Ahmad, Firman Andi (2019) Pengaruh Spindle Speed dalam Proses Drilling terhadap Laju Korosi pada Stainless Steel 316L Menggunakan Mesin CNC Milling. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini bertujuan untuk mengetahui pengaruh dari parameter proses permesinan pada proses drilling menggunakan mesin CNC TU-3A terhadap laju korosi pada material stainless teel AISI 316L. Proses drilling disini nantinya mengasilkan permukaan lubang yang berbeda berdasarkan variasi spindle speed yang digunakan, yaitu menggunakan variasi spindle speed 1800 rpm, 1600 rpm, 1400 rpm. Permukaan yang telah dilakukan proses drilling selanjutnya dilakukan uji kekasaran permukaan. kekasaran permukaan sangat dipengaruhi oleh spindle speed yang digunakan dalam proses drilling, dimana semakin kecil spindle speed yang digunakan menghasilkan nilai kekasaran permukaan yang semakin besar. Dari hasil pengujian kekasaran permukaan didapatkan yaitu kekasaran permukaan rata-rata tiap variasi yaitu 0.942 μm, 1.381 μm dan 1.753 μm. Pada pengujian laju korosi juga didapatkan korelasi hubungan antara kekasaran permukaan dengan laju korosi pada material stainless steel 316L, yaitu semakin tinggi nilai kekasaran permukaan maka laju korosinya juga akan meningkat. Hasil dari Pengujian laju korosi didapatkan nilai dari laju korosi ratarata yaitu 0,205454 mm/year, 0.61112 mm/year dan 1.35606667 mm/year.
English Abstract
This study aims to determine the effect of spindle speed in the drilling process on the corrosion rate of 316L stainless steel using cnc milling machines. The drilling process will produce different hole surfaces based on the spindle speed variations used, with a spindle speed variation 1800 rpm, 1600 rpm and 1400 rpm. The surface that has been carried out by the drilling process is then testing of surface roughness. Surface roughness is strongly influenced by the spindle speed used in the drilling process, where the smaller the spindle speed used results in a greater surface roughness value. From the results testing of surface roughness was found that the average surface roughness of each variation was 0.942 μm, 1.381 μm and 1.753 μm. Corrosion rate testing also found a correlation between the surface roughness and the corrosion rate of 316L stainless steel material, namely the higher the surface roughness value, the corrosion rate will also increase. The results of testing the corrosion rate obtained values of the average corrosion rate of 0.205454 mm/year, 0.61112 mm/year and 1.35606667 mm/year.
