Protection zones for drilling and milling operations
TURN PLUS machines drilling and milling contours on transverse
surfaces (front or rear face) if:
(Horizontal) distance to transverse surface > 5 mm, or
Distance between chucking equipment and drilling/milling
contour is > SAR (SAR: See user parameter).
If jaws are used for clamping the shaft at the spindle, TURN PLUS
accounts for the Cutting limit, outside O.
Machining information:
Chucking the workpiece at the spindle: Ensure
that the area, where the blank part is chucked, is
premachined. Otherwise, the cutting limitation might
adversely affect the machining strategies
Machining of bars: TURN PLUS does not control
the bar loader and does not move the tailstock and
steady rest components. Workpiece adjustment
between collet and dead center during machining
operations is not supported.
Transverse machining:
Please note that the entries made in the
Machining sequence apply to the complete
workpiece and thus also to the transverse
machining of shaft ends
The AWG does not machine inside areas on the
rear face. If jaws are used for clamping the shaft
at the spindle, the rear face is not machined
Longitudinal machining: First the front area is
machined, then the rear area
Collision prevention – If machining operations are
not performed without collisions, you can do the
following:
Add a retraction of the tailstock, a positioning of
the steady rest, etc. to the program
Add cutting limits to the program to avoid
collisions
Suppress automatic machining in AWG submode
by assigning the do not machine attribute or by
entering the machining location in the Machining
sequence
Define an oversize=0 for the workpiece blank. As
a consequence, the front area is not machined
(e.g. shafts cut to length and centered shafts).
