Optimization of Cutting Parameters and Analysis of Effects of Artificial Aging on Machinability of AA7075 Alloy

Abstract: Bu çalışmada, AA7075 alüminyum alaşımında yaşlandırma ısıl işleminin işlenebilirliğe etkisi araştırılmıştır. Ticari olarak T6 ısıl işlem şartlarında temin edilen ana malzeme ve yaşlandırılan malzeme üzerinde tornalama deneyleri yapılarak, kesici takım uç yarıçapının ve kesme parametrelerinin yüzey pürüzlülüğü üzerindeki etkileri araştırılmıştır. İşleme şartları Taguchi yöntemine göre L18 dizininde tasarlanmıştır. İşleme deneyleri kuru kesme şartlarında CNC torna tezgâhında gerçekleştirilmiştir. Yüzey pürüzlülü… Show more

“…The Ra values generally decrease with increasing Vc (m/ min). This situation in many studies has been associated with the decrease in the tendency of built-up edge (BUE) formation [13][14][15][16][17]. The surface roughness is approximately 30% decrease with increasing cutting speed from 90 to 120 mm/rev while 37% decrease by feed rate from 120 to 150 mm/rev in turning tests using as-received inserts.…”

“…There are many factors that have an influence upon product cost and quality; for example, rigidity of machine tool, the workpiece and tool materials, machining parameters, cooling etc. Therefore, numerous researchers recommend that the cutting simulation and optimization of input parameters is necessary to reduce the production cost and machining time [7][8][9][10][11][12][13][14][15]. Yaşar [16] investigated the thrust force modelling by using Advantedge software and optimization of Ra in drilling of AA-7075.…”
