Description
Start position for the thread in the longitudinal axis (absolute position of the Z axis).
Enter the length of the thread to be created, taking the start position for the thread
("Reference z0") as the starting point. The thread cutting direction is selected by pressing
the "Feed direction" softkey and is indicated in the diagram by means of an arrow. The
choice of whether to produce a left-hand or a right-hand thread depends purely on the
starting direction for the spindle.
Start position for the thread in the transverse axis (absolute position of the X axis in the
diameter). This value applies in the reference point.
End position for the thread in the transverse axis (absolute position of the X axis in the
diameter).
Enter the required pitch in mm/rev.
This parameter is used to set the thread depth. The infeed direction and infeed depth
depend on other parameters ("Intern Extern." and "Linear Degres." softkeys; "Angle"
parameter).
Note:
If the value of the displayed machine date 1108 equals 1 (requirement for automatically
calculating the thread depth) and the input field "t" equals 0, then the thread depth "t" will be
automatically calculated and entered when you enter the pitch value.
The following applies to all male threads:
a thread pitch of 1 mm results in a thread depth of 0.613 mm
•
The following applies to all female threads:
a thread pitch of 1 mm results in a thread depth of 0.541mm
•
The thread depth is adjusted according to an increase or reduction in the pitch value.
Infeed angle; this specifies the angle of infeed during machining. A negative value causes
an alternating infeed.
Enter here the maximum or minimum infeed depth for roughing. The cycle-internal infeed
calculation ensures that this entry value is not exceeded or falls short during thread cutting.
Input of a minimum infeed depth is possible only with degressive infeed.
Note:
The input field for the minimum infeed depth is displayed only if you have selected
"Degressive infeed".
Finishing allowance
In this toggle field you can select whether an internal or an external thread is required. The
selection is indicated by a diagram on the screen.
You can select the machining direction of the thread using this toggle field.
