Contour definitions: Three straight line (ANG)

Note
In the following description it is assumed that:
• G18 is active (⇒ active working plane is the Z/X plane).
• The following identifiers have been defined for angle, radius and chamfer:
Function
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.
Note
The programming described here for a three point contour definition can be expanded
arbitrarily for contour definitions with more than three points.

(However, the programming of contour definitions is also possible without restrictions with
G17 or G19.)
– ANG (angle)
– RND (radius)
– CHR (chamfer)
