Function
The free contour programming is a support tool for the editor.
The contour programming function enables you to create simple or
complex contours.
An integrated contour calculator calculates any missing parameters
for you, provided that they can be computed from other parameters.
A contour comprises separate contour elements, whereby at least two
and up to 250 elements result in a defined contour. You can also
program undercut, radii, chamfer or tangential transitions between the
contour elements.
The programmed contours are transferred to the edited part program.
The following contour elements are available for the definition of a
contour:
Vertical line
Straight line (planar, longitudinal, inclined) horizontal
Diagonal line
Arc/circle
Further information
1. The valid geometry axes in the first channel are determined and
used in the part program.
2. The contour elements of the contour chain are displayed by
symbols or text. The mode of representation can be set via the
"Setting contour" function in the editor.
