8.3.4  Creating contour elements 
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 
For each contour element, you must parameterize a separate parameter screen. Parameter 
entry is supported by various help screens that explain the parameters. 
If you leave certain fields blank, the cycle 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 entering less parameters and allowing the cycle to calculate as 
many parameters as possible. 
Contour transition elements 
As transition element between two contour elements, you can select a radius or a chamfer 
or, in the case of linear contour elements, an undercut. The transition element is always 
attached at the end of a contour element. The contour transition element is selected in the 
parameter screen of the respective contour element. 
You can use a contour transition element whenever there is an intersection between two 
successive elements which can be calculated from the input values. Otherwise you must use 
the straight/circle contour elements. 
Additional commands 
You can enter additional commands in the form of G code for each contour element. You 
can enter the additional commands (max. 40 characters) in the extended parameter screens 
("All parameters" softkey). 
You can program feedrates and M commands, for example, using additional G code 
commands. However, make sure that the additional commands do not collide with the 
generated G code of the contour. Therefore, do not use any G code commands of group 1 
(G0, G1, G2, G3), no coordinates in the plane and no G code commands that have to be 
programmed in a separate block.
