Positioning and position patterns

4.4.8.1

General information

Function
After you have programmed the technology (cycle call), you must program the positions.
Several position patterns are available:
● Arbitrary positions
● Position on a line, on a grid or frame
● Position on a full or pitch circle
Several position patterns can be programmed in succession. They are traversed in the order
in which you program them.
Approach/retraction
1. The programmed positions are machined with the previously programmed tool (e.g.
2. With technological follow-up operations (e.g. centering - drilling - tapping), the respective
Tool traverse path
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.

Arbitrary positions - CYCLE802

Function
The "Arbitrary positions" cycle allows you to program positions freely, i.e. rectangular or
polar. Individual positions are approached in the order in which you program them. Press
softkey "Delete all" to delete all positions programmed in X/Y.

center drill). Machining of the positions always starts at the reference point. In the case of
a grid, machining is performed first in the direction of the 1st axis and then back and forth.
The frame and hole circle are machined counterclockwise.
drilling cycle must programmed after calling the next tool (e.g. drill) and immediately
afterwards the call of the position pattern to be machined.
