_T
INT
Internal T number of tool
If this parameter is not specified, or if its value is 0, the tool stored in _STAT is used.
If the value of this parameter is -1, the T number of the active tool is used. It is also
possible to specify the number of the active tool explicitly.
Note
If _STAT is not specified, the current status is used as the tool environment. Since _T = 0
refers to the T number saved in the tool environment, the active tool is used in that
environment, i.e., parameters _T = 0 and _T = -1 have the same meaning in this special
case.
_D
INT
Cutting edge of the tool. If this parameter is not specified, or if its value is 0, the D
number used is based on the source of the T number. If the T number from the tool
environment is used, the D number of the tool environment is also read, otherwise the D
number of the currently active tool is read.
_DL
INT
Number of the local compensation. If this parameter is not specified, the DL number
used is based on the source of the T number. If the T number from the tool environment
is used, the D number of the tool environment is also read, otherwise the D number of
the currently active tool is read.
Any rotations and component exchanges initiated by the adapter transformation, toolholder
with orientation capability and kinematic transformation, are part of the tool environment.
They are thus always performed, even if the corresponding length component is not
supposed to be included. If this is undesirable, tool environments must be defined, in which
the corresponding transformations are not active. In many cases (i.e., any time a
transformation or toolholder with orientation capability is not used on a machine), the data
sets stored for the tool environments automatically fulfill these conditions, with the result that
the user does not need to make special provision.
