Thesis on laser cutting

Oxygen gas pressure also has a remarkable effect on the cut edge roughness. It is found that as the gas pressure increases, the roughness is increased. Increasing of the cutting speed gives the narrower average kerf width and the smoother cut surface. Save to Library. Orthogonal array based experimental data were trained by Artificial Neural Network ANN for the modelling of laser cutting process of Perspex sheet. The simulation results were compared with factorial design experimental observations The simulation results were compared with factorial design experimental observations.

The factorial design is selected for estimation of error on each dataset of observation table with missing values.

Laser cutting: influence on morphological and physicochemical properties of polyhydroxybutyrate.

The ANN simulation evaluation results are expected to depict better generalization based on very small training datasets by applying feed forward back-propagation. The study shows the benefits and disadvantages of neural network parameters variation. The increment in size of training datasets based on factorial design generate better accuracy in simulations as compared to orthogonal array modelling. The research concludes that ANN modelling can be utilized by the new researcher without much trouble from the missing values in observation tables.

Fashion conscious consumers demand updated and up style look for themselves. They not only look at the functions of the product but also the aesthetics according to the current fashion. They are now more conscious of what they buy, about They are now more conscious of what they buy, about the style, visual appearance, etc. The use of faux leather instead of natural leather can cater the demand of fashion products as well as will also take care of the environmental, economic and religious concerns of the consumers.

This research is on the utilization of faux leather as the design element for the apparels. Using different techniques, innovative designs collection is developed. Further, the selected techniques have been applied as the surface enhancement on Indo-western outfits. Creatures like alligators, ostriches, and kangaroos are slaughtered in China, which exports skin all over the world.

Most of the leather comes from developing countries, for example, China and India, where animal welfare regulations are possibly non-existent or not reinforced strictly. In India, a PETA study discovered that workers break cows " tails and apply tobacco, chili peppers to their eyes in order to force them to get up and walk after they collapse from fatigue on the way to the slaughterhouse.

    The leather is not environment-friendly, as it is responsible for all ecological destruction caused because of the beef industry in addition to the pollution due to the toxins found in tanning. It is very difficult to launder leather because of poor resistance to watermarks after laundering. Leather has weak resistance to mildew formation. Hence, the end products require frequent maintenance treatments. Its natural origin makes it unsuitable for the mass production system, as it is very difficult to obtain consistent quality. Also, deliberate animal killing is associated with natural leather. It is of major concern due to decreasing population of these animals. Animal skin is turned into finished leather through the use of dangerous mineral salts, formaldehyde, coal-tar derivatives, cyanide-based oils and dyes, chrome, and other toxins.

    People who work in and live near tanneries die of cancer caused by exposure to toxic chemicals used to process and dye of leather [3]. Faux is a French word that means fake, or not real. Faux leather is used when the use of real leather is too expensive or unsuitable or even unethical. Faux leather was created in the early years of the twentieth century, but it was very rigid and had an unpleasant smell. The major problem of past faux leather was that it was not breathable. This meant that wearing faux leather would leave a nasty smell and a nasty feeling. In the sixties, a company called DuPont invented a new way of manufacturing faux leather, by added tiny holes in faux leather, with the use of a new technique [4].

    For many people, the thought of wearing animal skin is just unacceptable, that is why there are many brands that specialize in making faux leather clothing and accessories. Real leather is costly as compared to faux leather and more difficult to work than faux leather [5].

    In addition to the variety of materials that are processed in FabLabs, universities or schools, even the finest geometries can be produced with the highest precision. Laser cutting gives users complete freedom for developing and implementing ideas. Quite the opposite. In addition, a lock mode for laser parameters can be adjusted so that predefined parameters from the material database can not be changed retrospectively.

    Thus, all users find the same initial situation at any time.
