Look Ahead
•
Defined rounding of discontinuous contour transitions (e.g. 3D surfaces)
•
Collision viewing with the SL cycle for "open" contours
•
Advance calculation of geometry for feed-rate adjustment
Free contour In HEIDENHAIN Plain Language with graphic support
programming FK
Coordinate Shift and/or rotate coordinate system, mirroring, reduce and enlarge -
transformations also axis-specific
Tilting the – Yes 1 )
working plane
Subprogram Program section repeats, subprograms, program calls
functions
Fixed cycles Pecking, tapping, slot cutting, rectangular and circular pockets,
SL cycles (milling cycles whose contour descriptions are stored in
subprograms); the machine tool manufacturer can also integrate
customized macros
