Prediction of Surface Roughness and Optimization of Machining Parameters in Drilling Process of Aluminum Alloy Al6061
In this paper, an experimental research was conducted to investigate the influence of the tool diameter, spindle speed, and feed rate on the surface roughness in hole drilling process. The Box Behken experimental matrix that was used with 15 experiments. The Minitab 16 software was used to evaluate the experimental results. The analyzed results showed […]

The materials selected for each part, the reason for selecting that material and the design of the different parts of the shock absorber compressor spring was carried out. The manufacturing processes […]
Design and Evaluation of Ankle Reconstruction
Ankle reconstruction is a fairly new concept and is one of the popular treatment for ankle fractures and arthritis. Ankle reconstruction aims to offer a successful alternative to arthrodesis, the existing mainstay and gold standard surgical procedure for disabling ankle arthritis. The surgeon fits the talus bone of the upper foot and the tibia bone […]
Design Evaluation and Development of Lumbar Cage
Lumbar spinal fusion is advance method of surgery to permanently join or fuse two or more vertebrae in the human spine in order to eliminate the relative motion between them. It is currently considered as the most successful surgery in the patients with spinal deformity and degenerative spondylolisthesis. Its success critically depends on the geometric […]
Effects of Al2O3 Cu Water Hybrid Nanofluid on Heat Transfer of Double Pipe Heat Exchanger using CFD
The researchers have consistently observed higher heat transfer rates with different kinds of nanofluids among others, Al2O3, Cu, CuO, Fe3O4, Fe2O3, CNT, nickel, Nano diamond, TiO2, and SiO2 flow in a tube under laminar or turbulent flow conditions. The heat transfer enhancement of nanofluids depends on particle concentrations, thermal conductivity of nanoparticles and mass flow […]
