Abstract

Abrasive water jet machining (AWJM) is known for precise cutting of metals and nonmetals. In the past few years, this machining technology has undergone some important developments which possibly enhanced its capability and extended its applications. This article presents such important developments and related attempts on AWJM made by researchers in the recent past. The scope covers AWJM of important nonmetallic materials like rock, glass, rubber, composites and ceramics etc. The important developments have been in the form of utilizing abrasives like sugar particles, glass beads, ice particles, bone powder; water-less abrasive jet machining; process optimization; and acoustic emission monitoring etc. that enhanced the capability of the AWJM process towards cost reduction, quality enhancement, and sustainability. The article intends to amass such important information related to the recent developments in AWJM for nonmetal cutting and aims to facilitate scholars and researchers with this new knowledge.

Abstract

Hybrid machining processes (HMP) have been developed to double the benefits of advanced or conventional machining processes by combining them. The challenges that occur in machining of intricate shapes and features, micromachining, and machining of very hard and soft materials can be overcome by HMPs. Assistance from external sources like vibrations, abrasives, and magnetic fields can facilitate material removal and enhance machining efficiency. This paper analyses some important recent research and innovations carried out in the domain of vibration-assisted HMPs and presents them to enrich the knowledge of scholars and researchers to establish the field further. The major focus of the article is to highlight the role of vibration assistance in facilitating both conventional and modern machining domains specifically covering electrochemical machining, electric discharge machining, turning, and their variants. Industry 4.0 and Sustainability-oriented innovations in advancing HMPs, involving leveraging digital technologies to enhance productivity while minimizing environmental impact, have also been featured

Abstract

Embedding Sustainable Development Goals (SDGs) into engineering education is critical to prepare engineers who are both technically skilled and socially responsible. Universities and nations are increasingly evaluated by their contributions toward SDGs, making sustainability a central element of modern curricula. Integrating sustainability not only fosters economic growth, environmental protection, and social impact but also encourages learners to balance technical excellence with societal welfare. Quality education, as emphasized in SDG 4, is achieved when engineering programs move beyond technical training to encourage values of responsibility, ethics, and sustainability in future engineers. Sustainability-integrated engineering curricula require awareness, knowledge-building, involvement, and collaboration attempts. This article covers some important aspects of embedding sustainability in engineering education. With the help of showcasing the activities on sustainability-integrated teaching, learning, and projects, conducted at one of the leading international Pan African universities, this article aims to disseminate the concept of sustainable engineering education and encourages future interventions to establish the field further.
