) (Page 301)
Examples:
$TC_TPG9 = <value>
4.1.3.9

$TC_TPG_DRSPATH and $TC_TPG_DRSPROG

Parameter $TC_TPG_DRSPATH (directory path to the dressing program) and
$TC_TPG_DRSPROG (dressing program) allow a dressing program to be assigned to a
grinding wheel. In turn, this allows a generally valid dressing procedure to be created, in which
the dressing program is executed using an indirect program call.
Example:
Program code
...
$TC_DP12[GETT("GRINDING_WHEEL",0),1]= $TC_DP12[GETT("GRINDING_WHEEL",0),1] - 0.01

Definition of additional parameters $TC_TPC1 ... 10

For user-specific tool data, the additional parameters $TC_TPC1 to $TC_TPC10 can be set up
independent of the tool type via the following memory-configuring machine data:
