Abstract

High Feed Machining (HFM) adalah salah satu teknik pemesinan yang semakin mendapatkan perhatian. Penerapan HFM diantaranya mampu diterapkan pada high feed milling yang bertujuan menghilangkan chip dalam waktu sesingkat mungkin menggunakan laju makan yang sangat tinggi. Faktor utama proses high feed milling yaitu kombinasi feed-per-tooth yang tinggi, dan depth of cut yang rendah. Berdasarkan latar belakang tersebut, penelitian ini menggunakan metode eksperimen dengan memvariasikan kedalaman potong radial, laju makan tinggi terhadap keausan pahat jenis HSS dan kekasan permukaan benda kerja Al6061, serta jarak atau persentase pengukuran. Variasi radial depth of cut sebesar 10%, 12.5%, dan 15% dari diameter pahat, sebesar 10 mm dengan flute berjumlah 2. Sementara feed rate yang digunakan sebesar 2808 mm/min, 2875 mm/min, dan 2942 mm/min. Kecepatan potong sebesar 150 m/min. Data eksperimen dilakukan analisa secara statistik melalui ANOVA dan regresi. FPT, RDOC, dan rentang Ap memiliki pengaruh yang signifikan pada keausan pahat dengan tingkat kepercayaan 5%. Pengaruh FPT sebesar 24.1%, RDOC sebesar 7.4%, dan rentang Ap sebesar 25.3% terhadap keausan pahat. FPT, RDOC, dan jarak dari collet memiliki pengaruh yang signifikan pada kekasaran permukaan dengan tingkat kepercayaan 5%. Pengaruh FPT sebesar 27.8%, RDOC sebesar 9.2%, dan jarak dari collet sebesar 35.9% terhadap kekasaran permukaan.

High Feed Machining (HFM) is one of the machining techniques that is gaining increasing attention. The application of HFM can be implemented in high feed milling, which aims to remove chips in the shortest possible time using a very high feed rate. The main factors in the high feed milling process are the combination of high feed-per-tooth and low depth of cut. Based on this background, this research uses the experimental method by varying the radial depth of cut, high feed rate against HSS type tool wear and Al6061 workpiece surface toughness, as well as the distance or percentage of measurement. The radial depth of cut variations were 10%, 12.5%, and 15% of the tool diameter, 10 mm with 2 flutes. The feed rates used were 2808 mm/min, 2875 mm/min, and 2942 mm/min. The cutting speed was 150 m/min. The experimental data was statistically analysed through ANOVA and regression. FPT, RDOC, and Ap percentage range have a significant influence on tool wear with a 5% confidence level. The effect of FPT was 24.1%, RDOC was 7.4%, and Ap range was 25.3% on tool wear. FPT, RDOC, and distance from the collet have a significant effect on surface roughness with a 5% confidence level. The effect of FPT is 27.8%, RDOC is 9.2%, and distance from the collet is 35.9% on surface roughness.
