Contour Pocket/Contour Spigot (Cycle63/64) - Siemens SINUMERIK 840D sl Operating Manual

Parameter Description
Retraction strat‐ ● Axis by axis
egy
● Spatial (not with perpendicular approach mode)
R2 Retraction radius - (only for "quadrant or semi-circle" retraction)
L2 Retraction distance - (only for "straight line" retraction)
Lift mode If more than one depth infeed is necessary, specify the retraction height to which the tool
retracts between the individual infeeds (at the transition from the end of the contour to
the start).
Lift mode before new infeed
● Z0 + safety clearance
● By the safety clearance
● to RP
● No retraction
FZ Depth infeed rate – (only for axis-by-axis approach strategy)
(only for ShopMill)
FZ - (only for G Depth infeed rate – (only for axis-by-axis approach strategy)
code)
FS Chamfer width for chamfering - (only for chamfering machining)
ZFS Insertion depth of tool tip (abs or inc) - (for machining only)
* Unit of feedrate as programmed before the cycle call
Note
Cylinder surface transformation with slot side compensation
For cylinder surface transformation with selected slot side compensation and approach/
retraction in quadrant or semi-circle, the approach/retraction radius must be greater than
"Offset to programmed path – tool radius".

Contour pocket/contour spigot (CYCLE63/64)

Contours for pockets or islands
Contours for pockets or islands must be closed, i.e. the starting point and end point of the
contour are identical. You can also mill pockets that contain one or more islands. The islands
can also be located partially outside the pocket or overlap each other. The first contour you
specify is interpreted as the pocket contour and all the others as islands.
Automatic calculation / manual input of the starting point
Using "Automatic starting point" you have the option of calculating the optimum plunge point.
By selecting "Manual starting point", you define the plunge point in the parameter screen.
