8.6 SL Cy
cles
Before programming, note the following:
The memory capacity for programming an SL cycle is
limited. For example, you can program up to 1024 straight-
line blocks 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.
The TNC checks whether the compensated and non-
compensated tool paths lie within the display range of the
rotary axis, which is defined in machine parameter 810.x.
If the error message “Contour programming error” is
output, set MP 810.x = 0.
