DiameterComp
=============================================


**Standard Word:** ToolDiameterComp

**Variable:** Tool.DiameterComp

**Type:** Enum

There are 3 different states defined for tool diameter compensation. These are as follows:
Left(G41),
Right(G42) and
Cancel(G40).

These different states are defined inside the “ToolDiameterComp” word.

The active tool diameter compensation state is obtained from the “CUTCOM/” line (or similar expressions in some other CAMs) in the APT/CL file and the current state of the diameter compensation mode is assigned to the “Tool.DiameterComp” variable. This variable can be used in any script. When used in a script, the “Tool.DiameterComp” variable returns the strings "Left", "Right" or "Cancel".
The word "ToolDiameterComp" is also created from this variable. For each diameter compensation mode, the G codes (G41, G42 and G40) can be defined in the "Edit" page of this word. After that, this word is used in different commands such as :ref:`Format Motion Linear<Format Motion Linear>`., :ref:`Format Motion Circular<Format Motion Circular>`. and :ref:`Format Motion Helical<Format Motion Helical>`. and the relevant G code is printed into the NC program automatically.
