Fixed Cycles: Contour Pocket | TROCHOIDAL SLOT (Cycle 275, DIN/ISO: G275, software option 19)

Please note while programming:

The algebraic sign for the cycle parameter DEPTH
determines the working direction. If you program
DEPTH=0, the cycle will not be executed.
When using Cycle 275 TROCHOIDAL SLOT, you
can define only one contour subprogram in Cycle 14
CONTOUR.
Define the center line of the slot with all available path
functions in the contour subprogram.
The memory capacity for programming an SL cycle is
limited. You can program up to 16384 contour elements
in one SL cycle.
The TNC does not need Cycle 20 CONTOUR DATA in
conjunction with Cycle 275.
The starting point of a closed slot must not be located in
a contour corner.
Danger of collision!
If you set the parameter posAfterContPocket to
ToolAxClearanceHeight, the TNC positions the tool after the end
of the cycle only in the tool axis direction to the clearance height.
The TNC does not position the tool in the working plane.
After the end of the cycle, position the tool with all
coordinates of the working plane, e.g.
After the cycle, program the absolute position (not an
incremental traversing movement)
