General information about contour definitions

Function
The contour definition programming is used for the quick input of simple contours.
Programmable are contour definitions with one, two, three or more points with the transition
elements chamfer or rounding, through specification of Cartesian coordinates and/or angles.
Arbitrary further 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 codes,
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 via the contour calculator are
transferred to the part program.

Assigning parameters
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 machine manufacturer's specifications.
