Manual Thread Cutting - Siemens SINUMERIK 808D User Manual

As soon as you position the cursor in any of the input fields in the multiple grooves area of the screen, the display changes
from single groove to multiple grooves:
Parameter
Parameter
Distance l3
Number n
Multiple grooves
The machining sequence is as follows:
1. Starting from the current axis position, the first groove is produced as described for the extended grooving function.
2. The starting point for the next groove is then approached taking into account the clearance distance.
3. Another complete grooving cycle is then executed (as described for the extended grooving function).
4. Groove machining and offset then alternate until the number of grooves specified in the "Number n" parameter has been
executed.
5. On completion of the final groove, the original position of the axes before the start of machining is approached diagonally.

Manual thread cutting

Functionality
The manual thread cutting function provides a wide range of options for producing, remachining and recutting longitudinal,
tapered and face threads.
They can be single-start or multiple-start threads.
Note
Any limit stops that are activated should be disabled before starting thread cutting or set to a value outside the traversing
range needed for thread cutting.

Description
Groove offset: This input value determines the offset between several identical grooves
during production.
Number of grooves to be produced. Entering "0" or "1" here has the same effect: A single
groove is produced. When you enter a value of ">1", the appropriate number of grooves is
machined. The input value in parameter "Length I3" defines the necessary offset.
