“…Kandungan pada laser cutting memiliki nilai Fe 0.5%, Si 0.5% Cu 4.9%, Mn 0.9%, Mg 1.8%, Zn 0.25%, Cr 0.1% dan Ti 0.15%. Campuran tersebut memberikan hasil pemotongan laser cutting yang baik (Cavusoglu, 2021a). Proses pemotongan material aluminium menggunakan laser cutting memberikan kemudahan dalam segi waktu dan jumlah hasil potongan, karena proses pemotongan aluminium menggunakan laser cutting dapat bekerja secara otomatis menggunakan sistem CNC (Hasan & Herianto, 2014).…”

“…Pendekatan penelitian ini adalah diadaptasi dari penelitian Cavusoglu dan teman-teman yang membahas pengaruh permukaan akibat hasil pemotongan laser cutting terhadap material Aluminium yang terjadi pada permukaan benda potong. Hasil permukaan benda potong akan diamati dan diukur permukaannya serta mengumpulkan data hasil pengukuran tersebut untuk dilakukan rata-rata cacat timbul tertinggi" (Cavusoglu, 2021b). Metode penelitian yang dikembangkan untuk memperoleh hasil kecacatan pada material aluminium alloy dapat dilihat pada Gambar 2.…”

Laser cutting has been widely used and is growing rapidly in the manufacturing industry, both in the automotive sector and other production fields as needed for fast, precise and accurate cutting processes. Cutting using laser cutting makes it very easy for the production industry to cut steel, aluminum and other materials. However, errors that often occur at this time when input parameters are carried out in the operation of CNC laser cutting often result in defects in the cut material. The purpose of this study was to determine the variation of speed parameters for cutting aluminum alloy type 1050A material with a thickness of 0.8 mm. With these speed variations, it can be seen at what speed the material corresponds to during the laser cutting process. The method in this study was to use an experimental method with variable speeds of 33 mm/s, 55 mm/s and 88 mm/s, then look at the defects that arise and make measurements arising from the flatness of the plate using a digital dial indicator. The results of this study showed that the highest defects were on the average of sections A3 and B3 of 0.012 mm with a plate diameter of 50.2 and 45.2 mm with an aluminum plate thickness of 0.8 mm. At a speed of 33 mm/s, it can be concluded that the appearance of these defects is very small, ranging from 0.004 mm-0.008 mm.Keywords:Laser Cutting; Arise Defects; Aluminum Alloy.__________________________ AbstrakPemotongan laser cutting telah banyak digunakan dan berkembang pesat di dunia industri manufaktur, baik di bidang otomotif maupun bidang produksi lainya sebagaimana dibutuhkan untuk proses pemotongan secara cepat, tepat dan akurat. Pemotongan menggunakan laser cutting sangat memudahkan bagi para industri produksi dalam memotong sebuah material baja aluminium dan material-material lainnya. Namun kesalahan yang sering terjadi pada saat ini apabila input parameter yang dilakukan dalam pengoperasian CNC laser cutting sering terjadi kecacatan pada material hasil potongan tersebut. Tujuan dari penelitian ini adalah dengan menentukan variasi parameter kecepatan terhadap pemotongan material aluminium alloy tipe 1050A ketebalan 0,8 mm. Dengan variasi kecepatan tersebut dapat dilihat pada kecepatan berapa yang sesuai dengan material tersebut pada saat proses laser cutting. Metode pada penelitian ini adalah menggunakan metode eksperimen dengan variable kecepatan sebesar 33 mm/s, 55 mm/s dan 88 mm/s, selanjutnya melihat cacat timbul dan melakukan pengukuran yang timbul dari kerataan plat menggunakan dial indikator digital. Hasil penelitian ini menunjukkan cacat timbul tertinggi pada rata-rata bagian A3 dan B3 sebesar 0,012 mm dengan diameter plat 50,2 dan 45,2 mm pada ketebalan plat aluminium 0,8 mm. Pada kecepatan 33 mm/s dapat disimpulkan bahwa timbulnya cacat tersebut sangat kecil berkisar antara 0,004 mm-0,008 mm. Kata Kunci:Laser Cutting; Cacat Timbul; Aluminium Alloy.

Sheet metals such as titanium alloys, steel alloys, and aluminum alloys are significant materials due to their importance among everyday life products as well as high-strength applications in aircraft, ships, automobiles, construction, military, and marine purposes. Recently, laser cutting is one of the best and fastest non-conventional methods to cut sheet metals, so it is necessary to understand how laser cutting parameters affect cutting quality. A comprehensive review was presented to investigate how laser cutting parameters affect the cut surface and kerf quality and which parameters affect cutting quality the most. An overview of the advantages of laser cutting when compared to other methods of machining was presented. In addition, a description of the laser cutting method and the different sources of laser were presented with clearing the range of thicknesses of the cut material for each source and their advantages. Also, a description of the properties and the applications of the studied materials were discussed. The performance parameters ofcutting were illustrated in detail by graphs and equations. The research analysis and discussion were discussed in such organized details by tables and graphs which show the full classification of the studied papers. It was found that the best conditions to obtain low surface roughness, small HAZ width, small kerf width, and small kerf angle are using low laser power, high cutting speed, medium gas pressure, high standoff distance, medium pulse frequency, medium pulse width, small nozzle diameter, small thickness, and nitrogen as an assist gas.
