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.
