Abstract

Abstract                  The experimental study of the influence of process parameters towards collar height on incremental backward hole-flanging (IBHF) process with aluminium plate workpiece was presented in this paper. The effect of process parameters toward collar height which produced by IBHF process was investigated. Experiments were performed with a CNC machine, a 30o conical forming tool, and aluminium plates. The process parameters are feed speed with two levels, radial forming step size with three, and axial forming step size with three levels. Some parameters were kept constant, i.e., spindle speed, initial hole diameter, final hole diameter, and conical forming tool diameter. Digital Vernier caliper was used to measure the height of the collar. Experimental results of IBHF process have shown that the feed speed (vf) parameter has no effect toward collar height. Increased radial forming step size (Δx/y), increased the collar height also. Increased the axial forming step size (Δz) reduced the collar height. Keywords: hole-flanging, incremental sheet metal forming, incremental backward.

Abstract

Conventional hole-flanging process in a small batch is sometimes costly or almost impossible due to the variety of the product profile. Recent studies showed that modern manufacturing was developed to overcome the limitation of the conventional hole-flanging process. Incremental backward hole-flanging (IBHF) was one of the strategies that developed to overcome this particular limitation. The main objective of this research was to investigate the influence of IBHF process parameters toward collar thickness of the product. It enables to measure the impact and behavior of each process parameters, i.e., forming speed, axial and radial forming step size toward the particular response parameter. The result showed that axial and radial forming step size was the main influence and the forming speed has a slight effect towards collar thickness. The behavior of each parameter was increased forming speed and radial forming step size would decrease collar thickness, whereas increased axial forming step size would increase collar thickness.

Abstract

Metal cutting process (cutting process) is to cut metal to get the shape and size and quality of the planned cutting surface. The metal cutting process is carried out with special tools, according to the type of cutting process. So the tools for one process cannot be used in another process, even for similar processes, the tools cannot be exchanged if the cutting plans are not the same. Lathe process is a machining process to produce cylindrical machine parts which are carried out using a Lathe. Its basic form can be defined as the machining process of the outer surface of cylindrical or flat lathe objects. Polyvinyl Chloride, commonly abbreviated as PVC, is the third-order thermoplastic polymer in terms of total usage in the world, after Polyethylene (PE) and Polypropylene (PP). Worldwide, more than 50% of PVC produced is used in construction. PVC is produced by polymerizing vinyl chloride monomers (CH2 = CHCl). Because 57% of its mass is chlorine, PVC is the polymer that uses the lowest petroleum feedstock among other polymers. This research follows up the selection of configuration of the lathe machining process using plastic work pieces. In this study, Maximat V13 lathe and PVC type plastic were used. The variation of machining processes are spindle rotation (320, 540, and 900 rpm), feeding speed (0.07, 0.14, and 0.28), the use of tool types (carbide and HSS) and cooling (without cooling, coolant, and oil). So, with this research, it is expected that the optimal parameters in determining the configuration of the lathe machining process on a PVC work piece to produce a good turning surface can be achieved

Abstract

Pembentukan logam masuk dalam sebuah kelompok besar dari proses-proses manufaktur. Pembentukan logam menggunakan deformasi plastis untuk mengubah bentuk benda kerja. Deformasi atau perubahan bentuk dihasilkan dari penggunaan tool yang biasanya disebut die (cetakan). Cetakan tersebut memberikan tegangan yang melebihi kekuatan yield logam (plastis). Logam selanjutnya berubah bentuk menjadi bentuk yang sesuai dengan geometri cetakan. Pembetukan flens pada lubang disebut hole-flanging. Hal ini dimaksudkan untuk memperkuat bagian tepi dari lubang atau untuk tujuan membuat ulir. Untuk pelat logam yang tipis proses ini bisa dibuat bersamaan dengan proses piercing. Proses hole-flanging ini berfungsi untuk menyediakan luasan pengikatan pada sambungan-sambung pipa. Proses hole-flanging ini kemudian dikembangkan dengan metode bertahap yang menggunakan cetakan yang sangat sederhana. Proses pembentukan ini disebut dengan incremental hole-flanging. Pada pembuatan flens untuk percabangan maupun pengikatan pada lingkungan kerja yang tertutup, proses hole-flanging konvensional tidak mampu dilakukan dengan prinsip pembentukan ke dalam. Proses pembuatan flens untuk kasus seperti ini digunakan metode incremental backward hole-flanging. Pada penelitian ini akan dianalisa karakter deformasi dari benda kerja alumunium dengan metode incremental backward hole-flanging terhadap laju pembentukan. Dimana mesinyang digunakan pada penelitian ini adalah mesin CNC 3-axis dengan parameter laju pembentukan sebesar 500, 1000, 1500, dan 2000 mm/min.

