8 Cycles<br />

8.3 SL Cycles<br />

8-28<br />

Example: Overlapping pockets with islands<br />

Inside machining with pilot drilling, roughing out<br />

and finishing.<br />

PGM S829I is based on S824I:<br />

The main program has been expanded by the<br />

cycle definitions and cycle calls for pilot drilling<br />

and finishing.<br />

The contour subprograms 1 to 4 are identical to<br />

those in PGM S824I (see page 8-24) and are<br />

added after block N300.<br />
