Politeknik Dergisi, 2017; 20 (4) : 743-751 Journal of Polytechnic, 2017; 20 (4) Investgation of Effects of The Aging Methods Applied on Aa2024 Aluminum Alloys on Machinability With Taguchi ond Anova ABSTRACTIn this study, machinability tests were executed. AA2024 aluminum alloy that are used in field of automotive and aero industries widely was preferred material in the experimental works. Effects of aging methods that were applied to AA2024 aluminum alloy on machinability were investigated. Test specimens obtained from T3 and T6 that are used methods for aging of AA20024 aluminum alloy, were machined with various cutting parameters (V: 150 m/min, 200 m/min, 250 m/min; F: 0.1 mm/tooth, 0.2 mm/tooth, 0.4 mm/tooth). The test specimens were machined on a CNC milling machine by using the L18 mixed model of Taguchi. Cutting forces (Fx, Fy, Fz) and surface roughness (Ra) were measured. Analysis of Taguchi and ANOVA were done for the results of test. The results showed that main effect factors of the cutting forces and surface roughness were federate and cutting speed. In addition, it was seen that the aging types caused a little effect on the cutting forces and surface roughness. It was determined that the T3 for cutting forces and T6 for surface roughness were very well.

Investigation of the Effect of U Drills with Different Properties on Thrust Force, Torque and Spindle Load

“…Thus, it was stated that the spindle rotates and there is a loss of information while sensing and capturing the power (spindle load) due to the damping effect of the spindle rotor caused by inertia, and chip clogging in the drill flutes may cause a change in the power data [11]. In another study, it has been suggested that the spindle load information changes randomly because the low-frequency changes in drilling torque due to chips stuck in the hole cannot be captured by the spindle load signal [1]. Due to the aforementioned conditions, the spindle load R 2 value is considered to be relatively low compared to Fz and Mz.…”

“…The material AA2024-T351 is an aluminum alloy that has undergone an aging process. It is used in various industries, especially in aviation [1]. As is known, aluminum alloys have high adhesion/smearing rates.…”

Yüksek Hızlı Oksi-Yakıt (HVOF)Yöntemiyle Kaplanmış Çelik ve Alüminyum Alaşımlarının Aşınma Özelliklerinin Taguchi Metoduyla Optimizasyonu

“…Varyans analizi (ANOVA) girdiler ve çıktılar arasında olası ilişki şiddetinin belirlenmesinde kullanılan bir yöntemdir. Deneysel çalışmalarda sonuçların yorumlanmasında en önemli nokta deneylerde kullanılan işlem parametreleri ile deney sonrası elde edilen sonuçlar arasındaki ilişkinin belirlenmesidir [28].…”

Effect of Anodic Oxidation on Tribological Behavior of 2017A Alloy

“…Different types of electrolytes and anodizing processes are used according to the place of use of aluminum and the alloy type of aluminum used. Aluminum alloys are used in many different fields such as automotive and aerospace due to their superior properties [2,[6][7][8][9][10][11][12]. In addition to many superior properties (such as high corrosion resistance, light weight), weak tribological and interfacial mechanical properties also create some disadvantages [14].…”
