Abstract

In the current development of the manufacturing industry, the quality of each product must be met. One machining process, namely CNC lathe, can meet these demands. Surface roughness is one of the values that must be considered again. The minimum surface roughness indicates a very good CNC machining process, because the smaller the surface roughness value of a product, the better the resulting product value. To achieve that all need to du the turning in the right process variables. The process variables that are varied are cutting speed (m/mnt) and depth of cut (mm). Each variable has three levels, mnamely cutting speed 240, 250, and 260. For depth 0,1, 0,15, and 0,2. The research method used to obtain surface roughness values is the response surface methodology (RSM) with a central composite design. The material used in this research is SKD 11 steel. The minimum roughnees is at acutting speed of 240 m/min and a depth of cut of 0,325 mm, the roughness value abtained is an average of 1,627 (µm). for maximum roughness at a cutting speed of 230 m/min and depth of cut of 0,225 mm, the roughness value obtained of 1,975 (µm).

Abstract

In the current era, the automotive industry is growing rapidly, one of which is in the field of transportation in the manufacture of brake linings. Generally, brake linings are made of materials containing asbestos which endanger health. Therefore, a material innovation is needed to replace the role of asbestos such as aluminum matrix composites. The purpose of this study was to determine the effect of different hot compaction pressures on the density and hardness of AMC reinforced with SiC and RHA. The method used in this research is powder metallurgy method, which consists of preparation, mechanical mixing, compacting, and sintering stages. The mixing process uses a ball mill machine with ball ratio parameters of 10:1 and stirring time for 2 hours and with a rotating speed of 90 rpm. The compacting process is done by two-way pressing from a hydraulic press machine with a pressure gauge. In this process the parameters used are 5600 PSi, 6000 Psi and 6400 Psi pressure with a holding time of 15 minutes. Density testing was done with ASTM B962-17 according to Archimedes' law. Hardness testing using ASTM E110-14 with a portable brinell hardness tester. The test results show that the higher the compaction pressure, the higher the density and hardness values. With the highest density value of 1.69 g/mm3 and the highest hardness value of 39.33 HB for specimens with 6400 Psi compaction pressure parameters.

Abstract

In the world of manufacturing technology there is the latest breakthrough called 3D Printing which is based on layer manufacturing. In making products, a method of adding material in layers is used, usually called additive manufacturing. The principle used in this manufacturing process technology is layered modeling, by converting 3D data directly from computer-aided design (CAD) into a physical model. Many manufacturing technologies have been developed to make prototypes according to needs, for example FDM (Fused Deposition Modeling). Setting factors and experimental levels is an important step in maximizing the quality of research level products referring to transparent materials formed from polypropylene filaments. The factors that vary are Nozzle Temperature, Bed Temperature, Print Speed, and Layer Height. This research design uses the Taguchi method. This research uses an L9 orthogonal matrix with 3 levels. Based on the results of the research carried out, we can conclude that in the impact strength test there is an increase in the results of the impact strength test with the most influential process parameters, respectively, namely Print Speed (35mm/s), Layer Height (0.3mm), Bed Temperature (97 °C) and Nozzle Temperature (215°C) using Polypropylene filament. So the strongest impact strength test value is in experiment no. 2 with an average value of 0.03370 Joules and the weakest is in experiment no. 1 with an average value of 0.02959 Joules.

Abstract

In general, brake linings are made using asbestos materials, but brake linings made from asbestos are very dangerous for health. Therefore, it is necessary to develop innovative environmentally friendly materials, one of which is aluminum matrix composite. This research process aims to determine the effect of differences in hot compaction pressure and sintering temperature on the density and hardness properties of recycled aluminium matrix composites reinforced with alumina and bagasse ash. The method used to make composites from aluminum is the powder metallurgy method, which includes preparation processes, powder mixing, compaction, and sintering. Mixing aluminium, alumina powder, and bagasse ash using a horizontal ball mill machine and using process parameters which include Ball Powder Weight Ratio (BPR) parameters of 10:1, the machine rotation speed of 90 rpm, and grinding time of 2 hours. Meanwhile, the hot compaction process uses a two-way pressing method with a hydraulic pump machine that has a pressure reader. The hot compaction process is carried out with a temperature of 500℃ held for 15 minutes and variations in the two-way compaction pressure used namely 5800 Psi, 6000 Psi, and 6400 Psi. Density testing was carried out by referring to Archimedes’ law with the ASTM B962-17 standard. This test resulted in good results at a pressure variation of 6400 Psi. Meanwhile, for hardness testing, the portable Brinell hardness test was used and referred to ASTM E110-14. In this test, the results were good at a pressure variation of 6400 Psi.

Abstract

Baggase Ash waste in Indonesia is very abundant, so that in 2021 Indonesia exported 120 metric tons of bagasse to Yokohama, Japan. This study aims to determine the effect of volume fraction and sintering temperature on density and hardness of Aluminum (Al) Matrix Composite reinforced with Alumina (Al2O3) and Baggase Ash using powder metallurgy method. The mixing process of the composite material powders used a ball mill machine with ball ratio parameters of 10:1 and stirring time for 2 hours at a rotating speed of 90 rpm. The parameters set are mechanical fusion for 2 hours, a compaction pressure of 6000 Psi, a sintering temperature varied by three kinds of 550 °C, 580 °C, 610 °C with a holding time duration of 15 minutes, and with three kinds of aluminum matrix fractions, namely 95%, 90%, 85% with alumina alloy reinforcement and baggase ash is 5%, 10%, 15%. Density testing was carried out based on Archimedes' law with reference to the ASTM B962-17 standard, while the hardness test was based on the Brinell portable hardness test with ASTM E110-14 standard. The largest density number is obtained at 5% reinforcement content, that is 2,228 g/cm3 and the largest hardness number is obtained in the 5% sample, that is 41.6 HB.
