14.27.5.3 Tool Length Offset Amount

The length (tool length offset amount) from the tool tip to the holder edge is required for the tool to move keeping the
positional relationship between a workpiece and the tool tip in "Rotation with the tool tip as the center".
Use an offset amount of the tool length offset command (G43/G44) for automatic operation.
Use the machining parameter "#8043 Tool HDL FD OFS" for manual feed.
When the tool length offset amount is "0", the tool moves keeping the positional relationship between a workpiece and the
holder edge in "Rotation with the tool tip as the center". Therefore, if a tool is actually mounted, interference with a workpiece,
etc. may occur.
