Abstract

Sebuah alat kendali semprotan cutting fluid pada minimum quantity lubrication (MQL) telah berhasil dibuat. Alat yang bekerja dengan sistem Arduino ini dihubungkan dengan sensor suhu yang diletakkan pada sisi pahat dan berhasil mengendalikan kapan cutting fluid harus disemprotkan dan kapan harus berhenti. Tujuan dari penelitian ini adalah untuk mempelajari efek penggunaan alat kendali ini terhadap kekasaran permukaan pada pembubutan baja AISI 4340. Metode Taguchi L9 digunakan untuk menyusun desain eksperimen dengan variasi parameter: metode pemberian cutting fluid, kedalaman permukaan dan komposisi campuran cutting fluid. Pahat sisipan berbahan karbida digunakan untuk memesin lurus dan roughness tester digunakan untuk mengukur kekesaran permukaan hasil pembubutan. Analisis S/N ratio dilanjutkan dengan analisis varians (ANAVA) membuktikan bahwa metode MQL yang dilengkapi sistem kendali ini mampu menghasilkan rata-rata permukaan paling halus dibandingkan metode lain. Nilai kekasaran optimum sebesar 1,941 µm diperoleh pada kombinasi permesinan dengan MQL dengan sistem kendali, depth of cut 2,0 mm, dan komposisi air terhadap minyak pada cutting fluid 7:3Effect of Minimum Quantity Lubrication (MQL) Method on Surface RoughnessA device to control the spraying of cutting fluid in minimum quantity lubrication (MQL) has been initiated. This device was programmed with Ardunio and connected to a thermal sensor which is stick on the flank face of the tool. It succeeded in controlling when the cutting fluid should be sprayed and stopped. This research aim is to investigate the effect of using this device to the machined surface roughness. The Taguchi method L9 was used for designing the experiments. Variations were made on the method of applying cutting flood, depth of cut, and cutting fluid composition. Carbide insert tools were used and roughness tester was employed to measure the machined surface roughness. Analysis of S/N ratio following with analysis of variance (ANOVA) revealed that the controlled MQL cooling application results in the minimum surface roughness. The optimum surface roughness would be achieved when using MQL with temperature controller, depth of cut of 2.0 mm, and composition between water and oil for cutting fluid of 7:3.

Abstract

This study aims to observe the tool deterioration following application of minimum quantity lubrication method (MQL). The designed MQL system is completed with an Arduino controller system which was able to be either manually-controlled or automatically-controlled. The tool used in this study is DCMT 11 insert type. The Taguchi method using the Orthogonal Array L9 design was used to compile the design of experiments with variations in depth of cut, coolant composition, and cooling fluid application methods. Each variable consists of three levels. Tool deterioration evaluated by observing it under an optic microscope from three sides of the tool. There are four levels of tool deterioration. The value of tool deterioration of each tool is the accumulation of each side view. ANOVA analysis found that depth of cut, cutting tool composition and method of applying coolant influence tool deterioration in percentage by 32.69%, 17.30 % and 12.82% respectively. Moreover, the minimum tool deterioration would be achieved when using the parameter combination of depth of cut of 1.6 mm; mixture composition of 3:7; and using the temperature-controlled MQL.

Abstract

The cutting force that reacts to cutting tool and workpieces will result deflection. Deflection is the cause of product deviation and vibration sources that can shorten the life of the cutting tool. Simulation of machining process is carried out to get an estimate of cutting force in some machining process conditions., then compare it to the experiments. The research aims to find out the influence of spindle rotary speed, feed rate and depth of cut on cutting forces in turning process with cutting tool HSS and workpiece Al 6061. This research uses three-dimensional simulation method using Third Wave AdvantEdge software. Following by comparison between the simulation with the experiments results. The simulation was in accordance to the experiments in term of the magnitude of the forces, from the biggest they are tangential, axial, and radial force respectively. Cutting force will decrease with increased spindle turning speed. Cutting force will increase with the rising feed rate and depth of cut. However, the simalution still highly deviate from the experiments at the rate of 71%, 44.3%, and 21.3% for axial, radial and tangential forces respectively. The possible cause of these high errors relates to forces measuring method in experiments.

Abstract

Fish Car Unej (FCU) Mudskip is a car designed with a rural terrain system, especially for fishing transportation. FCU Mudskip uses leaf spring suspension at the rear to support the weight of the vehicle, that is leaning towards the rear. The load of the vehicle is inclined to the rear due to the car carrying system in the form of fish and water. This conveying system can cause leaf spring failure. Therefore, this study aims to determine the value of stress, strain and cycle on leaf springs. Ansys 18.1 software was used to obtain stress, strain, and leaf spring cycle values with a thickness of 7 mm, 10 mm, and 13 mm. The value of stress on leaf springs with thickness 7 is 124,31 x 106 N/m2; thickness 10 mm is 74,92 x 106 N/m2; thickness 13 mm is 48,08 x 106N/m2; the value of strain on leaf springs with a thickness of 7 mm is 0,00075; a thickness of 10 mm is 0,00045; a thickness of 13 mm is 0,00029; Acceptable cycles of leaf springs are 7 mm thick is 69206 cycles, 10 mm is 77833 cycles, and 13 mm thick is 93054 cycles. Leaf springs with a thickness of 13 mm are the most optimal leaf springs because they can receive the most cycles of 93054 cycles, according to the function of leaf springs as vibration dampers.

