- Time chart for stopping tapping retraction
Tapping retraction start signal RTNT
Spindle enable signal ENB
Rigid tapping signal RGTAP
Spindle excitation
Retract movement
When tapping retraction is stopped, spindle enable signal is set to 0, in
the same way as for ordinary rigid tapping. Therefore, perform the
sequence for canceling rigid tapping. The CNC also automatically
enters the reset state when tapping retraction is stopped.
Limitation
T
When G code system A is used for a lathe system, you may want to
use an axis parallel to one of the basic three axes as a drilling axis.
In this case, to specify a correct incremental command, use the
extended axis name function to specify X*, Y*, or Z* (* is an
alphanumeric character) as the axis name of the axis parallel to one of
the basic three axes.
Examples
Basic three axes: X, Y, and Z
Parallel axes: XA, YA, and ZA
Signal
Rigid tapping retraction start signal RTNT<Gn062#6>
[Classification] Input signal
[Function] Starts rigid tapping retraction.
[Operation] When this signal is set to "1", the control unit operates as follows:
- Starts rigid tapping retraction.
Rigid tapping retraction completion signal RTPT<Fn066#1>
[Classification] Output signal
[Function] Notifies the completion of rigid tapping retraction.
[Output condition] This signal is set to "1" in the following case:
- Rigid tapping retraction has been completed.
This signal is set to "0" in the following case:
- Rigid tapping retraction start signal has been set to "0".
