7.3 Manual Synchronous Tapping
7.3.1 Outline
After a synchronous tap cycle is stopped with block stop or feed hold stop, this function carries out tapping by selecting
and moving the drilling axis with manual handle operation.
7.3.2 Command Format
This function is commanded with the same format as for synchronous tapping.
7.3.3 Operation Procedures
The procedures for manual synchronous tapping are described below.
(1) When using the multiple spindle specifications, select the command spindle.
(2) Stop the spindle and servo axis, and select the automatic operation mode.
(3) Execute the synchronous tapping cycle program.
(4) Apply block stop or feed hold stop.
(5) Change to the handle mode. Select and move the drilling axis.
(6) To cancel manual synchronous tapping, execute G80 in the same manner as the normal synchronous tap mode, or
reset the program.
7.3.4 Precautions
(1) When selecting the axis for the handle mode, select the same axis as that commanded in the program.
(2) After executing the program with automatic operation, do not reset the program until manual synchronous tapping is
completed.
The manual synchronous tapping mode will be canceled even if reset is applied in the handle mode.
(3) During manual synchronous tapping, the acceleration/deceleration time constant is the same as normal handle
operation. The return override is also invalid.
(4) When using the multiple spindle specifications, changes to the commanded spindle selection will be validated after
G80; is executed or reset is input to cancel synchronous tapping, and then manual synchronous tapping is started.
(5) The spindle rotation speed during manual synchronous tapping is not clamped by the program's S command or
parameter "#3013 stap1" to "#3016 stap4" (tap rotation speed).
(6) Manual synchronous tapping is valid from the point that synchronous tapping and cutting is carried out once during
automatic operation, and block stop is applied.
(Note)
To validate manual synchronous tapping without carrying out cutting, run the following type of program with no
movement commands.
