Contour Definitions: One Straight Line - Siemens SINUMERIK 840D sl Programming Manual

Fundamentals
2.9 Motion commands
Additional arbitrary NC addresses can be used, e.g. address letters for further axes (single
axes or axis perpendicular to the machining plane), auxiliary function specifications, G
commands, velocities, etc. in the blocks that describe contour definitions.
Note
Contour calculator
The contour definitions can be programmed easily with the aid of the contour calculator. This
is a user interface tool that enables the programming and graphic display of simple and
complex workpiece contours. The contours programmed using the contour calculator are
transferred to the part program.

Parameterizing
The identifiers for angle, radius and chamfer are defined via machine data:
MD10652 $MN_CONTOUR_DEF_ANGLE_NAME (name of the angle for contour definitions)
MD10654 $MN_RADIUS_NAME (name of the radius for contour definitions)
MD10656 $MN_CHAMFER_NAME (name of the chamfer for contour definitions)
Note
See the machine manufacturer's specifications.
2.9.9.2

Contour definitions: One straight line

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 straight line is defined by the following specifications:
● Angle ANG
● One Cartesian end point coordinate (X2 or Z2)
