Abstract

Welding is one of the metal joining processes in manufacturing. CDFW (continuous drive friction welding) is a welding process to join two workpieces by applying pressure at one end of the object and rotating another one where the friction action applies at interface. The purpose of this study is to study temperature distribution on the surface of the welding area and the heat-affected zone represented by a fully plasticized zone (Zpl) and to get an insight of a friction welding process. The variables of CDFW used were double chamfer angle, upset pressure, and burn off  length. The initial area of friction was equal that is at a diameter of 14 mm. The method of modeling the CDFW friction welding is via computer simulations using ANSYS 18.1 software. This research uses aluminum material type Al6061. The Taguchi method was applied in designing the simulations. In this modeling, the model with the double chamfer of 15 °, the upset pressure of 120 MPa, and the burn-off length of 9 mm has a small ZPl area of 10.256 mm2. Whilst the specimen model, with a double chamfer angle of 45 °, the upset pressure of 240 MPa,   and the burn-off length of 7 mm has a large Zpl area of 56.55mm2. The area of a narrow fully plasticized area caused by small chamfer angle and an upset pressure of 240 MPa. The area of fully plasticized zone shows how much material can be integrated during the friction welding process and how much strength of the weld metal. The model with the chamfer angle of 15 º,   the upset pressure of 240 MPa, and the burn-off length of 9 mm has the widest temperature distribution and the highest maximum temperature. Meanwhile, the model with the chamfer angle of 30º, the upset pressure of 120 MPa, and the burn-off length of 9 mm has the narrowest temperature distribution and the lowest maximum temperature. The smaller chamfer angle increased upset pressure and burn-off length result in the wider temperature distribution, higher maximum temperature, and smaller Zpl.

Abstract

 Crash box serves as a kinetic energy absorber during collision. It has a tube shape, which is located between bumper and chasis. The crash box design requires development in order to reduce buckling mode and obtain symmetry folding mechanism, so it will achieve greater energy absortion. The researchers find a method to reduce tension due to impact by providing dents in crash box geometry. This research observed origami pattern crash box design having dents functioned as pre-folded so that collapse mode can be predicted and stable. In this research, the crash box was modeled according to the size of bumper and chassis on the MPV car. Testing simulation was performed by modelling Impactor as rigid body and crash box as flexible. Fixed support was housted in the surface of rear side of the crash box. Simulation process was started from the impactor moving to supress crash box. This Impactor collision led to deformation on the crash box. Crash box material was AA7004-T7, it was modelled as bilinier isotropic hardening. Based on the research result, the addition of pre folded pattern is able to reduce impact force at the first impact and has stable characteristic as well as predictable collapse mode.

Abstract

Metal casting with investment casting method is metal casting which has the ability to produce accurate parts and has a controlled fineness. Current technological developments are very influential in the development of investment casting. One of them has been found mold-lay filament as a substitute for wax, which is now wax is one of the main components in investment casting process. Mold-lay filament is printed using a 3D Printer machine. In this study, the wax in the investment casting process was replaced by a mold-lay filament with the specifications 0.75kg / 0.55 lb of 1.75mm MOLDLAY filament, prints at temperatures of 170-180° C. The result show that mold-lay flutes are also able to come out well from slurry molds, but require more time than wax, this is because one of the plastic mold-lay compositions, which takes a long time for the moldlay fillment to come out of the mold. Further research suggestions are needed further testing in terms of roughness of the product with moldlay filament and compared with wax. This will also see if there are any remaining moldlay filaments from the mold.

Abstract

ABSTRACTEffect of friction time, upset force and one-side cone geometry on torsion strength of A6061 round bar friction weld joint was studied. Round bar commercial A6061 was friction welded with initial compression force of 2.5 kN on stationary part and the rotated part had revolution speed of 1600 rpm with variation of friction time of 45, 50 and 55 minutes. In the upset stage, the variation of upset force of 5 kN, 7.5 kN and 10 kN with the same upset holding time of 110 seconds. The stationary part of the specimen had friction area with variation of cone geometry that represented with ratio of upper diameter, D1 and lower diameter, D2, D1/D2. It was found friction time and the ratio of D1/D2 affected torsion strength in the upset force below 10 kN. In case of the higher upset force of 10 kN, the upset force more dominant to affect torsion strength of the continuous drive friction weld (CDFW) joint. The specimen with maximum torsion strength has more precipitates in grains of microstructures compared to that of specimen with lower torsion strength. Keywords: Continuous drive friction welding, aluminum, friction time, upset force, one-sdie cone geometry, torsion strength.

