As shown in Table 14.2(a), the travel distance of the tool is increased or
decreased by the specified tool offset value.
In the absolute mode, the travel distance is increased or decreased as
the tool is moved from the end position of the previous block to the
position specified by the block containing G45 to G48.

If a move command with a travel distance of zero is specified in the
incremental command (G91) mode, the tool is moved by the distance
corresponding to the specified tool offset value.
If a move command with a travel distance of zero is specified in the
absolute command (G90) mode, the tool is not moved.
