Manual machining

5.4 Manual machining using cycles (functions)

Manual Machine Plus Turning

76 Programming and Operating Manual, 06/2009, 6FC5398-6CP10-1BA0

Parameter

Parameter Description

Distance l3 Groove offset: This input value determines the offset between several identical grooves

during production.

Number n 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.

Multiple grooves

The machining sequence is as follows:

1. Starting from the current axis position, the first groove is produced as described under

"Extended grooving".

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 under "Extended

grooving").

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.

5.4.6 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.
