Sammanfattning
Polished concrete floors are becoming increasingly common in industrial premises
and in homes. Grinding is a method to achieve a durable, sustainable and consistently
smooth flooring solution. However, the process is time-consuming and demanding
for the operator, who is exposed to noise, vibrations, and dust for extended
periods of time. An autonomous concrete grinder would eliminate the operator from
this demanding environment and moreover reduce the cost of the method. Husqvarna
Construction manufactures machinery and tools for professional users and is
a leader in diamond tools for grinding, cutting, and drilling. They intend to develop
the field of floor grinding with the concept of an autonomous floor grinder,
something which does not currently exist on the market. This thesis project aims at
finding a solution for dust and particle management during the grinding of concrete
floors using an autonomous floor grinder.
The work was initiated with interviews and an investigation of existing products on
the market to gain a good understanding of and insight into the problem. Subsequently,
multiple ideas for solutions were generated, and then progressively inferior
alternatives were eliminated until only one concept remained. It was evaluated using
3D models and a 3D-printed prototype, along with existing testing equipment and
a prototype machine.
The results of the concept testing were compared to a similar previous measurement
conducted by the Dust and Slurry division at Husqvarna Construction, as an objective
reference value is lacking. In this comparison, it was revealed that the levels
of dust particles were higher for the developed concept compared to the product
Husqvarna used during the test. However, the concept is considered a well-founded
solution after further development.
