Detailed Description
2.8 Special handling of tool compensations
Tool Compensation (W1)
Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
2-123
In generic 5-axis transformation with:
• Transformation type 40
The tool orientation is constant with a rotary workpiece, which means that the movement
of the rotary axes on the machine does not affect the temperature compensation
direction.
Temperature compensation in the tool direction also works in conjunction with orientation
transformations (not generic 5-axis transformations) with:
• Transformation type 64 to 69
Rotating linear axis
Note
Temperature compensation can be activated with all other types of transformation.
It is not affected by a change in tool orientation.
The axes move as if no orientation transformation with temperature compensation were
active.
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
Compensation values are restricted to maximum values via machine data:
MD20392 $MC_TOOL_TEMP_COMP_LIMIT[0]
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 the setting data:
SD42960 $SC_TOOL_TEMP_COMP[0]
to
SD42960 $SC_TOOL_TEMP_COMP[2].
The setting data are user-defined, e.g., using synchronized actions or from the PLC. The
compensation values can, therefore, also be used for other compensation purposes.
