Abstract: Bu çalışmada, hafif yapı metallerinde minimum miktarda yağlama (MMY) sistemi altındaki işlenebilirliği ile ilgili çalışmalar araştırılmıştır. Hafif metal ve alaşımlarının, işlenebilirliği son derece zor ve maliyetli malzemelerdir. Yapılan çalışmanın temel amacı, bu alanda yapılacak bilimsel çalışmalara katkı yapmak ve aynı zamanda hafif metaller ve alaşımlarının işlenmesi sırasında doğru kesici takım, işleme operasyonu ve kesme parametrelerinin seçimine yardımcı olmaktır. Çalışmanın bir diğer amacı ise MMY sis… Show more

In the die-molding industry, milling steels in a hardened condition is common. Tool wear and cutting-forces occurring during this process must be considered for better surface quality. The cutting performance of nano-layered AlTiN/TiN coated carbide cutting-tools in AISI D2 face-milling was evaluated in this work. Single-layer hard-coated carbide cutting-tools and uncoated cutting-tools were used to compare cutting performance testing. All cutting-speeds nano-layer AlTiN/TiN coated carbide cutting tool presented longer cutting-length than TiAlN and TiN coated ones and uncoated tool. Notch wear is an overriding wear mechanism, followed by build-up edge formation for all cutting-tools. Using a nano-layer AlTiN / TiN hard-coating, cutting-force values were lowered in all experiments.

In machining processes, MQL method is substantially preferred in terms of sustainable production because of lower usage of cutting fluid and better cutting performance in comparison with traditional techniques. On the other hand, it is also critical that the cutting fluid used is not hazardous to human and environmental health. In the present study, we aimed to investigate the cutting performance of AISI O2 steel in the presence of the cutting fluid containing various amounts of environmentally friendly Nano hexagonal boron nitride (Nano h-BN) based ethylene glycol (EG) by minimum quantity lubrication (MQL) method. Nano h-BN at 1% and 2% percentage by volume was added to the ethylene glycol and sonication was carried out for one hour for both prepared cutting fluids. Based on the experimental results using prepared cutting fluids, the highest cutting tool life was obtained in tests using 2% h-BN containing cutting fluid with 2.4 m cutting length. The improvement in tool life was approximately 46% using 2% h-BN containing cutting fluid compared to using 1% h-BN containing cutting fluid in milling tests. 2% h-BN containing cutting fluid compared to dry conditions in terms of tool life, the increase was approximately 78%. The improvement in surface roughness value measured on milled surface of workpiece material was approximately 60% using 2% h-BN containing cutting fluid compared to dry conditions. Compared to using 1% h-BN containing cutting fluid the improvement in surface roughness values was approximately 46%. A reduction in the cutting forces measured by the increased h-BN ratio in the prepared ethylene glycol based cutting fluid has occurred. As a result of SEM images and EDS analysis of worn tools, it was observed that the dominant wear mechanism was abrasion in all applied tests.
