Abstract

The research carried out aimed to produce two model / equation, which are the surface roughness and the machining vibration.  The generated machining vibration model can be used as substitution parameter to predict surface roughness.Workpiece material used was aluminum-alloy. Aluminum alloys was processed on CNC machines of TU-3A. The first phase of the study (first year), the focus on the synthesis and study of theoretical models to determine the optimum level of accuracy that can be achieved from the model.Design and research methods are divided into several stages. Starting from preparation, cutting parameter settings, machining process, measurement, until to processing and data analysis. Based on the cutting parameters that have been designed before it, then the machining process is performed to obtain the data. Data obtained from the measurement of machinery vibration and surface roughness. Overall, the amount of data obtained from the machining process as many as 125 rows of data. Data processing done to obtain surface roughness and machining vibration equations coupled with the accuracy of each model. Model produced in this study were 5 (five) model, both of surface roughness and machining vibration. But from 5 (five) models,  only selected 1(one) model which has an optimum level of accuracy. In this study produced each 1 (one) model of surface roughness and 1(one) model of machining vibration couple with the accuracy of each model.The resulting model for surface roughness has a level of accuracy (theoretically) of 83,533%. While the model generated for machining vibration has the highest accuracy (theoretically) of 82,188%. Keywords: Spindle speed, feedrate, depth of cut, vibration machining, and surface roughness.

Abstract

Tujuan penelitian ini yaitu untuk menghasilkan produk pesawat tanpa awak (drone) dengan mengoptimalkan desain dan material rangka, mengukur centre of gravity, mengetahui kekuatan tarik dan regangan tarik dari beban rangka, serta mengetahui pengaruh beban terhadap durasi terbang. Tahapan penelitian meliputi: studi literatur, perencanaan gambar, analisa perancangan/beban, pengujian material dengan metode uji tarik untuk membandingkan kedua material (PLA dan karbon komposit), desain dan optimasi, uji coba terbang, dan analisa data, menghitung centre of gravity dan durasi terbang. Kesimpulan yang diperoleh dari rancang bangun drone untuk pertanian adalah: dimensi 270 × 350 × 170 mm, berat 1,26 Kg. ukuran propeller 5 Inc, daya angkat sebesar 12.72 N, jarak pengendalian 1000 meter, baterai Li-Po 1500 mAh. Titik pusat massa pada drone yang dibuat adalah X = -32,81mm, Y = -706,41mm, Z = 109,32mm. Kekuatan tarik secara aktual pada material PLA adalah 5,74 MPa dan material karbon komposit adalah 16,74 MPa. Kekuatan tarik secara simulasi pada material PLA adalah 5,548 MPa dan material karbon komposit 16,494 MPa. Durasi terbang dari drone menurun dengan bertambahnya beban yang diberikan. Pengunaan baterai tipe Li-Po 1500 mAh dapat menerbangkan drone dengan durasi terbang 7 menit 49 detik pada beban 500 gram.

Abstract

Proses pengecoran logam (casting) adalah salah satu teknik pembuatan suatu produk dengan cara logam dicairkan dalam tungku peleburan lalu lanjut dituang ke dalam ruang cetakan yang serupa dengan bentuk asli dari produk coran yang akan dibuat. Penelitian ini akan dirancang dan dibuat tungku berbahan bakar LPG. Tungku gas ini nantinya dibuat dan diaplikasikan sebaga alat peleburan logam bukan besi, Pada proses rancang bangun tungku gas diawali dengan pembuatan sketsa tungku, perencanaan ukuran dari benda kerja, kemudian proses pembuatan gambar kerja, pemilihan material, dan proses pembuatan Setelah pembuatan akan dilakukan pengujian sehingga alat ini akan menjadi penunjang praktikum terkhusus pada mata kuliah teknologi manufaktur dan teknologi bahan masi jarang digunakan. Kebanyakan dosen mengajarkan secara verba kepada mahasiswa tanpa ada alat yang mendukung. Salah satu penyebabnya adalah tidak tersedianya alat tungku peleburan logam. Tujuan tugas akhir ini untuk menciptakan tungku krusibel untuk peleburan logam non ferro (Aluminium dan Kuningan) dengan kapasitas 5kg berbahan bakar gas.

Abstract

The goals of this CNC router machine development research are develop the control system for the CNC router using Mach3, improve product quality with a clamping system, increase the machine's production capacity from initially handling just one workpiece, and estimate the costs of developing the CNC router machine. The research stages include literature review, design (design & drawing), selection and procurement of mechanical and control materials, function and component compatibility checks, construction and assembly of mechanical and control systems, data analysis, and conclusions. Data collection methods involve using different materials, such as acrylic and MDF, and measuring the precision in product manufacturing. The research concludes that the control system development for the CNC router using Mach3 has been successful. The designed control system employs Nema 23 stepper motors as actuators and Mach3 as the CNC software. This system can control the CNC machine’s movement on the X, Y, and Z axes according to the input program. The use of clamps on the CNC router ensures the workpiece remains stationary, preventing errors in cutting or engraving. Additionally, using a stopper or workpiece placement device on the CNC router facilitates easier installation and quick workpiece replacement, thereby enhancing productivity.
