2.3 Changing the tool compensation
This function can change the tool compensation identified by the offset number
corresponding to T code specified during automatic operation. If there is no valid tool
compensation (for example, when no T code has been issued since cycle start), no tool
compensation change takes place even when axis movement is made manually.
Linear axis movement can change the tool compensation. Rotation axis movement
cannot change it. When the tool compensation is being changed, manual feed cannot
cause movement along more than one axis at a time.
Example
The compensation value set at Z-axis of the offset number 10 becomes
54.700 + (-2.583) = 52.117 mm under the following conditions:
• Specified T code: T0110
• Value set at Z-axis of the offset number 10: 54.700 mm
• Amount of movement caused by manual feed along the Z-axis:
-2.583 mm
• Parameter ATP (No.5041#1)=0
2.4 Changing the workpiece origin offset
This function can change the workpiece origin offset of an individual axis of the
workpiece coordinate system corresponding to G54 to G59 or G54.1P1 to P48
specified during automatic operation. There is a currently valid workpiece
coordinate system. So, axis movement made by manual feed causes the
workpiece origin offset of that workpiece to be changed. In addition, movement
along any axis (regardless of axis types, such as linear axes or rotation axes) can
change the workpiece origin offset. Moreover, manual feed can be made along
more than one axis at a time, when the workpiece origin offset is being changed.
