| 1 | Optimization of CNC cutting parameters using design of experiment(DOE) and desirability function显示文摘In this study,2~5 (five factors at two-level factorial design) design of experiment was applied to investigate a set of optimal machining parameters to achieve a minimum surface roughness value for Abies nordmanniana.Wood specimens were prepared using different values of spindle speed,feed rate,depth of cut,tool radius,and cutting directions.Average surface roughness (R_z) values were applied using a stylus.The objectives were to:(1)obtain the effective variables of wood surface roughness;(2) analyze which of these factors had an impact on variability in the CNC machining process;(3) evaluate the optimal cutting values within the range of different cutting levels of machining parameters.The results indicate that the design of experiment(DOE) based on the desirability function approach determined the optimal machining parameters successfully,leading to minimum R_a compared to the observed value.Minimum surface roughness values of tangential and radial cutting directions were 3.58 and 3.21 μm,respectively. | Ender Hazir Emine Seda Erdinler Kücük Hüseyin Koc | 2018 | Journal of Forestry Research2018，29，5： | 3 |
| 2 | First-principles study of the structural,elastic,electronic,optical,and vibrational properties of intermetallic Pd_2Ga显示文摘The structural,elastic,electronic,optical,and vibrational properties of the orthorhombic Pd2Ga compound are investigated using the norm-conserving pseudopotentials within the local density approximation in the frame of density functional theory.The calculated lattice parameters have been compared with the experimental values and found to be in good agreement with these results.The second-order elastic constants and the other relevant quantities,such as the Young's modulus,shear modulus,Poisson's ratio,anisotropy factor,sound velocity,and Debye temperature,have been calculated.It is shown that this compound is mechanically stable after analysing the calculated elastic constants.Furthermore,the real and imaginary parts of the dielectric function and the optical constants,such as the optical dielectric constant and the effective number of electrons per unit cell,are calculated and presented.The phonon dispersion curves are derived using the direct method.The present results demonstrate that this compound is dynamically stable. | Yildirim A Koc H Deligoz E | 2012 | Chinese Physics B2012，21，3： | 2 |
