10.3 Contour milling
10.3.1 General
Function
You can mill simple or complex contours with the "Contour milling" cycle. You can define open
contours or closed contours (pockets, islands, spigots).
A contour comprises separate contour elements, whereby at least two and up to 250 elements
result in a defined contour. Radii, chamfers and tangential transitions are available as contour
transition elements.
The integrated contour calculator calculates the intersection points of the individual contour
elements taking into account the geometrical relationships, which allows you to enter
incompletely dimensioned elements.
With contour milling, you must always program the geometry of the contour before you program
the technology.
10.3.2 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.
ShopMill 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.
