“…Rega et al (2011) have experimentally studied the influence of processing gas on laser microdrilling and ablation of aluminum and stainless steel. Taguchi based Grey analysis can effectively recommend a method of optimization technique for determination of optimal parameter settings and effectively solve the complicated interrelationships among multiple quality characteristics, which are applied in different manufacturing, processes (Acherjee et al 2010). Some prior researchers attempted to find out the optimal process parameter settings for laser microdrilling process with less amount of HAZ (Heat affected zone), taper and recast layer.…”

“…The pulse length and power intensities along with surface temperatures affect the recoil pressure which plays a vital role in material removal in molten state. The level with the highest grey relational grade is considered as optimum process parameter level (Acherjee et al 2010). When the surface temperature exceeds a certain threshold value, plasma plume forms a shield over the machining area and reduces the energy available to the workpiece which has a harmful effect on machining operation.…”

Acrylate Polymers for Advanced Applications

Due to limitations of injection molding of polymer/plastic materials, complex plastic parts are often assembled from two or more injection-molded components. Joining of polymers can be achieved by chemical-based technologies and thermal methods such as welding. Welding technique is one of the important manufacturing routes that can be used to refine product design and reduce production cost. Plastic welding processes typically involve heating the joining faces to induce localized melting and subsequently applying pressure to cause molecular diffusion at the molten interface, which produces a solid weld upon cooling. The need for an effective welding process that is fast, accurate, and with no relative part movement has fueled the development of laser-transmission welding (LTW) technology. LTW is an innovative joining process for acrylate materials. The quality of weld highly depends on correct selection of process parameters in LTW. The systematic study and analysis are required to conduct LTE process economically and efficiently. In the present chapter, current prospects of applications of acrylates and joining of them using LTW has been analyzed. The main emphasis has been given to analyze the variations of quality performance characteristics with varying input welding factors and concluding remarks has been drawn from present work. From this study, it is observed that acrylics are future innovative industrial materials, which need to be joined to create complex features on them. Welding of acrylics using LTW to achieve better and more economical weld performance is still under continuous research by scientists/industrialists.

“…The generated heat is transported by thermal conduction into the top transparent part and also to the deeper layers of absorbing part. Consequently, both the parts melt at the joining interface, and a solid joint is formed as the melt layer solidifies [3]. After cooling and resolidification, a bond is formed at the weld seam [4].…”

Abstract-In present work laser transmission welding of polycarbonate is investigated and optimized using cuckoo search algorithm (CSA) incorporation with response surface methodology (RSM). Objectives are set to obtain higher weld strength as well as lower weld width to achieve better product quality. Parametric optimizations are carried out using CSA, in which the objective functions are developed using RSM. Results show that CSA gives comparatively better results than conventional optimization techniques. This is because of the fact that CSA can locate the global optima, as no parameters are held constant during the optimization process. This algorithm is also found to be capable of predicting accurate trends of the parametric effects of laser transmission welding of polycarbonate.
