3.7 Dwell (G04)
Upon completion of the previous block and in-position check, some time elapses before executing
the next block.
Command format G04 P_ ;
G04 X_ ;
P,X : Dwelling time (sec)
3.8 Exact Stop Check (G09, G61, G64)
Since acceleration and deceleration is applied independently to each axis, the actual
tool path comes inside the programmed path if each axis speed changes greatly
between the former block and the new block in the cutting feed.
The exact stop check is used to solve this problem.
(1) Exact stop check (G09)
Command format G09 ;
This command executes an in-position check at the end of a block before proceeding to the next
block.
(Note 1) G09 is effective only in the commanded block.
(Note 2) In the positioning mode (G00) the exact stop check function is effective
regardless of this command.
(2) Exact stop check mode (G61)
Command format G61 ;
After this command is given, the exact stop check function is effective at the end of each block
until the cutting mode (G64) is commanded.
(3) Cutting mode (G64)
Command format G64 ;
When this command is given, the execution proceeds to the next block without slowing down
between the continuing two blocks. This command is effective until G61 is commanded.
(Note 1) Even during the cutting mode (G64), the exact stop check is executed in the
blocks in the positioning mode (G00) or in the exact stop check mode (G09),
or in the disconnected cutting feed block.
