Abstract(s)
The work described in this paper address the
problems of productivity of Grohe's Portugal grinding/
polishing department, related to the frequent stops of robotic
cells for on-line programming and program adjustments. The
solution to the stated problem was achieved through the
adoption of off-line programming as an alternative to the
conventional on-line method. Efforts were developed to
overcome some limitations and restrictions found in terms of
the software applications used, in order to adapt and improve
their use to the needs of this type of contact applications. The
solution developed is currently used for off-line programming
the grinding robots at Grohe Portugal, with a significant
reduction in the cells stop time to program the robots and also
in the cycle time. The application of the off-line programming
method and of the new programming techniques allowed to
obtain a reduction of the cell stop time (up to 85% reduction),
to optimize the production cycle time (up to 10% reduction)
and, simultaneously, good results in terms of product finishing.
The main limitations faced are the lack of realism of the wheel
flexibility and the lack of sensitivity of the contact force with it.
