Abstract

As global technology and industry continue to develop rapidly, the manufacturing industry in Indonesia is also becoming increasingly advanced to keep pace with global industrial progress. A good surface metal is one that is clean from all types of contaminants such as dust, rust, oil, paint, and has a uniform surface roughness. Sandblasting is a method used to remove rust, dirt, and other impurities like oil and paint from metal surfaces. This research aims to design a sandblasting tool using Capstone Design analysis. The process includes selecting the type of sandblasting tool, determining its specifications, and calculating the dimensions of the blasting chamber. Additionally, the study involves assembling the sandblasting chamber, installing the required sandblasting components, as well as testing the functionality of the completed sandblasting system. Based on the functional testing results of the designed sandblasting tool, it can be concluded that the sandblasting tool functioned well and can be used by future researchers. From the roughness test results, it was found that the surface roughness after sandblasting is significantly higher compared to the initial condition.

Abstract

The study utilizes the Single Particle Finite Element Analysis (FEA) method with a Cowper-Symonds Strain Rate Material Model to understand the response of SKD11 tool steel to erosion under varying impact angles and velocities. In this study, SiO₂ particles measuring 0.7 mm in diameter were selected as the erodent, while the target material, SKD11, was sized at 1x1x0,5 mm. The impact angle was varied at 30, 60, and 90 degrees, and the impact velocity was set at 25 and 50 m/s. The simulation results show that SKD11 performs best at lower impact angles. It was observed that as the impact angle increases, the erosion also increases significantly, particularly at 60 degrees. Different impact angles also resulted in different erosion mechanisms on the material's surface. The impact velocity further contributed to an increase in erosion, with material failure and material reduction occurring at 50 m/s.
