The following blocks have no tool movement. In these blocks, the tool
will not move even if tool nose radius compensation is effected.
1. M05 ; M code output
2. S21 ; S code output
3. G04 X10.0 ; Dwell
4. G10 P01 X10 Z20 R10.0 ; tool nose radius compen–
sation value setting
5. (G17) Z200.0 ;Move command not included
in the offset plane.
6. G98 ; G code only
7. X0 ;Move distance is zero.
Com-
mands 1
to 6 are of
no
move-
ment.
When a single block without tool movement is commanded in the offset
mode, the vector and Tool nose radius center path are the same as those
when the block is not commanded. This block is executed at the single
block stop point.

However, when the move distance is zero, even if the block is commanded
singly, tool motion becomes the same as that when more than one block
of without tool movement are commanded, which will be described
subsequently.
