Positioning and position patterns

Function
The positions are programmed after the technology (cycle call). Several position patterns are
available:
● Arbitrary positions
● Position on a row, on a grid or a frame
● Position on a full or pitch circle
Several position patterns can be programmed in succession. They are executed in the order
in which you program them.
Note
The number of positions that can be programmed in the one "Positions" step is limited to a
maximum of 600!
Programming a position pattern in ShopMill
Several position patterns can be programmed in succession (up to 20 technologies and
position patterns in total). They are executed in the order in which you program them.
The programmed technologies and subsequently programmed positions are automatically
linked by the control.
Displaying and hiding positions
You can display or hide any positions (Section "Displaying and hiding positions (Page 367)").
Approach/retraction
1. Within a position pattern, or while approaching the next position pattern, the tool is retracted
to the retraction plane and the new position or position pattern is then approached at rapid
traverse.
2. With subsequent technological operations (e.g. centering - drilling - tapping), the respective
drilling cycle must be programmed after calling the next tool (e.g. drill) and immediately
afterwards the call of the position pattern to be machined.
