Abstract

Plate working practicum is one of the learning activities in the Mechanical Engineering Department, Bandung State Polytechnic. The use of practicum tools can facilitate students and lecturers in carrying out these activities. The problem encountered during plate working practicum is the limited availability of tools to press the edges of prism-shaped workpieces made by students. This leads students to use alternative tools such as plate bending tools, clamps, and hammers, which are less effective as they take longer and risk damaging the material due to uneven pressure. Based on this issue, the design and creation of a pressing tool is necessary to support the plate working practical activity. The mechanism of this tool uses the pressing force of a punch to shape or cut the workpiece according to the desired form and size. The design of this tool uses the Pahl & Beitz method, considering safety, ease of use, and ease of manufacturing. The final specifications of the press tool have dimensions of 300x250x253 mm, a tool weight of 47.3 kg, and a tool capacity to press plates up to 1 mm thick. Tests were conducted on ST37 steel plates with a thickness of 1 mm and plates with a thickness of 0.5 mm, demonstrating that the press tool can function effectively in the hemming process, both on 1 mm thick plates and prism-shaped workpieces.

Abstract

The pineapple leaf processing machine is used to process agricultural waste that is typically discarded into economically valuable products. One important aspect in the design of this machine is ensuring that it can operate safely and effectively. Therefore, finite element analysis (FEA) numerical simulations are used to predict the behavior of the machine and optimize its design. The purpose of performing finite element analysis on the decorticator blade is to analyze whether the design model experiences plastic deformation and to predict the forces occurring during machine operation, ensuring that the machine can withstand the given load without damaging its structure. The material used for the Decorticator Blade is SS 304, consisting of 12 blades. The simulation process conducted in this research is divided into three stages: Pre-processing, Simulation, and Post-processing. The simulation process is performed 10 times using the curvature-based mesh method, with mesh sizes set to 10, 9, 8, 7, 6, 5.8, 5.6, 5.4, 5.2, and 5. The maximum stress that occurs and meets the convergence target is at mesh sizes 5.6, 5.4, and 5.2, with respective values of 44.43 MPa, 44.41 MPa, and 44.39 MPa, with the largest error accuracy of 2.49%. The results of the finite element analysis show that the design of the Decorticator Blade has a stress of 44.43 MPa and a Factor of Safety (FoS) of 6.6. Through this simulation, the design of the Decorticator Blade can be used in the machine for processing pineapple leaves into fibers.

Abstract

3D Printing is the process of creating 3D objects from CAD models. 3D printing technology is used to make various objects ranging from toys to components on machines. The advantages of this method allow the manufacture of prototypes at low cost and shorter processing time than other methods. Reverse engineering is the process of analyzing existing products as a reference to design similar products by minimizing and increasing product advantages. With the reverse engineering method, the performance principle of a tool, object, or system can be done by analyzing its structure, function, and operation. The purpose of this research is to be able to redesign the 3D Printing Machine so that students and lecturers can transfer technology and maintain in the development of 3D Printing machines made by domestic children. The output in this study is a 3D Printing machine that can operate with an area of 500x500 mm. The results of this study include, 1). This Innova Big Print 3D Printing Machine can be developed and upgraded into a Reliable 3D Machine. 2).This 3D machine can be increased in speed from 60 mm/s to 120 mm/s, This has experienced a very significant increase. 3). This 3D Print machine can already transfer data using wifi so that it makes it easier in the printing process.

Abstract

Mesin perkakas CNC (Computer Numerically Controlled) merupakan alat yang sangat penting dan banyak digunakan dalam proses manufaktur produk. Mesin perkakas CNC adalah suatu mesin perkakas yang dikendalikan oleh komputer menggunakan kode angka dan huruf sehingga secara otomatis menjalankan operasi pemesinan sesuai dengan perintah yang tersusun dalam kode-kode tersebut. Jika dibandingkan dengan mesin perkakas konvensional yang setaraf dan sejenis, mesin perkakas CNC lebih unggul baik dari segi ketelitian, ketepatan, fleksibilitas, dan kapasitas produksi. Salah satu mesin CNC yang banyak digunakan di Indonesia adalah Mesin Milling CNC EMCO TU-3A buatan EMCO Austria. Mesin ini biasanya digunakan oleh institusi pendidikan untuk mendukung praktikum. Namun, karena teknologi yang sudah tidak kompatibel (tidak mendukung teknologi CAM - Computer Aided Manufacturing) dan tidak sesuai dengan standar industri, mesin ini sudah jarang digunakan lagi. Bahkan pada beberapa institusi, mesin ini hanya tersimpan di gudang atau dibuang begitu saja. Hal ini tentu menyebabkan kerugian bagi institusi tersebut. Oleh karena itu, diperlukan solusi untuk menyelesaikan permasalahan tersebut. Salah satunya adalah dengan merekayasa ulang mesin tersebut dengan spesifikasi yang lebih baik serta kompatibel dengan teknologi saat ini, yaitu teknologi CAM. CAM merupakan teknologi komputer yang mengubah desain tiga dimensi pada komputer menjadi gerak operasi sebuah mesin sehingga dapat menghasilkan benda yang sesuai dengan desain. Proses ini melibatkan dua tahapan, yakni: mengubah desain tiga dimensi menjadi kode yang dipahami oleh mesin, kemudian mengontrol mesin berdasarkan kode tersebut. Penelitian ini menghasilkan mesin Milling CNC yang memiliki kemampuan ketelitian operasi 0.005 mm dengan mengintegrasikan prototipe kontrol dengan teknologi CAM ke dalam mesin.

Abstract

Finite element numerical simulation (FEA) has a function to analyze the design model and as a validation of the analysis results against manual calculations. FEA simulation uses specialized software to save time and cost. The purpose of the FEA simulation on this design model is to analyze the strength of the design model against a deformation. In this study, a strength test will be carried out on one of the sub-assemblies on the fishing equipment tensile and compressive testing machine, namely the fishing tools holder sub-assembly. The reason for the simulation is that the sub-assembly is directly related to compressive or tensile forces with relatively large units. The material used for this sub-assembly design is SS400 material or ASTM A36 Carbon Steel. The simulation process was carried out in 10 iterations using the curvature-based mesh method with mesh size settings of 10, 9, 8, 7, 6, 5.8, 5.6, 5.4, 5.2, and 5. The maximum stresses that occurred and reached convergence were at mesh sizes 5.8, 5.6, 5.4, and 5.2 in sequence with stress values of 137 MPa, 136 MPa, 142 MPa, and 135.7 MPa, respectively. The finite element analysis results show that the fishing tools holder design produces a maximum stress of 142 MPa at the converging area, with a factor of safety (FoS) of 1.8. Based on these simulations, the design of the fishing tools holder can be implemented on the Fishing Equipments Tensile Test and Press Test Machine.
