4.9 Drilling and milling patterns
Note on using drilling/milling patterns:
 Drilling patterns: The MANUALplus generates the
machine commands M12, M13 (apply/release block
brake) under the following conditions: the drill/tap must
be entered as driven tool (parameters driven tool AW
and direction of rotation MD must be defined).
 ICP milling contours: If the contour starting point is
outside the coordinate datum, the distance between
contour starting point and coordinate datum is added to
the pattern position (see "Examples of pattern
machining" on page 353).
