• Setting data:
SD42935 $SC_WEAR_TRANSFORM (transformations for tool components)
• Setting data:
SD42940 $SC_LENGTH_CONST (change of tool components on change of planes)
• Setting data:
SD42950 $SC_TOOL_LENGTH_TYPE (allocation of the tool length components
independent of tool type)
•
The orientation component of the current complete frame (rotation and mirroring, no work
offsets or scales)
• The orientation component and the resulting length of the active toolholder with
orientation capability
•
The orientation component and the resulting length of an active transformation
•
In addition to the data describing the environment of the tool, the T number, D number
and DL number of the active tool are also stored, so that the tool can be accessed later in
the same environment as the
TOOLENV
call, without having to name the tool again.
Not in the tool environment
The value of the machine data determines whether the adapter length or the tool base
dimension is included in the tool length calculation:
MD18104 $MN_MM_NUM_TOOL_ADAPTER (tool adapter in TO area).
Since a change to this machine data only takes effect after Power On, it is not saved in the
tool environment.
Note
Resulting length of toolholders with orientation capability and transformations:
Both toolholders with orientation capability and transformations can use system variables or
machine data, which act as additional tool length components, and which can be subjected
partially or completely to the rotations performed. The resulting additional tool length
components must also be stored when
TOOLENV
is called, because they represent part of
the environment, in which the tool is used.
