Programming a position pattern in ShopTurn
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.

drilling cycle must programmed after calling the next tool (e.g. drill) and immediately
afterwards the call of the position pattern to be machined.
The programmed positions are machined with the previously programmed tool (e.g.
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 meandering
back and forth. The frame and hole circle are machined counterclockwise.
For G code, for lines/frames/grids, a start is always made at the next corner of the frame
or grid or the end of the row. The frame and hole circle are machined counterclockwise.
