The aim of this paper is to review the literature on the prediction of cutting tool life. Tool life is typically estimated by predicting the time to reach the threshold flank wear width. The cutting tool is a crucial component in any machining process, and its failure affects the manufacturing process adversely. The prediction of cutting tool life by considering several factors that affect tool life is crucial to managing quality, cost, availability and waste in machining processes.

This study has undertaken the critical analysis and summarisation of various techniques used in the literature for predicting the life or remaining useful life (RUL) of the cutting tool through monitoring the tool wear, primarily flank wear. The experimental setups that comprise diversified machining processes, including turning, milling, drilling, boring and slotting, are covered in this review.

Cutting tool life is a stochastic variable. Tool failure depends on various factors, including the type and material of the cutting tool, work material, cutting conditions and machine tool. Thus, the life of the cutting tool for a particular experimental setup must be modelled by considering the cutting parameters.

This submission discusses tool life prediction comprehensively, from monitoring tool wear, primarily flank wear, to modelling tool life, and this type of comprehensive review on cutting tool life prediction has not been reported in the literature till now. The future suggestions provided in this review are expected to provide avenues to solve the unexplored challenges in this field.

Through its transnational networks, the Asian diaspora builds a bridge between the nations of origin and the host countries, greatly contributing to growth. To advance development initiatives in Asia and elsewhere, it is imperative to acknowledge the potential and complexity of these networks. The purpose of this study is to investigate how Asian diaspora-created transnational networks contribute to development outcomes. It aims to comprehend the ways in which these networks impact the social, cultural and economic development of both the host and home countries. The economic, social and cultural contributions made by the Asian diaspora and their international networks are evaluated in this study in relation to development.

The existing literature review emphasises the diverse role of the Asian diaspora in development, including remittances, investment, knowledge transfer and cultural exchange.

It recognises the potential of diaspora engagement in development projects, but there are still gaps in understanding the dynamics of transnational networks and their influence on development outcomes. This study aims to uncover the complex ways in which the global networks of the Asian diaspora contribute to development. Identifying the factors that help or hinder their effectiveness will provide policymakers and development practitioners with insights to harness these networks for sustainable progress.

Understanding the networks will have significant ramifications for both the host and home nations. It will highlight the significance of transnational connections in fostering economic, social and cultural development in Asia and how crucial it is to use the Asian diaspora’s transnational networks to their full potential in the larger conversation about connection and global development.
