In recent times, many commercial producers have taken steps to increase the efficiency, accuracy, and durability of their machining products. These steps involve increasing the quality of merchandise, lowering production value, and improving the manufacturing rate. These steps may be influenced by different factors like machining parameters, tool geometry, and the cloth of the painting’s piece. The turning process is influenced by input parameters as cutting speed, feed rate, depth of cut, cutting conditions etc. Therefore, the favored finish floor is normally targeted and the ideal strategies are selected to attain the specified first-rate. Generally, those models have a complicated courting among floor roughness and operational parameters, painting materials, and chip breaker sorts. Till now, many researchers have executed experimental investigations approximately the machining operations and evaluated the impact of machining parameters on the outputs of the manner; many researchers have tried to model the machining approaches by using diverse strategies like statistical, shrewd, and analytical techniques [1,2]. Maximum predictive fashions are able to estimate complicated relationships between machining input parameters and corresponding outputs [3,4].

The terminology of cutting fluids used in machining have bi-function use of reduction in friction between the cutting tool; for example, an end mill cutter and work job which is being worked over to make the product piece and reduce the temperature of the contact parts. However, there are operations such as drilling and turning that have a trifunctional effect of cutting fluid, i.e. cooling, waste chips removal and lubrication (Sharma et al. 2016). This gives us a perspective of what a salient part the cutting fluid plays in growing the output and efficiency of the machining operation industry. Generally, the cutting fluids which have been traditionally used by the machining industry in the past have raised environmental concerns and health hazards when used in excess quantities (Singh et al. 2017).
Turning Operations and Machines
Published in Zainul Huda, Machining Processes and Machines, 2020
In industrial practice, there are often machining requirements to produce cylindrical parts with complex geometric features that require multiple turning-related operations. Thus, during the machining process cycle, a variety of turning-related operations may be performed to the workpiece to yield the desired part of shape. These turning-related operations include straight turning, taper turning, facing, boring, contour turning, form turning, cut-off, grooving, external threading, internal threading, knurling, and the like (see Figure 5.2). External turning operations modify the outer diameter of the workpiece, while internal turning operations modify the inner diameter. Each type of turning operation is defined by the type of cutter used and the path of the cutter to remove material from the workpiece, as explained in the following paragraph.

In the turning process, the cutting fluids are used for improving the wear characteristics on the tool–work piece interface. The cutting fluids used need to take away the heat generated during the machining process and need to work as lubricant. A thin film needs to be formed between the tool–work piece interface to reduce friction and wear (Doll and Sharma 2011). The lubricant oils need to help in absorbing the heat formation during the machined process. With these properties, a less energy consumption can be achieved. In case of mineral-based lubrication, the workers get irritants and cause allergic reaction during the machining process. The fumes that are generated from the operation are harmful to the operators. A hygienic environment needs to be created for improved machining process.
Machinability analysis and application of response surface approach on CNC turning of LM6/SiCp composites

Nataraj and Balasubramanian stated that the aluminum MMC operational temperature had undesirable effect at higher than 350°C during which the alloy structure changes. However, if the temperature of the machined surface is below 350°C, the possibility of variation in microstructure and material properties are less.[6] In any turning process, factors such as machining velocity, feed, depth of cut, and tool geometric parameters including nose radius, rake angles played crucial role. Another exploration has been witnessed that the velocity of machining is the predominant variable for flank wear.[7] The roughness of the machined getting increased with an increase of cutting depth and for attaining improved surface finish, the velocity of cutting must maintained be as much as possible.[8]
A review on cryogenic treatment of tungsten carbide (WC-Co) tool material
Published in Materials and Manufacturing Processes, 2021
Turning is a single-point cutting tool operation wherein the tool remains stationary against a rotating workpiece. The machining dynamics involve a continuous metal removal process in which cutting and thermal loads are constantly transmitted to the tool which makes the process comparatively simpler and highly efficient. Literature studies (Table 4) show that turning is the most tested metal cutting application for comparing the performance of cryo-treated WC-Co tools.
