Abstract
Purpose
The purpose of this paper is to provide a practical review of metal working fluids and their implications to the machining practice. Despite their widespread use and applications, there are several scientific and economic factors that call for an investigation of current practices and development of new approaches.
Design/methodology/approach
There are numerous methods that diverge from traditional “wet” machining, which move towards an environmentally friendly and cost effective machining process. This includes looking at both minimum quantity lubrication and dry machining as methods to reduce recurring costs, lower health care premiums associated to metalworking fluid exposure, and to minimize the environmental footprint attributed to machining.
Findings
Traditional machine lubrication techniques are in use today despite a lack of scientific or economic evidence that they function efficiently. Depending on the machine type and material used, there are several possible methods that can minimize or eliminate metalworking fluids from the machining process.
Practical implications
This paper provides a practical assessment of current industrial practices and offers opportunities for improvement from both an economic and an environmental perspective.
Originality/value
This paper provides an overview of previously conducted research to suggest areas of improvement in manufacturing processes utilizing metalworking fluids.

Abstract
Purpose
This paper aims to formulate a new metal working fluid (MWF) composition including some eco-friendly emulsifiers, corrosion inhibitor, biocide, and non- edible vegetable oil (castor oil) as the base oil. To achieve this aim, five MWFs with different hydrophilic–lipophilic balance (HLB) value as 10, 9.5, 9, 8.5 and 8 were prepared to identify the optimum HLB value that gives a highly stable oil-in-water emulsion. The performance of castor oil based MWF was evaluated using tool chip tribometer and drill dynamometer. The surface morphology of steel disc and friction pin was performed using scanning electron microscope (SEM) and 3D profilometer. The results revealed that the use of the prepared cutting fluid (E1) caused the cutting force to decrease from 500 N for dry high-speed steel sample to 280N, while the same value for a commercial cutting fluid (COM) was recorded as 340 N at drilling speed and cutting feed force as 1120 rpm and 4 mm/min., respectively.
Design/methodology/approach
A castor oil-based metalworking fluid was prepared using nonionic surfactants. The composition of the metalworking fluid was further optimized by adding performance-enhancing additives. The performance of castor oil based MWF was analyzed using Tool chip tribometer and Drill dynamometer. The surface morphology of steel ball and a disc was done using 3D profilometer and SEM.
Findings
Studies revealed that castor oil-based MWF having Monoethanolamine (MEA) as corrosion inhibitor was found to be highly stable. The drilling dynamometer and tool chip tribometer studies showed that castor oil-based MWF performance was comparable to that of commercial MWF.
Research limitations/implications
This study aims to explore the performance of the castor oil based metalworking fluid (MWF) using tool chip tribometer and drill dynamometer.
Practical implications
The conventional MWFs are petroleum derives and are unsustainable. Use of non-edible plant-based oils for preparing the MWF will not only be conserved environment but also add value addition to agricultural crops.
Social implications
The social Implications is aiming to decrease the environmental impact that results from the using of mineral cutting fluids.
Originality/value
The originality of this work is to replace the mineral oil and synthetic oil based cutting fluids with more eco-friendly alternatives one. In addition, the investigation will focus on developing functional additives required for cutting fluids which are environmentally benign.
