Creating contour elements
After you have created a new contour and specified the starting point, you can define the
individual elements that make up the contour.
The following contour elements are available for the definition of a contour:
● Straight vertical line
● Straight horizontal line
● Diagonal line
● Circle/arc
● Pole
For each contour element, you must parameterize a separate parameter screen.
The coordinates for a horizontal or vertical line are entered in Cartesian format; however, for
the contour elements Diagonal line and Circle/arc you can choose between Cartesian and
polar coordinates. If you wish to enter polar coordinates you must first define a pole. If you
have already defined a pole for the starting point, you can also refer the polar coordinates to
this pole. Therefore, in this case, you do not have to define an additional pole.
Cylinder surface transformation
For contours (e.g. slots) on cylinders, lengths are frequently specified in the form of angles. If
the "Cylinder surface transformation" function is activated, you can also define on a cylinder
the length of contours (in the circumferential direction of the cylinder surface) using angles.
This means instead of X, Y and I, J, you enter Xα, Yα and Iα, Jα.
Please refer to the machine manufacturer's specificati
ons.
Parameter entry is supported by various help screens that explain the parameters.
If you leave certain fields blank, the geometry processor assumes that the values are
unknown and attempts to calculate them from other parameters.
Conflicts may result if you enter more parameters than are absolutely necessary for a
contour. In such a case, try to enter fewer parameters and allow the geometry processor to
calculate as many parameters as possible.
