R2 Retraction radius - (only for "quadrant or semi-circle" retraction) mm
L2 Retraction distance - (only for "straight line" retraction) mm
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).

10.5.8 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.
If the islands and the miller diameter, which must be plunged at various locations, are obtained 
from the pocket contour, then the manual entry only defines the first plunge point; the remaining 
plunge points are automatically calculated.
Contours for spigots
Contours for spigots must be closed, i.e. the starting point and end point of the contour are 
identical. You can define multiple spigots that can also overlap. The first contour specified is 
interpreted as a blank contour and all others as spigots.
