B±5.5
Defines the depth of the threading passes and it is given in radius.
If a positive value is programmed, the depth of each pass will depend on the number of the
corresponding pass.
This way, the penetrations along the Z axis are:
If a negative value is programmed, the passes will have the same depth with a value equal to
the one programmed (B).
This way, the penetrations along the Z axis are:
If programmed with a 0 value, the CNC will display the corresponding error message.
Regardless of the sign assigned to "B", when the last roughing pass (before finishing) is smaller
than the programmed amount, the canned cycle will run a pass equal to the residual stock.
E±5.5
It is related to parameter "B".
It indicates the minimum value to be reached the penetration pitch when parameter "B" has been
programmed with a positive value.
If not programmed, a value of 0 is assumed.

Defines the safety distance and it indicates at what distance, along Z, from the initial point must the
tool be positioned in the approach move.
The return to the initial point after each pass will be carried out maintaining this distance (D) from
the programmed section.
If the programmed value is positive, this withdrawal will be performed in round corner (G05) and
if negative, in square corner (G07).
If not programmed, a value of 0 is assumed.
