Machining Characteristics

Presently surface microtexturing has found many promising applications in the fields of tribology, biomedical engineering, metal cutting, and other functional or topographical surfaces. Most of these applications are material-specific, which necessitates the need for a texturing and machining process that surpasses the limitations posed by a certain class of materials that are difficult to process by laser ablation, owing to their optical or other surface or bulk characteristics. Laser induced plasma micromachining (LIPMM) has emerged as a promising alternative to direct laser ablation for micromachining and microtexturing, which offers superior machining characteristics while preserving the resolution, accuracy and tool-less nature of laser ablation. This study is aimed at understanding the capability of LIPMM process to address some of the issues faced by pulsed laser ablation in material processing. This paper experimentally demonstrates machining of optically transmissive, reflective, and rough surface materials using LIPMM. Apart from this, the study includes machining of conventional metals (nickel and titanium) and polymer (polyimide), to demonstrate higher obtainable depth and reduced heat-affected distortion around microfeatures machined by LIPMM, as compared to laser ablation.

In this work, we analyze the effects of S doping on the structural and optical characteristics of pure cadmium oxide (CdO) filmsat varying concentrations of CdO1−x:Sx(X=0.2, 0.4, and 0.6), Sulfur is a chemical element with the atomic number 16 and the symbol S. The films were created using a laser-induced plasma (LIP) with a wavelength of 1064 nm and a duration of 9 ns at a pressure of 2.5×10−2mbar.X-ray diffraction studies revealed that all of the produced films are polycrystalline. The topography of the film's surface was evaluated using AFM, and the findings revealed that as the amount of doping increases, so does the grain size, along with an increase in the average roughness. The absorbance spectrum of the wavelength range (350-1100) nm was used to investigate the optical characteristics of all films. This rise might be the so-called Borsstein-Moss displacement has been viewed as a result of this. because the lowest layers of the conduction beams are densely packed with Because electrons require more energy to move, it seems as though the energy disparity widens.
