abstract
This paper is devoted to present the most recent
results regarding the ongoing work carried out in the scope of
the STC 4.0 HP project, which aims to automate the finishing
process of ceramic tableware at the GRESTEL S.A. industry,
focusing on non-circular shaped plates. A collaborative robot is
in charge of handling the tableware and making it go around
its entire perimeter through a sponge, to perform the finishing.
An array, with the distances from the center to the different
points of the plate, is applied as data to trace the path that the
robot must follow. The final goal of this prototype is to obtain an
even finish while maintaining a constant force along the entire
perimeter of the ceramic tableware. After carrying out a series
of tests, it was possible to conclude that the current approach
was able to manipulate 3D-printed tableware made for testing
and travel its perimeter to carry out the finishing.
This work has been supported by the STC 4.0 HP (New
Generation of Stoneware Tableware in Ceramic 4.0 by High-
Pressure Casting Robot work cell) Project with reference
