Representation Of The Contour - Siemens SINUMERIK 840D sl Turning Operating Manual

1. Enter the blank contour
If, when removing stock along the contour, you want to take into account a blank contour
(and no cylinder or no allowance) as blank shape, then you must define the contour of the
blank before you define the finished-part contour. Compile the blank contour step-by-step
from various contour elements.
2. Enter finished-part contour
You build up the finished-part contour gradually from a series of different contour elements.
3. Contour call - only for G code program
4. Stock removal along the contour (roughing)
The contour is machined longitudinally, transversely or parallel to the contour.
5. Remove residual material (roughing)
When removing stock along the contour, ShopTurn automatically detects residual material
that has been left. For G code programming, when removing stock, it must first be decided
whether to machine with residual material detection - or not. A suitable tool will allow you to
remove this without having to machine the contour again.
6. Stock removal along the contour (finishing)
If you programmed a finishing allowance for roughing, the contour is machined again.

Representation of the contour

G code program
In the editor, the contour is represented in a program section using individual program blocks.
If you open an individual block, then the contour is opened.
ShopTurn program
The cycle represents a contour as a program block in the program. If you open this block, the
individual contour elements are listed symbolically and displayed in broken-line graphics.
Symbolic representation
The individual contour elements are represented by symbols adjacent to the graphics window.
They appear in the order in which they were entered.
