Multiple Tapping - Siemens SINUMERIK 802D sl Programming And Operating Manual

Manual machining
5.4 Manual machining using cycles (functions)
Parting
The machining sequence is as follows:
1. Starting from the current axis position, the first calculated parting position is approached
2. Execute the depth infeeds as a roughing motion in the transverse axis (X axis): each
3. When the base of the groove is reached, the tool is withdrawn from the material at the
4. Finally, the original position of the axes before the start of machining is approached

Multiple tapping

Functionality
The "Multiple parting" function is a subfunction of the "Groove cycle - multiple" function.
Operating sequences
You activate the "Multiple parting" function by assigning the following parameters in the
screen for "Groove cycle - multiple":
Parameter
Groove width
Chamfer/radius
Chamfer/radius
Note
The chamfer/radius (CHF/RND) parameters must be set to "0", otherwise the cycle cannot
calculate the contour and displays an error message ("Groove form not defined correctly").

(diagonally) in both axes, taking into account the clearance distance.
infeed depth is calculated internally so that firstly the setting "m1" is not exceeded and
secondly the infeed distance is kept uniform until the base of the groove (parting depth) is
reached. After each infeed, the tool is retracted by the clearance distance for chip
breaking.

diagonally.
Description
l1 Groove width "I1" must be identical to the tool width for the "multiple parting" function.
F1 This value must be deactivated with a setting of 0.0 for "multiple parting".
F2 This value must be deactivated with a setting of 0.0 for "multiple parting".
