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.
Note
The number of positions that can be programmed in a "Positions" step is limited to a maximum
of 600!
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 403)").
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 programmed after calling the next tool (e.g. drill) and immediately
afterwards the call of the position pattern to be machined.
Tool traverse path
● ShopTurn
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 counter-clockwise.
● G codes
For G code, for rows/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 circle or pitch circle are machined counter-
clockwise.
Working with rotary axis
In the G code, the C axis is supported during drilling (any position pattern, full circle, and pitch
circle).
With ShopTurn, the C axis is supported by the following selection options of the machining area:
● Face C
● Peripheral surface C
