Example: Interpolation Turning Cycle 291

Cycle 291 COUPLG.TURNG.INTERP. is used in the
following program. This programming example illus-
trates the machining of an axial recess and a radial
recess.
Program sequence
Turning tool as defined in toolturn.trn: tool No 10:
TO:1, ORI:0, TYPE:ROUGH, tool for axial recesses
Turning tool as defined in toolturn.trn: tool No 11:
TO:8, ORI:0, TYPE:ROUGH, tool for radial recesses
Program run
Tool call: tool for axial recess
Start of interpolation turning: Description and call of
Cycle 291; Q560=1
End of interpolation turning: Description and call of
Cycle 291; Q560=0
Tool call: Recessing tool for radial recess
Start of interpolation turning: Description and call of
Cycle 291; Q560=1
End of interpolation turning: Description and call of
Cycle 291; Q560=0
By converting parameter Q561, the
turning tool is displayed in the simulation
graphic as a milling tool.
