Abstract
Penelitian ini dilakukan untuk menentukan pengaruh besaran cutter speed, feed rate dan dept of cut pada proses CNC Frais/Milling terhadap nilai kekasaran baja AISI 1045. Proses frais yang dilakukan menggunakan pendingin dromus dengan variasi cutter speed antara 200 rpm s.d 350 rpm, variasi feed rate antara 14 mm/menit s.d 59,5 mm/menit dan variasi dept of cut 0,5 s.d 1,5 mm. Hasil dari proses frais untuk setelah dilakukan pengukuran kekasaran dan data nilai kekasaran tersebut diproses dengan menggunakan program SPSS 20 dihasilkan suatu bentuk formula regresi ganda Y = 6,473 + 0,004 X1 – 0,028 X2 – 0,422 X3, yang menyatakan bahwa 85,4% besarnya cutter speed, feed rate dandept of cut berpengaruh terhadap nilai kekasaran dan 14,6% nilai kekasaran dipengaruhi oleh gesekan chip terhadap benda kerja, kondisi pisau frais/cutter dan kesalahan teknis lainnya. Nilai keksaran yang paling kecil (permukaan yang halus) didapat pada cutter speed 250 rpm, feed rate 42,5 mm/menit dan dept of cut 1,5 mm.
