Manik, Arnov Toto and Ir. Tjuk Oerbandono, MSc.CSE and Ir. Ari Wahjudi, MT. (2023) Pengaruh Spindle Speed terhadap Surface Roughness SS316L pada Face Milling dengan Metode NMQL Minyak Kanola dan ZnO. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini dilakukan untuk mengetahui pengaruh variasi spindle speed terhadap nilai kekasaran permukaan spesimen SS316L proses face milling dengan metode Nanofluids Minimum Quantity Lubrication pelumas minyak kanola dan ZnO. Variasi spindle speed dan konsentrasi berat ZnO secara berturut turut adalah 3780rpm; 4200rpm; 4620rpm dan 0%;0,5%;1%. Kemudian spesimen SS316L yang telah dilakukan proses milling dilakukan berbagai pengujian seperti kekasaran permukaan dengan menggunakan Surface Rughness Tester Mitutoyo SJ-301, analisa statistik metode regresi linear menggunakan software Minitab, dan foto makro dari spesimen dan pahat. Hasil kekasaran permukaan paling tinggi didapatkan oleh variasi spindle speed 3780rpm dan 0% ZnO yaitu 0,368μm dan kekasaran permukaan paling rendah oleh variasi spindle speed 4620rpm dan 1% ZnO yaitu 0,258μm. Hasil metode regresi linear menunjukan persamaan Ra = 0,5233 – 0,000039(spindle speed) – 0,07333(%ZnO), R-Sq sebesar 97,1% dan nilai F Hitung sebesar 100,4. Hasil penelitian menunjukkan semakin tinggi nilai spindle speed maka akan semakin rendah nilai kekasaran permukaan dan semakin banyak konsentrasi ZnO dalam minyak kanola akan menurunkan nilai kekasaran permukaan.
English Abstract
This research was conducted to determine the effect of spindle speed variations on the surface roughness value of SS316L in the face milling process using the Nanofluids Minimum Quantity Lubrication method using canola oil and ZnO as lubricants. Variation of spindle speed and weight percentage of ZnO respectively is 3780rpm; 4200rpm; 4680rpm and 0%;0.5%;1%. The SS316L specimen that had been milled was subjected to various tests such as surface roughness using the Mitutoyo SJ-301 Surface Rughness Tester, statistical analysis of the linear regression method using Minitab software, and digital macro photos of the specimen and milling cutter. The highest surface roughness results were obtained by the spindle speed variation of 3780rpm and 0% ZnO, which is 0.368μm and the value of the lowest surface roughness by the spindle speed variation of 4680rpm and 1% ZnO, namely 0.258μm. The results of the linear regression method show the equation Ra = 0.5233 – 0.000039(spindle speed) – 0.07333(%ZnO), R-Sq is 97,1% and the calculated F value is 100.4. The results showed that the higher the spindle speed value, the lower the surface roughness value and the more ZnO concentration in canola oil, the lower the surface roughness value.
