There has been an increasing interest in the penetration of magnetic field-assisted machining processes in the industries. Due to the ease of contactless forces, magnetic fields have proved extremely versatile and relatively low cost when considering the potential increase in productivity of existing machining processes that it can provide. In this overview, we review the recent achievements and developments in magnetic field-assisted machining processes and their applications. A wide variety of machining domains are examined including electro-discharge machining (EDM), micro-EDM, electrochemical machining, magnetic-assisted machining and many more. The advantages and limitations of each implementation and potential future research pathways are also discussed.

PurposeThe objective is to carry out a thorough literature review and analysis of sustainable production system (SPS) and identify avenues for the future research.Design/methodology/approachA sample of 903 articles published from 1996 to 2019 in 40 journals were considered in the analysis. The classification and analysis of articles was done based on: time, focus area, methodology, research stream, authorship, industry sector, critical elements, implementation status, type of support and performance. Based on the analysis the future scope development needs are identified.FindingsThe findings are: increasing trend in empirical and conceptual research articles, need of sustainable principles implementation in the product development with combination of all the areas, need of more intercontinental research collaborations as the sustainable production is interconnected rather than isolated, need of sustainable constructs implementation as a coherent set instead of individual constructs, need of integration of sustainable philosophy with other manufacturing philosophies to achieve sustainable results and need of testing and validation of the support by researchers.Originality/valueThe results from the study will be useful to the researchers, academicians and professionals to trace the gaps, growth, pertinence and research developments in the field of SPS.

In the present scenario, metalworking fluids or cutting fluids are contributing a significant amount among the consumables used in the machining industry. Most of the industries use oil-based cutting fluids, which may cause skin and respiratoryrelated health issues to workers when they are exposed for longer hours. These limitations lead to developing non-oil-based novel cutting fluids to the industry. In this work, the biodegradability performance of newly developed cutting fluid was measured and compared with commonly used oil-based cutting fluid by the industries. Also, the performance of newly developed cutting fluid was investigated in the machining of AISI 420 stainless steel turbine blade material with an uncoated carbide tool. To circulate and recycle the developed cutting fluid at the machining zone, an experimental setup was developed. The developed cutting fluid performance was estimated over dry and oil-based cutting fluid environment conditions. The experiments were designed based on Taguchi L 27 orthogonal array while keeping the material removal rate as constant at 668 mm 3 s −1. The control factors were cutting environment, depth of cut, feed, and cutting speed. An optimal control parameter combination for minimal surface roughness of 0.31 μm, tool wear 18.7 μm, and temperature 178 °C was obtained. This study is expected to deliver a scientific path toward the novel development of non-oil-based cutting fluids for enhancing the machining quality and safety.
