 Angle for spindle orientation Q336 (absolute value): Angle at
which the TNC positions the tool before it is plunged into or
retracted from the bore hole.
Danger of collision!
Check the position of the tool tip when you program a
spindle orientation to the angle that you enter in Q336 (for
example, in the Positioning with Manual Data Input mode
of operation). Set the angle so that the tool tip is parallel to
a coordinate axis. Select a disengaging direction in which
the tool moves away from the edge of the hole.
