Abstract

This study aims to analyze the mechanical properties of composite with a composition of 86% aluminum 1020, 12% fly ash and 2% magnesium, the three composite materials are combined in a furnace with the Direct Melt Oxidation method, after the melting process with a temperature of 900oC and the holding time varying 4 hours , 5 hours and 6 hours. Later, the Brinell hardness tester, at K4 the average value of BHN was 49.00816 kgf / mm, K5 the average value of BHN was 51.80066 kgf / mm and K6 the average value of BHN was 56.64983 kgf / mm. In the observation of Scaning Electron Microscope K6 specimens that have the best pores, changes in the microstructure of these composites are increasingly visible on the 5000x magnification observation. This is due to the holding time which helps the infiltration process in the interface reaction between the liquid and solid phases, and the user of this holding time is due to the metal's wetting ability and the slow and time-consuming infiltration process. to get a more even mixture.

Abstract

Surface roughness is one of the criteria for determining machining quality. This parameter is influenced by machining parameters such as cutting speed (Vc), motion feed (fz) and radial depth of cut (ar). The material is processed using side milling with down milling feeding direction. The results of the milling process are measured with a surface roughness tester by taking the roughness arithmetic (Ra) value as the roughness value. Surface roughness prediction is done using response surface methodology (RSM). RSM was chosen as a quantitative approach based on experimental and modeling data. The number of data retrieval in this study were 16 experimental data for 3 machining parameters. Surface roughness modeling of AISI 1045 milling by Quadratic response surface methodology showed significant model results. Evidenced by the F-Value of 5.61 and P-Value of 0.0241. P-Value was <0.05 means that the model is significant. The mean square error mean in this study also showed good results in the amount of 0.0091 and an average error of 0.122%. The effect of cutting speed on roughness is the higher the cutting speed will produce a smooth roughness value, while the effect of feeding motion and feeding depth on roughness is directly proportional, the higher the value of feeding motion and the depth of feeding, the coarser the roughness score will be.

Abstract

Bending and notching is a common process in manufacturing world as in vehicles chassis fabrication. But, the recent problem is the limited tools that needed to bend and notch pipes. The objective of this research is to fabricate a tool or production machine that could bend and notch pipes based on need by using three roll bending method. As for the notching angle of 0  to 60  and the diameter for notching cutting is 1 to 2 inch. There are some calculations on machine structure by using solidworks simulation such as stress analysis, von mises and factor of safety. There are three trials in bending process such as deflection from 1, 2 and 3 cm and on the other side, notching trials start from 0  to 60 . This notching and bending machine created with two functions. The bending process is conducted in the middle part while the notching process is in the top part of the machine. This machine has 70 cm length, 50 cm wide and 120 cm height and the total amount of cost spent for this machine is Rp. 9.009.500.

Abstract

Damage cutting tools on CNC machines is a common problem that is often encountered in the field of machining industry. Long tool life can certainly save the expenditure of the company because minimizing the purchase of new cutting tools because of the damage, for that this research aims to help estimate the age of cutting tools on slot cutter drill short type of carbide and HSS and get an idea of how long the cutter can be used and know the impact of the regrinding process on the cutting tools. In this study used quantitative methods where research focused on the use of data analysis software computer cutting and data service and also manually calculation results presented in the form of tables and graphs. The results obtained by carbide cutters have a longer tool life of 706 minutes compared with a cutter HSS 162 minutes to achieve a degree of stroke-0.1 mm and the regrinding process leads to the reduction of feeding speed, cutting speed and performance on the cutter.

Abstract

The research was conducted by redesigning the shell-and-tube MOES C heat exchanger by PT. Krakatau Steel, using the HTRI application to find the effectiveness value (E > 0.5). The flow type is counterflow, double segmental type baffles, two tube passes with water, oil fluid, and baffle spacing are 60 mm, 90 mm, and 100 mm, flow rate 5,716 kg/s, 5,781 kg/s, and 5,808 kg/s. The increase in flow rate on the Heat Exchanger results in a decrease in effectiveness, on the contrary, at the minimum flow rate in the Heat Exchanger there is an increase in effectiveness. The greater the number of baffles in the Heat Exchanger, the greater the value of the pressure drop, which results in a decrease in heat transfer at the Heat Exchanger. The higher the flowrate, the greater the heat transfer value, but also the greater the mass and the greater the value of pressure drop that occurs in the Heat Exchanger. The large number of baffles and flowrate also affects the pressure drop and heat transfer values.

Abstract

In terms of the truth of the power on the bike is very important because lately many people are using this folding bike. On this night, use element method until application is labor-intensive. Before the analysis of the meshing process on the frame. After that the analysis is nothing. In this analysis the voltage result is not the value of the yield strength value on the material. So it doesn't break the frame. In addition to voltage, there are also strains and reforms that occur in frames whose value is not too large frame undergoes elastic deformation, and the result of analysis of security value is at least 10.6. This is the power of matter smaller than the voltage that occurs. So it can be stated that the bike will be safe if enabled or times.
