Thanks to the method proposed the part quality was
significantly enhanced with respect to the manual
machining: the measured value of the planarity was
between 0.3mm and 0.8mm. Compared to the manual
process, the robot machining was a slower process,
taking 10 minutes instead of 8 minutes, but the final
quality was greater and more constant. Moreover, thanks
to the OLP approach, the workcell reconfiguration at the
batch change required only the 20% of the time needed to
manually teach a new robot program of complex
workpieces.
