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.

Highlights

Abrasive water jet cutting (AWJC) is one of the unconventional machining processes that offers an alternative to other cutting technologies, finding its efficiency in high-precision machining of diverse and difficult-to-cut materials [1,2,3]
With the development of the aerospace and automotive industry, the abrasive water jet cutting process is introduced into various industrial applications to process complex and high-precision structures, such as hybrid composite materials [9], glass fiber reinforced with carbon fiber (CFRP) [10,11], titanium alloys [3,12], etc
The present paper proposes a new algorithm of calculation that allows the rapid determination of weld overlay material machinability with different hardness

Summary

Introduction

Abrasive water jet cutting (AWJC) is one of the unconventional machining processes that offers an alternative to other cutting technologies, finding its efficiency in high-precision machining of diverse and difficult-to-cut materials [1,2,3]. The abrasive water jet cutting process offers the possibility of processing materials in ecological conditions for sustainable development. Current research in the field of abrasive water jet cutting demonstrates the suitable use of a very thin waterjet stream for cutting high-performance materials. With the development of the aerospace and automotive industry, the abrasive water jet cutting process is introduced into various industrial applications to process complex and high-precision structures, such as hybrid composite materials [9], glass fiber reinforced with carbon fiber (CFRP) [10,11], titanium alloys [3,12], etc
