Optimization Method of Abrasive Water Jet Cutting of Welded Overlay Materials

Abstract

The great advantages of abrasive water jet cutting (AWJC) led to a rapid development of technology. The necessity of studying the process for different materials with weld overlay layers appeared due to the more widespread use of the process of jet cutting. Also, weld overlay is used widely in order to increase the durability of products used in the automotive industry. The complexity of shape, surface integrity, rapid processing, easy programming, low costs, and large flexibility of AWJC technology depends on the optimization of functional parameters and correct setting of machinability of cutting materials is one of the most important. A method of optimizing the process is the correct identification of machinability of welded workpieces with different hardness in layers. This research presents the new method and the experiments that validate the theoretical modeling. Average difference between the theoretical and the experimental values of machinability is small and lead to accuracy of results and demonstrates that this method can be used in practice.
