Irfan, Muhammad (2018) Pengaruh Cutting Speed, Depth of Cut, dan Feed Terhadap Kekasaran Permukaan Material Kalsit Hasil Mesin Bubut. Sarjana thesis, Universitas Brawijaya.
Abstract
Kalsit termasuk ke dalam salah satu jenis mineral non logam yang saat ini penggunaannya sudah merambah ke berbagai macam industri. Kalsit dalam bentuk batu alam oniks dijadikan sebagai bahan dasar dalam membuat berbagai kerajinan tangan yang saat ini proses pembuatannya sudah menggunakan mesin bubut. Dalam dunia industri manufaktur, kekasaran permukaan menjadi salah satu aspek penting yang diperlukan dalam proses permesinan karena dijadikan sebagai salah satu pertimbangan dalam kualitas suatu produk. Pembubutan merupakan salah satu dari berbagai macam proses permesinan dimana pahat potong bermata tunggal menghilangkan lapisan terluar benda kerja yang berotasi. Pahat melakukan pemakanan secara linier searah dengan sumbu rotasi sehingga terbentuk benda kerja dengan geometri silindris. Dalam operasi pembubutan terdapat beberapa parameter yang mempengaruhi kekasaran permukaan diantaranya cutting speed, feed, dan depth of cut. Penelitian ini ditujukan untuk mengetahui sejauh mana pengaruh parameter permesinan yaitu cutting speed, feed, dan depth of cut terhadap kekasaran permukaan material kalsit hasil proses pembubutan. Spesimen yang diuji dalam penelitian ini didapatkan di daerah Gamping, Tulungagung dan dibubut sampai membentuk seperti gelas di daerah yang sama. Untuk pengujian XRD dan XRF dilakukan di Laboratorium Energi dan Lingkungan Institus Teknologi Sepuluh November (ITS) sedangkan untuk uji kekerasan material dilakukan di Laboratorium Metalurgi Fisik Teknik Mesin Universitas Brawijaya dengan menggunakan alat uji Rockwell Hardness Tester. Variasi parameter permesinan yang digunakan dalam penelitian ini adalah cutting speed 66 m/min, 110 m/min, 154 m/min, kemudian feed 0,1 mm/rev, 0,2 mm/rev, 0,3 mm/rev dan cutting speed 0,3 mm, 0,45 mm, 0,6 mm. Proses pembubutan ulang spesimen dengan parameter yang telah ditentukan dilakukan di Laboratorium Proses Produksi I Teknik Mesin Universitas Brawijaya lalu untuk uji kekasaran permukaannya dilakukan di Laboratorium Metrologi Industri Teknik Mesin Universitas Brawijaya dengan menggunakan alat ukur Mitutoyo SJ-210 Surface Roughness Tester. Data kekasaran permukaan yang diperoleh kemudian diolah dan ditabulasi dengan menggunakan metode statistik ANOVA. Dari hasil penelitian menunjukkan bahwa cutting speed memiliki kecenderungan berbanding terbalik dan feed berbanding lurus terhadap kekasaran permukaan yang dihasilkan. Nilai kekasaran permukaan terendah diperoleh spesimen dengan variasi cutting speed 154 m/min, feed 0,1 mm/rev dan depth of cut 0,3 mm yaitu 2,004 μm. Sedangkan nilai kekasaran permukaan tertinggi yaitu 4,200 μm diperoleh spesimen dengan variasi cutting speed 66 m/min, feed 0,2 mm/rev dan depth of cut 0,3 mm. Berdasarkan uji analisis ragam, satu-satunya parameter yang berpengaruh terhadap kekasaran permukaan material kalsit hanyalah cutting speed.
English Abstract
Calcite is included in one type of non-metallic mineral which currently has been used in various industries. Calcite in form onyx natural stone is used as basic material for making various handicraft which are now to make those stuff have been using lathe machine. In the world of manufacturing industry, surface roughness is one of the important aspects needed in the machining process because it is used as one of the considerations in the quality of a product. Turning is one of the various machining processes where a single-edged cutting tool removes the outermost layer of rotating workpiece. The cutting tool performs linear feeding in the direction of the rotation axis so that the workpiece is formed with cylindrical geometry. In turning operations there are several parameters that affect surface roughness including cutting speed, feed, and depth of cut. The aim of this research is to determine the influence of machining parameters cutting speed, feed, and depth of cut on the surface roughness of calcite material resulting from the turning process. The Specimen used in this study were obtained in the Gamping district, Tulungagung and were lathed to form a glass in the same area. XRD and XRF test were carried out at Energy and Environtment Laboratory Ten November Institute Technology while for material hardness testing carried out at the Physical Metallurgy Laboratory of Mechanical Engineering Brawijaya Universityby using Rockwell Hardness Tester. In this study the variations used are cutting speed 66 m / min, 110 m / min and 154 m / min then feed 0.1 mm / rev, 0.2 mm / rev, and 0.3 mm / rev while the depth of cut 0.3 mm, 0.45 mm, and 0.6 mm. The process of turning specimen with predetermined parameters was carried out at the Process Production Laboratory I of Mechanical Engineering Brawijaya University then for surface roughness testing carried out at the Metrology Industry Laboratory of Mechanical Engineering Brawijaya University using Mitutoyo SJ-210 Surface Roughness Tester. Surface roughness data obtained were then processed and tabulated using ANOVA statistics method. From the results of the research showed that cutting speed has a tendency to be inversely proportional and the feed is directly proportional to the resulting of surface roughness. The lowest surface roughness value was obtained by specimens with a cutting speed variation of 154 m / min, feed 0.1 mm / rev and a depth of cut of 0.3 mm which was 2.004 μm. While the highest surface roughness value of 4,200 μm was obtained by specimens with variations in cutting speed of 66 m / min, feed 0.2 mm / rev and depth of cut 0.3 mm. Based on the variance analysis test, the only parameter that influences the surface roughness of calcite material is cutting speed.