Abstract

An effort to increase the tensile strength of dissimilar friction weld joint of round bar A6061/S15C was done in this study using upset force and one-side chamfer angle. Commercial round bar aluminum alloy A6061 and carbon steel S15C were used as rotated and a stationary part, respectively in continuous drive friction welding (CDFW) process. Upset force variations of 10.5, 14, and 17.5 kN were used. CDFW process used burn of length of 15 mm for all CDFW specimens. Chamfer angle was machined on friction area of the S15C stationary part with the variation of 0 (without chamfer angle), 30 and 45 degrees. Tensile strength test, macrostructure observation and micro Vickers hardness testing, SEM-EDX analysis were performed. It was found that the smaller chamfer angle (30 degrees) produced maximum tensile strength of A6061/S15C CDFW joint. It occurred due to smaller formed flash, the lower temperature of the flash that indicate lower heat input and caused smaller heat affected zone and higher hardness in the CDFW joint. The higher upset force also yields higher tensile strength of CDFW joint due to the higher degree of plastic deformation during the upset stage of CDFW joint and this state contributes to higher hardness and tensile strength of A6061/S15C CDFW joint. SEM-EDX analysis result also confirmed that more aluminum existed on the fracture surface of the A6061/S15C CDFW specimen with maximum tensile strength.

Abstract

Motorcycle users in 2019 reached 133,617,012 units in Indonesia. The impact of a large number of motorcycle certainly attracts the interest of the industry to produce two-wheeled automotive vehicles. The piston is part of the engine that functions as a compression barrier in the combustion chamber, the piston material is aluminum alloy. Therefore, research was carried out on making pistons with investment casting methods, physical and mechanical patterns from 3D printers on pistons. This research starts from drawing the piston using CAD (computer-aided design), making a printed pattern from a 3D Printer machine with PLA (polylactide acid) material. The mold pattern is coated with a mixture of gypsum cement and silica powder. The casting process with a pouring temperature of 750ᵒC and a mold temperature of 200 ᵒC, 250 ᵒC, 300 ᵒC, 350 ᵒC, and 400 ᵒC. The results showed the largest grain size at a mold temperature of 400ᵒC. The highest hardness at 200 ᵒC mold temperature is 47.00 HRB and the lowest hardness at 400 ᵒC mold temperature is 40.56 HRB. The higher the temperature of the mold used, the level of porosity of a material will decrease. This is due to the temperature difference when pouring the molten metal and the lower mold temperature. This makes the metal solidification time longer. The higher the mold temperature, the slower the solidification time, the larger the grain structure, and the decreased hardness.

Abstract

The manufacturing industry mostly uses CNC Milling machines in processing products that require high precision values. This machine is capable of a wide variety of feeding methods, inclinations, feed speeds, various tool styles, and much more. The purpose of this research is to analyze one method of infeed direction with the Zig-Zag effect by using 2 types of normal and variable tool types combined with variations in spindle speed and DOC to find out which variable is effective and produce a smoother comparison of surface roughness values. The type of material tested was SS 304 because this material has good advantages against corrosion. From the results of research conducted on this material for the use of a variable tool, it has an average roughness value of 0.327 µm and for the results of the roughness test on the use of a normal tool, it has an average roughness value of 0.470 µm. From the results of this research, it can be concluded that the value of the Depth Of Cut (DOC), the roughness value are directly proportional, and the faster the spindle rotation, the frictional force generated also increases. The highest Ra value from the research results occurred in DOC 1.6 mm with a spindle speed of 2750 rpm using a variable tool of 0.361 µm and a roughness value of 0.516 µm on a normal tool. The conclusion of this research is that the variable tool produces a lower Ra value than the normal tool so that the type of material defects caused by chatter vibration can be reduced.
