Slot shape recognition (option)

If tool radius correction is active and collision monitoring (Page 76) is switched on, a
programmed slot with a width smaller than the tool diameter is detected as a possible contour
violation and it is omitted from machining. In certain technology-dependent application cases
(e.g. manufacturing deflection lines with a laser cutting machine), however, it is necessary to
machine the slots when the radius of the tool (laser beam) is somewhat larger than the
programmed width of the slot would allow. To give the user this option, the tool radius correction
has been expanded to include the function "slot shape recognition".
Note
The "slot shape recognition" function is an option for SINUMERIK 840D sl that requires a
license.
Article number: 6FC5800-0AS18-0YB0
Function
If the "slot shape recognition" function is active, slots that have a predefined shape are
automatically identified and their machining is ensured.
The following are detected:
● I-slot
● T-slot
If the slot width is greater than or equal to the tool diameter, the slot will be traversed as
programmed. If the slot width is smaller than the tool diameter, the equidistant path is calculated
in such a way that the tool traverses along the center of the programmed slot:
