“…The chip underface confirmed that the diamond-coated insert performs the best among all the tool inserts. Recently the effect of cutting speed and surface chemistry of cutting tool for the dry turning of AA6005 aluminium alloy with regard to the formation of BUE has been studied [12]. They found that the CVD diamond coating WC-inserts which is inherently free of cobalt with improved rake surface finish has enormous potential in dry machining of AA6005 aluminium alloy.…”

Aluminium (Al) is the suitable material for aerospace and automotive industries due its light weight, corrosion resistance, weldability, non-magnetic and mechanical properties. But, machining of Al and its alloy and finding the suitable tool is really a big challenge because of its formation of BUE (Built-up Edge) and BUL (Built-up Layer). This paper presents the influence of cutting parameters (speed, feed and depth of cut) and its effect on the cutting force and the surface finish. Five different advanced cutting tool inserts (SPUN WC, SPGN WC, PCD, WC ? TiN and WC ? Ti(C, N) TiN ? Al 2 O 3 ) at different cutting speed (V c ) ranging between 300 m/min and 700 m/min and feed rate (f) of 0.045, 0.06, 0.09 and 0.125 mm/rev at a depth of cut of 0.2 mm (constant throughout the experiment) were taken for the experiment. Tool inserts were characterized by Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX) analysis. The cutting forces were measured using Kistler force dynamometer. Amongst all tools, PCD provided a better result in all aspects but surprisingly WC tool provided a better surface finish with lesser tool wear. For all cutting conditions, high speed (670 m/min) and low feed rate (0.045 mm/rev) were recommended. adhana(0123456789().,-volV)FT3 ](0123456789().,-volV)

“…Pengeluar mata alat pemotongan telah membangunkan gred mata alat karbida tidak bersalut dan bersalut yang boleh digunakan dalam pemesinan kering. Kesukaran utama dalam pemesinan aloi aluminium menggunakan karbida tidak bersalut terletak pada pembentukan kelebihan pasang siap (BUE) pada permukaan mata alat (Gangopadhyay et al 2010), ini disebabkan oleh suhu yang tinggi semasa pemesinan memudahkan aluminium lekat ke mata alat pemotong. Alat pemotongan bersalut yang sedia ada untuk pemotongan kering adalah bertujuan meningkatkan kekerasan mereka, menghalang bahan alat tersebut didedahkan dan mengurangkan pekali geseran (Rivero et al 2006& Shokrani et al 2012 dan ini dapat memanjangkan hayat mata alat pemotong.…”

Aloi aluminum menjadi tumpuan dalam aplikasi komponen automotif disebabkan sifatnya yang ringan yang dapat membantu mengurangkan penggunaan bahan api. Umum mengetahui bahawa komponen ringan yang diperbuat daripada tuangan aloi aluminium lebih kos efektif berbanding penggunaan tuangan besi untuk blok enjin, dan piston. Antara aloi aluminium yang mendapat perhatian pengkaji adalah berasaskan aloi Al-Si seperti aloi penuangan acuan dengan 9.5 wt.% Si (383), aloi penuangan pasir dengan 18.5 wt.% Si (A390) dan semburan aloi dibentuk dengan 25 wt.% Si (Al-25Si). Aloi A390 adalah sesuai untuk menggantikan komponen tuangan besi kerana kandungan silikon yang tinggi ini dapat mengurangkan pengembangan haba, dan ciri-ciri kakisan yang baik. Artikel ini membentangkan pemerhatian yang dilakukan terhadap mikrostruktur aloi aluminum A390 di bawah permukaan yang telah dimesin kisar. Parameter pemotongan yang dikaji ialah laju pemotongan 250-350 m/min, kadar suapan 0.02-0.04 mm/gigi, dan lebar radius 12.5 mm-25 mm. Manakala kedalaman paksi dimalarkan pada 0.3 mm. Pemesinan kisar dilakukan dalam keadaan kering dan kriogenik. Pemerhatian terhadap mikrostruktur mendapati terdapat kesan pemanasan pada laju pemotongan 350 m/min, kadar suapan 0.02 mm/gigi, lebar jejari 12.5 mm dalam keadaan pemotongan kering dengan mata alat yang telah haus. Manakala untuk parameter pemotongan yang lain tiada kesan pemanasan diperhatikan. Tiada sebarang perubahan mikrostruktur diperhatikan bagi julat parameter pemotongan yang dikaji. Ini menunjukkan, suhu pemotongan yang terjana adalah rendah dan tidak menyebabkan sebarang perubahan mikrostruktur bagi julat pemotongan kajian.

“…This is extremely challenging when dry machining is attempted [8]. Most hard coatings on tools like TiN, TiCN, TiAlN, and Al 2 O 3 have been reported to be susceptible to BUE and BUL formation in comparison with aluminium, although they are successfully used to machine a wide range of steels [9,10]. In this regard, diamond coating or polycrystalline diamond (PCD) have been found to be outstandingly capable of arresting BUE formation [11,12].…”

In the present paper, a graphite-PTFE composite coating (Gr-x) on an HSS end mill is proposed for machining aluminium. The suitability of this coating was first simulated in a pin-on-disc test and was compared to the performance of MoS 2 before evaluation through machining testing. In the tribo-test, both coatings exhibited their extraordinary lubrication properties and could successfully reduce uneven frictional forces as observed with an aluminium pin against uncoated HSS. However, MoS 2 -coated HSS end mills failed to produce such a favorable impact in machining. SEM images and chip morphology indicate evidence of the adherence of aluminium on the rake surface of a MoS 2 -coated tool. In contrast, Gr-x coating substantially outperformed MoS 2 in the end milling test. Built-up edge (BUE) was completely arrested by Gr-x coating, and a better finish resulted from reduction of cutting force. Under the given machining conditions, the temperature was expectedly below the chemical degradation point of both coating materials and hence environmental humidity seemed to be a critical factor, which weakened the performance of MoS 2 but improved that of graphite. Cutting speeds no higher than 60 m/min are recommended for Gr-x coating during end milling of aluminium.
