Abstract

This study aims to evaluate the effect of feed rate (advance speed) on the wear of Creusabro 4800 saw blades during the cutting of low-carbon steel using a cold saw machine with a constant cutting speed of 107 m/s. The methods employed include literature review, direct field observation, interviews with technicians and operators, and data analysis from operational logbooks over a 40-day period. The results show that increasing the advance speed significantly accelerates tooth wear, reduces the number of cuts that can be performed, and affects the quality of the cut surface. An advance speed of 0.05 m/s produced 1200 cuts with 0.20 mm wear, while at 0.40 m/s, wear increased to 1.00 mm and the number of cuts dropped sharply to 300 units. Observed wear patterns included flank wear, rounding, and chipping, which were aggravated by thermal load and cyclic pressure due to the geometry of materials such as H-beams and C-channels. The optimal advance speed range was found between 0.10–0.20 m/s, where the number of cuts remained high and wear was within acceptable limits. This study recommends implementing a blade replacement logbook system, using active cooling systems, and evaluating the use of TCT blades as an alternative to improve cutting efficiency and tool life in industrial production settings

Abstract

Proses pemotongan menggunakan mesin cold saw memegang peranan penting dalam industri fabrikasi baja karena memengaruhi produktivitas dan efisiensi penggunaan alat potong. Penelitian ini bertujuan untuk menganalisis hubungan antara kecepatan pemajuan (advance speed) dan jumlah potongan yang dihasilkan oleh saw blade pada mesin cold saw di PT XYZ. Penelitian menggunakan pendekatan deskriptif kuantitatif dengan metode studi pustaka, observasi lapangan, wawancara, dan analisis data logbook operasional mesin selama 40 hari kerja. Data yang dianalisis meliputi variasi advance speed dan jumlah potongan yang dihasilkan oleh saw blade pada kecepatan potong konstan sebesar 107 m/min. Hasil penelitian menunjukkan bahwa peningkatan advance speed berkaitan dengan penurunan jumlah potongan yang dapat dihasilkan oleh saw blade. Pada advance speed 0,05 m/s diperoleh jumlah potongan tertinggi sebesar 1200 unit diperoleh jumlah potongan tertinggi sebesar 1200 unit, sedangkan pada advance speed 0,40 m/s jumlah potongan menurun menjadi 300 unit. Rentang advance speed 0,10–0,20 m/s menunjukkan jumlah potongan yang relatif tinggi, yaitu antara 750–1000 potongan per blade, dibandingkan dengan advance speed 0,30–0,40 m/s yang menghasilkan 300–500 potongan per blade. Hasil penelitian menunjukkan bahwa pengaturan advance speed yang tepat dapat meningkatkan efisiensi penggunaan saw blade serta mendukung penerapan sistem penggantian blade yang lebih terukur berdasarkan data operasional.
