Positions And Position Patterns - Siemens SINUMERIK 828D Operating Manual

Positions and position patterns

Function
● Arbitrary positions
● Position on a line, on a grid or frame
● Position on a full or pitch circle
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 352)").
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.
