Tc_Tpg3, $Tc_Tpg4; Tc_Tpg5 - Siemens SINUMERIK 840D sl Function Manual

Change becomes effective
If parameter $TC_TPG2 becomes effective at a later point in time, the values of the tool
parameters of the cutting edges are not automatically aligned immediately. The alignment is
only made the next time that a tool parameter of both cutting edges is changed.
Example
For a grinding tool (T1), the following parameters should be kept the same for cutting edges D1
and D2:
Tool parameter
$TC_DP1
$TC_DP3
$TC_DP4
$TC_DP5
$TC_DP12
$TC_DP13
$TC_DP14
$TC_DP21
$TC_DP22
$TC_DP23
The sum of all parameter codings is entered in parameter $TC_TPG2:
$TC_TPG2 =
4.1.3.4

$TC_TPG3, $TC_TPG4

For grinding-specific tool monitoring (Page 298), thelower limit values of the grinding wheel are
entered in the parameters:
● Parameter $TC_TPG3: Radius [mm] or [inch]
● Parameter $TC_TPG4: Width [mm] or [inch]
Note
For inclined grinding wheels, the minimum radius must be entered in Cartesian coordinates.
4.1.3.5

$TC_TPG5

The actual width of the grinding wheel - e.g. after dressing - is entered in parameter $TC_TPG5.
