Sustainability in the manufacturing industry demands the optimization of machining processes to be both environmentally friendly and cost-effective. This research aims to analyze and predict surface roughness (Ra) in the milling process of AISI 1045 steel by integrating the Minimum Quantity Lubrication (MQL) method using vegetable oil-based nanofluids and Al2O3 nanoparticles. The use of vegetab…
This dissertation presents an in-depth investigation into the cryogenic machining performance of thin-walled Ti6Al4V (Ti64) alloy using carbon dioxide (CO₂) as a sustainable cooling medium. The research aims to improve surface quality while minimizing environmental impact by replacing conventional cutting fluids with cryogenic CO₂. Both uncoated and AlCrN-coated carbide end mills were used …
Proses pemesinan pada pembubutan menghasilkan deformasi plastis pada benda kerja. Deformasi plastis selama proses pemesinan terbentuk oleh adanya gesekan pahat potong terhadap benda kerja yang menghasilkan geram. Selama proses deformasi timbunya tegangan sisa pada permukaan yang dapat berpengaruh terhadap ketahanan lelah, kekuatan fraktur, dan ketahanan korosi. Kegagalan struktur dalam komponen…