Abstract

The cutting fluid is one of the essential factors in machining to increase machinability. The issuance of ISO 14000 about reducing the use of cutting fluid for its danger for operator and environment has encouraged many researchers to find ways to minimize its use. The Minimum Quantity Lubrication (MQL) is an answer to it. To further reduce the use of cutting fluid, a device that complies with MQL criteria for controlling the spray based on the tool temperature has successfully designed. This paper is discussing the effect of applying this device to the chips formation. The experiments were on turning of AISI 4340 using carbide tools. The Taguchi method L9 used to design the experiments. The variations made on the method of applying the cutting fluid, depth of cut, and cutting fluid composition. The chips formation was calculated based on the value of the degree of serration. Analysis of the S/N ratio, followed by ANOVA, revealed that the cutting fluids application method is the least factor affecting the chips formation. In contrast, the depth of cut influences the chips formation by 75 per cent more. The highest degree of serration achieved when applying the combination of depth of cut of 1.8 mm, the composition of 5:5, and flood method of applying cutting fluid.

Abstract

The car chassis as a skeleton supports all loads and is the most important component. Car chassis requirements must be rigid, twisting resistant, vibration resistant and resistant to fatigue. This study aims to find the cause of the failure of the Titen Proto-XX car chassis connection. The research methodology was conducted by testing the composition of materials and structural analysis using Ansys Workbench Release 15.0 software. The conclusion of the research is that the skeletal structure material uses Aluminum AA series 1XXX with Al content greater than 99.5%, the welding ability is low, causing a failure in the welded joint. The rivet connection failure is caused by the stress concentration in the rivet holes in the plates so that the connection crack propagation occurs.

Abstract

Two purposes of painting of the automobile body, i.e. protection and aesthetic. For the aesthetic one, scientifically measured its glossiness. The purpose of this study was to determine the effects of painting parameters using a spray to its glossiness. Three parameters varied were: (i) comparison of paint composition and thinner (1:1.2; 1:1.4 and 1:1.6), (ii) spraying distance (110 mm, 130 mm and 150 mm), and air pressure (3.5 bar; 4.5 bar and 5.5 bar, while the glossiness measured in gloss unit (GU) using a gloss meter. The experimental design method used was the response surface method with Box-Behnken design. A series of tests were carried out prior to ANOVA and optimization with Minitab: (i) lack of fit test, (ii) simultaneous parameter test, (iii) the coefficient of determination test, (iv) identical test, (v) independent test and (vi) normal distribution test. Out of three parameters, the most influential one is composition with a coefficient of mathematical equation of 6.592. In this study, the highest value in the 10th trial was 57.3 GU which was occurred when the parameters used were: distance of 130 mm, composition 1: 1.6 and pressure 3.5 bar. On the contrary, the smallest value GU in the 7th experiment was 35 GU with a distance of 110 mm, composition 1:1.4 and pressure 5.5 bar. From processing data using Minitab, the maximum gloss value was 58.76 GU with distance 116.86 mm, composition 1: 1.6 and pressure 3.5 bar. Keywords: painting, Box-Behnken design, gloss meter

Abstract

Cooling tower is defined as a heat exchanger whose working fluid is water and air which functions to cool water by direct contact with air To produce maximum performance from the cooling tower , a filler material is needed which functions to inhibit the flow of water. Rattan has smooth and strong properties against various conditions and is easy to make the desired shape. Previous research on cooling towers has shown that the work performance cooling tower is maximized by using fillers, one of which is using fiber, bamboo and aluminum as fillers.This cooling tower uses 3 layers of rattan filler with the distance between the fillers being equalized with 3 variations of the distance. In the process of testing the same treatment by varying the initial temperature 50 , 60 , 70 , air velocity 4 m/s, 6m/s, 8 m/s, and the distance between fillers 10 cm, 15 cm, 20 cm. Research on cooling towers with rattan as a filler resulted in higher cooling effectiveness and capacity than cooling towers without using fillers. This is evidenced by the highest effectiveness value on a cooling tower with filler material is 96.94%, while the highest value in the cooling tower without filler is 80.24%. The cooling capacity value in the cooling tower with filler is 11.23 kJ/s , while the highest value in the cooling tower without filler is 9.73 kJ/s. Keywords: Cooling Tower, Rattan, Effectiveness

Abstract

An electric car is a vehicle that is driven by an electric motor, the electric motor obtains power from electricity stored in the battery. Chassis is an important component in electric cars. Chassis is part of an electric car that functions as a support system in an electric car. In the chassis there is a maximum and minimum stress called the principal stress. This principal stress becomes a reference to determine the safety of the chassis. So it is necessary to know the principal stress on the chassis. The testing process uses two drivers, each of which weighs 45 kg and 56 kg. The tests were carried out at three different points on the electric car chassis. From the results of the principal stress test, σ1 = 3.3282 MPa and σ2 = 1.5429 MPa for the 45 kg driver and σ1 = 3.8233 MPa and σ2 = 2.1123 MPa for the 56 kg driver. The principal stress on the chassis is still in a safe condition because it does not exceed the yield stress of the chassis material.
