• Transformation type 64 to 69
Rotating linear axis
Supplementary conditions
Temperature compensation in the tool direction is an option, which must be enabled in advance and is available:
• For generic 5-axis transformation
• For transformation with rotated linear axis for transformation types 64 to 69
Limit values
The compensation values are restricted to the maximum values by the machine data:
MD20392 $MC_TOOL_TEMP_COMP_LIMIT[0] (Maximum temperature compensation for tool length)
To:
MD20392 $MC_TOOL_TEMP_COMP_LIMIT[2]
The limit value default setting is 1 mm. If a temperature compensation value higher than this limit is specified, it
will be limited without an alarm.
SD42960
The three temperature compensation values together form a compensation vector and are contained in setting
data:
SD42960 $SC_TOOL_TEMP_COMP[0] (Temperature compensation with reference to tools)
To:
SD42960 $SC_TOOL_TEMP_COMP[2]
The setting data are user­defined, e.g., using synchronized actions or from the PLC. The compensation values
can, therefore, also be used for other compensation purposes.
In the initial state or when orientation transformation is deactivated, all three compensation values apply in the
direction of the three geometry axes (in the typical order X, Y, Z). The assignment of components to geometry
axes is independent of the tool type (turning, milling or grinding tools) and the selected machining plane
G17
to
G19
. Changes to the setting data values take effect immediately.
Note
Temperature compensation can be activated with all other types of transformation. It is
not affected by a change in tool orientation. The axis move as if no orientation
transformation with temperature compensation were active.
