Abstract

The aim of this study is searching a new method to provide wear rate measurement which simple and have better accuracy that occur in worn mining component surface addressed like flare chisel bucket teeth. Having correlation between Wet Sand Abrasion Test ASTM G105 and 3D scan modeling of worn surface, the validation of a new method to provide wear rate measurement using 3D scan technology would be elaborated. The preliminary study to provide wear rate measurement using 3D scan imaging have been established. The study related volume comparison by which 3d scan imaging process generated and buoyancy. Specimens were abraded using Wet Sand Abrasion Test ASTM G105 to provide specimen in certain percentage of volume loss. Several specimens consist of different percentage of volume loss were prepared. Specimens measured its volume over buoyancy and 3D scan imaging in two grade of meshing which are normal and smooth. Both of volume generated from 3D scan imaging compared to buoyancy volume measurement.  Study focused on dissimilarity among volume data generated. Analysis are carried out through the center and variability both 3D scan volume compared to buoyancy volume. The study shows that normal meshing has less dissimilarity level compare to smooth meshing. Both dissimilarity level span at -0.01% and -0.027% respectively. Higher mesh level tends to inaccurate volume measurement. Further study to determine suitable mesh level should be conduct in near future.

Abstract

The WHO report states 372,441 people die every year due to drowning. The curative effort to overcome drowning is by means of a float. Nearly drowning victims need speed of handling. Therefore, the development of the buoy is directed at increasing the velocity of the motion of the buoy. The purpose of this research is to find a relationship between the geometry of the buoy section with the optimum speed of motion. The completion methodology in this final project is literature study, problem identification (buoy volume calculation), buoy design and design parameters, buoy sensitivity study to 100 kg payload, checking ergonomic limits, computational fluid dynamics studies (CFD) and checking fluid flow velocity in buoys. . The result is the fluid flow velocity targeted at five cross-sectional shapes (rectangle, circle, ellipse, bullet, and comparator), namely 2.8 m / s has not been achieved. By all the step done, we concluded that each section has an unique characteristic. Some of them were recommended to study in next research.

Abstract

The seal face is the main component of a mechanical seal to prevent leakage in a system with fluid flow. Seal face manufacture is generally produced by the material removal process, which causes some raw material waste. Powder metallurgy is the process of manufacturing products from metal powders with raw material efficiency of up to 97%. This study discusses the relationship between the manufacturing process parameters of seal face with SiC material through a powder metallurgy process as a substitute for manufacturing by material removal. The approach used in this research was the design of experiments with the Taguchi method and the technique of Gray Relational Analysis. Process parameters controlled were compaction pressure (CF), compaction time (CH), sintering temperature (ST), and sintering time (SH). Responses were measured in the form of surface hardness (HV) and density. The combination of process parameters that produces the optimum response is CF = 408 N/mm2 (level 3), CH = 2 min (level 1) ST = 1050°C (level 3), SH = 120 min (level 2) with contribution of process parameters CF = 38.06%, CH = 2.53%, ST = 49.50%, and SH = 9.91%. The optimum surface hardness and density values were 513.03 HV and 3.04 gr/mm3.
