Example finishing
subprogram: FINISH_04
The subprogram contains the NC blocks for the geometry and all the data required for produc-
tion. Assuming that your post processor has been optimized, all this data should be listed in the
subprogram. All subprograms are structured in a similar fashion. They only differ in terms of the
tool data, technology data, CYCLE832 parameters, and of course the NC blocks.

Pre-positioning of the tool in relation to the workpiece. In
each subprogram, a fixed position should first be
approached/swiveled into so that there is a defined orig-
inal position at the start of machining. This means that if
TRAORI is active, the way the workpiece is approached
may vary under certain circumstances. Pre-positioning
without TRAORI.
