Mechanical machining processes are common manufacturing strategies to re-shape materials to desired specification. The mechanistic approach has revealed the mechanics of the machining processes with various parameters determined. The aim of this work is to investigate the impact of swept angle optimization and their influence on the specific cutting energy in milling AISI 1045 steel alloy. This...

In this paper a method is presented to generate uniform hexahedral meshes automatically. In this method, a solid model with complex geometry is decomposed into swept volumes with simpler geometry. A sweepable face on the solid model is selected as the generator face to generate a swept volume. Each generator face is specified with node density and a quadrilateral mesh is generated from it. Then...

In this study, we develop an ultra-fast fiber Bragg grating sensor system that is based on the Fourier domain mode-locked (FDML) swept laser. A FDML wavelength swept laser has many advantages compared to the conventional wavelength swept laser source, such as high-speed interrogation, narrow spectral sensitivity, and high phase stability. The newly developed FDML wavelength swept laser shows a ...

The sweeping algorithm is a classical algorithm that can generate high quality hexahedral meshes for swept volumes. However, the traditional sweeping algorithm can only generate single axis swept meshes. In order to expand the scope of the model that sweeping algorithms are applicable to, this paper proposes a global multi-axis swept mesh generation approach, which can robustly generate hexahed...

A polarization-maintaining buffered Fourier domain mode-locked (FDML) swept source with a center wavelength of 1300 nm is demonstrated. The scanning rate of the buffered FDML swept source is doubled without sacrificing the output power of the swept source by combining two orthogonally polarized outputs with a polarization beam combiner. The stability of the swept source is improved because the ...
