“…Untuk proses cutting material menggunakan CNC laser cutting, penelitian yang telah dilakukan adalah menggunakan teknik DoE dalam melakukan optimasi [7], selanjutnya penelitian menggunakan DoE untuk menentukan komposisi faktor optimal dalam proses cutting berdasarkan parameter multi respon [8]. Terkait parameter multi respon tersebut beberapa penelitian telah ditujukan untuk material plat logam (metal sheet) [9], logam yang lebih spesifik berjenis stainless steel [10], dan bahkan lebih spesifik lagi berdasarkan ketebalan stainless steel tersebut [11]. Selain logam, material lain dalam penelitian terkait optimasi proses cutting adalah kayu [12], plastik polimer [13], bahan polimer yang lebih spesifik yaitu polikarbonat [14], dan bahkan material komposit seperti Al6061/SiCp/Al2O3 [15].…”

<p>Artikel ini membahas penelitian terkait optimasi komposisi level setup proses engraving mesin CNC laser cutting tipe G-Weike LC6090 terhadap material akrilik. Penelitian ini dibutuhkan karena tidak adanya acuan tabulasi level setup proses engraving pada mesin tersebut, sehingga setup proses hanya berdasarkan perkiraan. Hal ini memunculkan masalah terkait kualitas hasil proses, efisiensi permesinan, dan masa pakai tabung CO2 penghasil laser. Artikel ini memperlihatkan hasil optimasi komposisi level setup optimal proses engraving menggunakan Design of Experiment (DoE) dengan metode Simplex Centroid Design (SCD) dan optimasi multi respon. Faktor komposisi setup dalam penelitian ini adalah kecepatan proses, kekuatan, dan interval pemakanan laser. Sedangkan parameter multi respon yang diukur adalah waktu proses, depth, dan roughness. Model formulasi matematis akan dihasilkan dari setiap parameter responnya, kemudian dilakukan optimasi respon tersebut berdasarkan depth yang diinginkan. Hasil penelitian menunjukkan terdapat trade off dari parameter multi responnya, serta diperoleh komposisi level setup optimal untuk batas depth (p) 0,3 mm ≥ p ≤ 1,34 mm.</p>

“…Process parameters namely laser power (LP), cutting speed (CS) and gas pressure (GP) are considered in the present study. Levels of process parameters as listed in Table 3 are selected on the basis of literature review [1,4,6]. Some trial runs were taken to determine the range of process parameters suitable for the experimental conditions (i.e., laser power, cutting speed and gas pressure).…”

The present paper describes an experimental study on influence of process parameters on dross properties in laser machining of AISI 304 material. Process parameters namely laser power, cutting speed and gas pressure are considered in the present work. Design of experiments is done using response surface methodology and analysis of variance is performed in order to identify significance and influence of process parameters on dross height. It is found that laser power and gas pressure are most significant parameters followed by cutting speed. Dross height increases with increase in laser power and decreases with decrease in gas pressure. On the basis of experimental analysis, a second order mathematical model is developed to predict dross height. Model predictions and experimental results are found in reasonable agreement. Further, optimization of process parameters is also performed to minimize dross height

“…Az utóbbi években a szállézerek teljesítményének erőteljes növelésével sikerült nagy vastagságú korrózióálló acéllemezt elvágni, Seon és társai 9 kW-os szállézerrel 60 mm-es vastagságot sikerült elvágni, de a felület nagyon salakos [1]. Külön problémát jelent a vastag acélok ívelt vágása [2,3]. Berkmanns és Faerber a teljesítmény mellett az íveltség hatását is vizsgálja a vágott felület minőségére [2].…”

Nowadays, laser technology has become an essential part of our lives. The great advantage of lasers used in materials processing is that they provide very precise, quick machining and low heat input. However, all machining requires unique parameters. These parameters are for example: Power, wavelength, cutting speed and focus line distance. Using optical microscopes and electron microscopes to examine the cutting surfaces of the CO 2 laser, we can see that the cut has high quality surface (cutting 3,25 mm thick plates), but holes made with a solid-state laser have micro-cracks on the inner side. These cracks are not acceptable to the customers.
