“…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.…”

“…Lotfi et al (2020) analyzed a threedimensional vibration approach to assess its impact on surface integrity during the boring process. Lawrance et al (2020a) built up an impact damper attached to the boring tool to lessen the tool vibration and enhance the tribological characteristics of the work material. The attempt yielded positive results of tool vibration suppression and the improvement of the work material's tribological characteristics.…”

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.
