Contour Turning With Manual Machine - Siemens SINUMERIK 840D sl Operating Manual

Working with Manual Machine
16.6 More complex machining
Parameter
The parameters of the input screen forms correspond to the parameters under Automatic (see
Section "Rotate (Page 349)").
Thread cutting
In addition to the functions that are made available by "thread-cutting" under Automatic, you
can insert idle cuts during the machining process under "Manual Machine."
You can interrupt the infeed of the cutting depth during the machining process by inserting idle
cuts, in order to smooth the flanks for example.
Thread re-machining
You can re-machine existing threads, when repairing previously cut threads for example or as
the result of changes that arise from re-measuring (see Section "Thread synchronizing
(Page 117)").
If you want to rework some threads, input the initial plunge depth D0 (inc.). This is the depth
that was reached during a previous machining.
Note
By inputting the plunge depth, you avoid unnecessary idle cuts when reworking the threads.

Contour turning with Manual machine

For contour turning of simple geometric shapes, the same range of technological functions
(cycles) as in automatic mode is available.
782
You can insert idle cuts using the "Idle cut" softkey.
This softkey is only active during machining.
