4.9 Drilling/Milling Patterns

Note on using drilling/milling patterns:

 Drilling patterns: MANUALplus generates the machine commands

M12, M13 (apply/release block brake) under the following

conditions: the drill/tap must be entered as driven tool (parameter

"Driven tool H") and the "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 “ICP

Example "Milling Cycle"” on page 507).
