2.8 Special handling of tool compensations
Tool Compensation (W1)
2-126 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
NC program
Temperature compensation values in the NC program
The compensation values assigned to axes X and Z are not zero and are applied for
temperature compensation with respect to tool length. The machine axis positions reached in
each case are specified as comments in the program lines.
SD42960 TOOL_TEMP_COMP[0] = -0.3 ; First compensation value
SD42960 TOOL_TEMP_COMP[1] = 0.0 ;
SD42960 TOOL_TEMP_COMP[2] = -1.0 ; Second compensation value

With the exception of block N40, temperature compensation always acts in the original
directions, as the tool is pointing in the basic orientation direction. This applies particularly in
block N50. The tool is actually still pointing in the direction of the X axis because the B axis is
still at 90 degrees. However, because the transformation is already deactivated, the applied
orientation is parallel to the Z axis again.
MD20390 TOOL_TEMP_COMP_ON = TRUE ; Temperature compensation active
Option ; Activate option
MD32750 TEMP_COMP_TYPE[ AX1 ] = 4 ; Compensation in tool direction
MD32750 TEMP_COMP_TYPE[ AX2 ] = 4 ; Compensation in tool direction
MD32750 TEMP_COMP_TYPE[ AX3 ] = 4 ; Compensation in tool direction
