L Finishing stock.
It defines the finishing stock at the bottom of the thread. If not programmed, a value of 0 is
assumed.
A Maximum penetration step.
Defines the maximum penetrating pass of the thread. If not programmed or programmed with
a 0 value, it will run a single pass up to the finishing stock.
E Approach distance.
Approach distance to the thread entry.
C=0 C=1 C>1
Q Thread entry (start) angle.
Angle (in degrees) of the segment formed by the center of the hole and the thread entry point
with respect to the abscissa axis. If not programmed, a value of 0 is assumed.
Basic operation
1 Rapid movement to the center of the hole (X, Y).
2 Rapid movement to the reference plane (Z).
3 Rapid movement of the plane axes to the thread entry point (it only makes this movement
if parameter E has been programmed).
4 Rapid movement to the thread entry point coordinate along the longitudinal axis.
5 Rapid movement to the thread entry point (movement interpolated in 3 axes).
6 Thread entry with a helical movement tangent to the first helical threading path.
7 Making the thread according to the value of parameter C.
C=0 Helical movement, in the direction indicated in parameter J, to the bottom of
the thread (the movement will only be one revolution). Then, helical thread
exiting movement, tangent to the previous helical path.
It must be borne in mind that in the exit tangent to the helical path, the exit
point will exceed the coordinate of the bottom of the thread along the
longitudinal axis.
C=1 Helical movement, with the pitch and direction given in parameter J, to the
bottom of the thread. Then, helical thread exiting movement, tangent to the
previous helical path.
It must be borne in mind that in the exit tangent to the helical path, the exit
point will exceed the coordinate of the bottom of the thread along the
longitudinal axis.
C=n Threading loop until reaching the bottom of the thread.
Helical movement, with the pitch and direction given in parameter J, (the
movement will be one revolution).
Helical thread exiting movement, tangent to the previous helical path.
Rapid movement to the Z coordinate of the thread entry point of the next
threading path.
It must be borne in mind that in the last helical exit, the exit point will exceed
the coordinate of the bottom of the thread along the longitudinal axis.
8 Rapid movement to the reference plane (G99).
9 Repetition of steps 3 to 8 until reaching the depth of the finishing stock.
10 Repetition of steps 3 to 8 until reaching the bottom of the thread.
11 Rapid movement to the reference plane (G99) or to the starting plane (G98).