Abstract

Fiber metal laminates or commonly known as fiber metal laminates (FML) are composite structures made by combining 2 layers of material as the outer layer with the core material. The outer layer of this composite is called the laminate. Generally, laminated composites are produced by joining techniques under solid-state conditions, such as diffusion bonding, extrusion, friction-stir welding, and roller welding. In this study, glass fiber composites with aluminum lamination were made using the vacuum assisted resin infusion (VARI) method, using epoxy resin. The surface treatment of the aluminum laminate was carried out with the direction of roughing at certain angles and variations of the surface roughening of the laminate to test the mechanical bonding between the composite and the laminate. Mechanical bonding testing using three-point bending test method (three-point bending) and buckling test. The expected result is that by surface treatment on aluminum laminate, the best mechanical bonding to composites with glass fiber is obtained. The TKT to be achieved from this research is TKT level 3, which is an analytical study that supports the prediction of the performance of the effect of the bonding surface treatment on the mechanical properties of glass fiber composites with aluminum lamination.

Abstract

Aerodynamics is a branch of science that discusses the movement of an object in the air. Aerodynamics comes from the words aero = air and dynamics = force of motion. The study of air forces is a branch of fluid mechanics. This study is a continuation of the study of hydrodynamics, where the science of the motion of air has a close relationship with other sciences. Physics, mathematics, mechanics, meteorology and others are branches of science that are closely related to aerodynamics. Where in the science of aerodynamics, it discusses the principle of stationary air, specifically about the changes experienced by the air when there is a change in geometry. In this study, CFD analysis was carried out to inspect and optimize the airflow through the energy-efficient car body "Ken dedes Evo 3" Malang State Polytechnic to participate in energy-efficient car competitions by following the regulations and packaging requirements in energy-efficient car contests.

Abstract

Potensi sumber alam di lingkungan sekitar berupa ketersediaan sumber makanan kambing yang melimpah RT04/RW2, Desa Pakis, Kecamatan Durenan, Kabupaten Trenggalek, pada tahun 2017 telah mulai dimanfaatkan oleh mitra untuk usaha pemeliharaan kambing sebagai upaya dalam meningkatkan kemampuan ekonomi rumah tangga. Dari proses pemeliharaan yang baik dan ketersediaan sumber makanan yang melimpah, sampai dengan sekarang sudah berhasil dibudidayakan 12 ekor kambing dari awal pembudidayaan sejumlah 2 kambing calon indukan. Dalam perjalanannya, dalam menekuni usaha ini, ditemui kendala utama yang menghambat kemajuan dari usaha ini, yaitu kendala kurang idealnya kandang kambing yang ada untuk dapat mendukung keberhasilan usaha tsb. Konstruksi, sanitasi, dan luasan kandang yang ada belum cukup ideal sebagaimana telah diatur atau dipandu dalam suatu Peraturan Menteri Pertanian yang ada. Diyakini bahwa apabila kendala-kendala ini dapat diselesaikan maka akan dapat meningkatkan keberhasilan usaha ini, bahkan berpotensi untuk bisa menjadi model usaha pemeliharan kambing sekala kecil rumah tangga yang dapat dijadikan rujukan rujukan bagi calon-calon pemula usaha pemeliharaan kambing. Sebagai solusinya kepada mitra diberikan pelatihan untuk merancang kandang kambing yang ideal dengan mengacu kepada Peraturan Menteri Pertanian yang ada yang selanjutnya kepada mitra dilatih untuk membuat kandang kambing yang telah dirancang.

Abstract

Almost of kids in the world still bring a lunch box and a bottle of water in their bag when their go to school. His mother always prepares a lunch box complete with a bottle of drinking water, hoping that his son can enjoy his favorite lunch and avoid starvation. Sometimes the mother is very worried when the lunch box has been brought by the child but the water bottle is left behind. Then the mother was willing to take her child's water bottle to her school. This is certainly not expected by either the mother or the child. As a form of concern for the author to this problem, the author proposes a lunch box design with a lunch box lid that also functions as a drinking water bottle. The idea of this design proposal is ones grab, both are food & drink in your hand. The goal is how to make a kids can grab their food and drink easily and practice. So it is proposed to modify a top cover of common foodpack to become a drink bag. The design process begins with analyzing market needs, making sketches, creating 3D design models using the Autodesk Inventor CAD application, material selection, and product evaluation.
