“…These authors reported strong associations between chatter suppression and surface integrity of the work material. While tool vibration was the focus of some studies, including Singh et al (2018), Lawrance et al (2020a), Prabhu et al (2020), Biju andShunmugam (2019), Saleh et al (2021) and Yavaraju and Nanda (2018), several other studies analyzed vibration of the work material (Venkata rao et al, 2013(Venkata rao et al, , 2014. However, in both cases, their results failed to reveal a ranking according to a common scale to guide resource distribution during the boring process.…”

In boring E250 B0 steel material, the selection of process parameters is one of the most challenging tasks to achieve. The boring literature lacks understanding and fails to reveal how to select the important boring parameters for utmost resource distribution to the most important parameters. This article proposes a novel method to analyse the importance of parameters in boring to produce utmost surface roughness using the entropy-decision tree-VIKOR approach as a multi-criteria decision-making solution to the choice of process materials for superior surface roughness. The choice parameters include speed, depth of cut, feed and nose radius. The entropy approach was instituted to attain the weight of the diverse parameters. The decision tree approach is deployed through the classification of the parameters as beneficial and non-beneficial and the expected values at each mode evaluated. The desirable weightage is then established and serves as the input to the VIKOR approach. This converts the desirable weightage into unit measures through the best/worst value and weightage evaluation. The individual regrets are then analyzed and the final ranking obtained. Results revealed that the depth of cut is the most important parameter, then nose radius (0.98), feed (0.307) and speed (0), respectively. Therefore, a plan to assign more measures to the depth of cut may be developed and the least resources may be assigned to speed. This detail may be helpful to prepare the annual budgets for the boring operation on the factory floor.

“…The response surface methodology was deployed to optimize the parameters. Saleh et al (2021) constructed a novel damper based on magneto-rheological properties to analyse the chatter stability in boring tools. An enhancement in the damping, as well as the damping stiffness for the system was established.…”

In this study, a milling tool with variable mass and stiffness is developed for chatter reduction. The proposed milling tool is hollow with a solid core threaded inside it. As the core is screwed in or out of the tool body, the equal mass and stiffness of the tool are changed. Therefore, the tool's frequency response function (FRF) is changed to affect the stability lobe diagram (SLD) position. Moving the SLDs can stabilize an unstable cutting process. With respect to the FRFs obtained from modal test, the idea is proven using an experimental and analytical approach. The optimum core position for every spindle speed is also presented. The developed tool stability is then investigated in a realistic cutting condition. The cutting process sound analysis and surface finish visual inspection results reveal the performance of the proposed system in chatter reduction of a slender milling tool.

“…Besides, the diverse pressure from stakeholders in the boring operations (i.e. process engineer, manufacturing manager, maintenance manager, the general manager and operators) have also emerged, leading to advance complications in the boring operation decision process (Sathianarayanan et al, 2008;Patel and Deshpande, 2014;Ratnam et al, 2018;Melo et al, 2019;Sastry et al, 2019;Prabhu et al, 2020;Schmidt et al, 2020a,b;Saleh et al, 2021). From the roughness problem description, it is acknowledged that consideration of all aspects of the problem, including the boring operations process parameters, social subsystem, economic subsystem and environmental subsystem are important in the problem formulation (Patel and Deshpande, 2014).…”

This paper establishes how the process engineer in a machine shop could capture the uncertainty and the transition of process parameters to improve the surfaced finish of bored work material (carbon steel IS 2062 GR E250 plates) and select the best parameters to achieve the aim. The fuzzy analytic hierarchy process method incorporating geometric mean and a novel Markov chain oriented weightage scheme were used as inputs into three multicriteria methods of weighted sum model (WSM), weighted product model (WPM) and weighted product model and weighted aggregated sum-product, assessment (WASPAS) model. Published literature data were used to validate the methods and their integrations. The novel Markov chain model borrows ideas from the orthogonal array, random number generation and the transition states of parameters. Finally, the optimal parametric setting idea is used to interprete the final results based on an initial response table determination, which are the averages of the signal-to-noise ratios summarized. The most important results are obtained from the fuzzy AHP-Markov WASPAS method. These are the feed parameter (preference score of 1.624) as the best parameter and the depth of cut with the preference score of 1.188 as the worst parameter. The findings indicate that process engineers should attach the most important interest to the feed rate as it is the most effective controlling parameter of surface finish during the boring operation of carbon steel IS 2062 GR E250 plates. Machining shops can employ the framework to evaluate and predict system performance before financial resource commitment to operations.
