10.3 Contour turning
10.3.1 General information
Function
You can machine simple or complex contours with the "Contour turning" cycle. A contour
comprises separate contour elements, whereby at least two and up to 250 elements result in
a defined contour.
You can program chamfers, radii, undercuts or tangential transitions between the contour
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.
When you machine the contour, you can make allowance for a blank contour, which must be
entered before the finished-part contour. Then select one of the the following machining
technologies:
● Stock removal
● Grooving
● Plunge-turning
You can rough, remove residual material and finish for each of the three technologies above.
Note
Starting point or end point of the machining outside the retraction planes
For programs with contour machining from earlier software releases, for an NC start, it is
possible that one of the alarms 61281 "Starting point of machining outside retraction planes" or
61282 "End point of machining outside retraction planes" is output.
In this case, adapt the retraction planes in the program header.
Programming
For example, the programming procedure for stock removal is as follows:
Note
When programming in G code, it must be ensured that the contours are located after the end
of program identifier!
