Investigation of variation in tool-chip contact length in orthogonal cutting process

The tool-chip contact length has an important effect in view of tool life and tool wear in machining process. An increase in tool-chip contact length may results in a decrease of tool life. Besides the tool-chip contact length is an important element in formation of crater wear. The increasing of tool-chip contact length results in increase of friction forces acting on tool rake face and affects the temperature distributions along the cutting tool. First, in this study, all analytical models proposed to calculate the tool-chip contact length were compared with each other. Second, the tool-chip contact length was calculated using three different models for different workpiece materials and cutting parameters. The experiments were performed in a series of test in order to understand the relationship between tool-chip contact length and cutting velocity, material type and undeformed chip thickness.Takım-talaş temas boyu, işleme prosesinde takım ömrü ve takım aşınması açısından önemli bir etkiye sahiptir. Takım-talaş temas boyundaki artış takım ömrünün azalmasına neden olabilir. Ayrıca takım-talaş temas boyu, krater aşınma davranışının önemli bir unsurudur. Takım-talaş temas boyunun artması, takım talaş yüzeyinde sürtünme kuvvetlerin artmasına neden olmakta ve kesici takım boyunca oluşan sıcaklık dağılımını etkilemektedir. Öncelikle bu çalışmada takım-talaş temas boyunun hesaplanması için kullanılan bütün analitik modeller birbirleriyle karşılaştırılmıştır. Daha sonra takım-talaş temas boyu, farklı iş parçası malzemesi ve kesme parametreleri için üç farklı model kullanılarak hesaplanmıştır. Takım-talaş temas boyu ile kesme hızı, malzeme tipi ve deforme olmamış talaş kalınlığı arasındaki ilişkinin anlaşılması için tornada bir seri deney yapılmıştır. Tornalama işlemleri ortagonal kesme koşulları altında ve seramik kesici takım kullanılarak gerçekleştirilmiştir. Elde edilen sonuçlara göre, artan ilerleme değeri ve malzeme türü takım talaş boyunu önemli oranda etkilemektedir

FT-IR and Raman vibrational analysis, B3LYP and M06-2X simulations of 4-bromomethyl-6-tert-butyl-2H-chromen-2-one

In this study, the experimental and theoretical vibrational frequencies of a newly synthesized bacteriostatic and anti-tumor molecule namely, 4-bromomethyl-6-tert-butyl-2H-chromen-2-one have been investigated. The experimental FT-IR (4000-400 cm- 1) and Raman spectra (4000-100 cm- 1) of the compound in solid phase have been recorded. The theoretical vibrational frequencies and optimized geometric parameters have been calculated using density functional theory (DFT/B3LYP: Becke, 3-parameter, Lee-Yang-Parr and DFT/M06-2X: highly parametrized, empirical exchange correlation function) with 6-311++G(d, p) basis set by Gaussian 03 software, for the first time. The assignments of the vibrational frequencies have been done by potential energy distribution (PED) analysis using VEDA 4 software. The theoretical optimized geometric parameters and vibrational frequencies have been found to be in good agreement with the corresponding experimental data and results in the literature. In addition, the highest occupied molecular orbital (HOMO) energy, the lowest unoccupied molecular orbital (LUMO) energy and the other related molecular energy values of the compound have been investigated using the same theoretical calculations. © 2014 Elsevier B.V.

Protocol for tool wear measurement in micro-milling

Micro-milling yields small accurate parts quickly for electromechanical, aerospace, and medical applications. Due to their small size, micro-tools wear quickly and unpredictably therefore tool wear is difficult to measure and is poorly understood, leading to excessive tool changes and reduced productivity. This paper, therefore, proposes a new protocol for micro-tool wear measurement to overcome these problems. A strict set of criteria as found in an ISO standard is impractical for micro-milling research. The method herein allows comparisons to be made across materials and situations and detailed are certain criteria that must be fulfilled to achieve this. To evaluate the protocol micro-tools were used to machine three materials: brass, titanium and Hastelloy; and wear curves produced. Using the described protocol, these wear curves can be analysed similarly to those for larger tools. Profile analysis of the slots machined provides valuable information about tool wear where direct measurement is impossible. This new protocol presents a novel method for analysing and reporting tool wear for micro-end-mills, allowing them to be compared under different machining conditions and/or milling different materials, something not afforded by existing machining standards. The information can then be transferred to industrial applications, extending tool life and improving process efficiency
