6.9.6 Machining Attributes
The AWG evaluates the machining attributes for generating the
working plan. The IWG uses the machining attributes as cycle
parameters.
Defining machining attributes
Adjust the working plane (turning contour, front face or lateral
surface, etc.)
Select the attribute type (”Machining attributes” drop-down menu)
Select the contour element (existing attributes are displayed)
Enter/edit the attributes
Soft keys
If holes or patterns and created in a figure (a figure in a figure), TURN
PLUS differentiates between these ”levels.” First select the plane and
the desired contour.

Parameters
B, P:
Starting length, overrun length - no input: The CNC PILOT
automatically determines the length from adjacent undercuts
or recesses. If no undercut/recess exists, the starting length
and overrun length from machining parameter 7 will be used
(see also ”
4.8 Thread Cycles”).
C: Starting angle – if the beginning of the angle is defined with
respect to rotationally nonsymmetrical contour elements
I: Maximum approach - maximum infeed distance
V: Type of infeed
■ (V=0) Constant cross section: Constant cross section for
all cuts
■ (V=1) Constant infeed
■ (V=2) (Remaining) cut division: If the division of thread
depth by infeed yields a remainder, this remainder applies to
the first infeed. The ”last cut” is divided into 1/2, 1/4, 1/8 and
1/8 of a cut.
■ (V=3) EPL method: The infeed is calculated from the pitch
and the speed
H: Type of tool offset of the individual infeeds to smooth the
thread flanks
■ H=0: No offset
■ H=1: Offset from left
■ H=2: Offset from right
■ H=3: Offsets alternates right/left
Q: Number of air cuts – after the last cut (for reducing the
cutting pressure in the thread base)
