Please note while programming:
The machine and TNC must be prepared for cylinder
surface interpolation by the machine tool builder. Refer to
your machine manual.
In the first NC block of the contour subprogram, always
program both cylinder surface coordinates.
The memory capacity for programming an SL cycle is
limited. You can program up to 8192 contour elements in
one SL cycle.
The algebraic sign for the cycle parameter DEPTH
determines the working direction. If you program
DEPTH=0, the cycle will not be executed.
This cycle requires a center-cut end mill (ISO 1641).
The cylinder must be set up centered on the rotary table.
The tool axis must be perpendicular to the rotary table. If
this is not the case, the TNC will generate an error
message.
This cycle can also be used in a tilted working plane.
