LengthOffsetNumber

Standard Word: ToolLengthOffsetNumber

Variable: Tool.LengthOffsetNumber

Type: Integer

This word/variable contains the information of the length offset number of the currently active tool.

This length offset number obtained from the APT/CL file is first assigned to the “Tool.LengthOffsetNumber” variable. This variable can be used in any script.

In addition, the word “ToolLengthOffsetNumber” is created from this variable. This word is then used in Format Tool Change. or other desired commands.

In Fanuc, Mitsubishi, and Mazatrol controllers (and other controllers that support the ISO format), the tool length offset number is used with the word H. as shown below to activate the length offset value of the specified tool number.

G43 Z100. H12

In the above example, H12 code activates the length offset value of the 12th cutting tool.

The tool length offset number is normally same with the active tool number. However, you can also use different length offset numbers as well.
