Abstract

This study aims to analyze the effect of pressure and blasting time variations on the
surface roughness of SS400 steel during the sandblasting process. The primary
objectives are to determine the influence of spray pressure and blasting time on
surface roughness and to identify the optimal parameter settings to achieve the
desired surface characteristics. The research employs the Taguchi method to
systematically evaluate the influence of different parameter combinations and to
enhance process efficiency.
Experimental results reveal that the highest surface roughness value, 0.54 µm, was
obtained at a spray pressure of 6 bar and a blasting time of 20 seconds. In contrast,
the lowest surface roughness value, 0.24 µm, was achieved at a pressure of 5 bar
and a blasting time of 10 seconds. Statistical analysis indicates that among the two
variables tested, blasting time has the most significant effect on the resulting surface
roughness.
Furthermore, the study aims to meet an optimal surface roughness target within the
range of 30 µm to 85 µm, which is commonly required for surface preparation
standards. The combination of 6 bar pressure and 20 seconds of blasting time
produced a surface roughness value of 0.54 µm with a surface cleanliness level of
SA 3, which is considered optimal in terms of both roughness and cleanliness
criteria. These findings provide valuable insights for the selection of sandblasting
parameters, contributing to improved quality control and process optimization in
industrial surface treatment applications.
