ssss1, the last chapter of ssss1, discusses in detail reinforcing, performance analysis, processing and characterization of various methods of polymer welding, i.e. laser welding, infrared welding, spin welding, stir welding, and vibration welding. This chapter also covers various alloys of aluminum for lightweight applications and the current status of polymer composite applications in industries and future prospects. This chapter highlights the complications related to fusion, heat transfer and joint strength, as well as their solutions with the future prospect of polymer welding empowering polymers to be an absolute substitute for metal, which can be achieved by understanding the concept of dissimilar welding for joining polymer composites with metals and their controlling factors, and by selecting an appropriate welding process for various types of polymers.

ssss1, the first chapter of ssss1, provides the reader with an idea of fabrication and a description of the processing techniques of natural-based composites for light body vehicle applications. In doing so, the genetic equation for modeling tool flank wear is developed using experimentally measured flank wear values and genetic programming. Using these results, the genetic model presenting the connection between cutting parameters and tool flank wear is extracted. Then, based on a defined machining performance index and the obtained genetic equation, optimum cutting parameters are determined. This chapter concludes that the proposed modeling and optimization methodology offer the optimum cutting parameters and can be implemented in real industrial applications.
