Contour definitions: Three straight lines

Note
In the following description it is assumed that:
● G18 is active (⇒ active working plane is the Z/X plane).
(However, the programming of contour definitions is also possible without restrictions with
G17 or G19.)
● The following identifiers have been defined for angle, radius and chamfer:
– ANG (angle)
– RND (radius)
– CHR (chamfer)
The end point of the first straight line can be programmed by specifying the Cartesian
coordinates or by specifying the angle of the two straight lines. The end point of the second and
third straight lines must always be programmed with Cartesian coordinates. The intersection of
the straight lines can be designed as a corner, a curve, or a chamfer.
