“…In general, sustainability means fulfilling the present generation's needs without compromising the ability to fulfill the future generations' needs [1]. In more specific terms, sustainability means ensuring material efficiency, energy efficiency, and component efficiency, preferably simultaneously, for all products that inhabit the artificial world [2]. Here, material efficiency is with respect to the usages of materials and takes into account the issues regarding energy consumption and resource depletion while producing the primary materials; it also considers issues like the cost and weight reduction of a product [2][3][4][5].…”

This article elucidates the characteristics of machining forces (an important phenomenon by which machining is studied) using three sets of bimetallic specimens made of aluminum–titanium, aluminum–cast iron, and stainless steel–mild steel. The cutting, feed, and thrust forces were recorded for different cutting conditions (i.e., different cutting speeds, feeds, and cutting directions). Possibility distributions were used to quantify the uncertainty associated with machining forces, which were helpful in identifying the optimal machining direction. In synopsis, it was found that while machining the steel-based bimetallic specimens, keeping a low feed and high cutting speed is the better option, and the machining operation can be performed in both the hard-to-soft and soft-to-hard material directions, but machining in the soft-to-hard material direction is the better option. On the other hand, very soft materials should not be used in fabricating a bimetallic part because it creates machining problems. Cutting power was estimated using the cutting and feed force signals. Manufacturers who support sustainable product development (including design, manufacturing, and assembly) can benefit from the outcomes of this study because parts/products made of dissimilar materials (or multi-material objects) are better than their mono-material counterparts in terms of sustainability (cost, weight, and CO2 footprint).

“…In this respect, one of the plausible solutions is to use bimetallic (or multi-material) components (e.g., Aluminum-cast iron engine block and piston, Aluminum-Copper rod, and alike) because a bimetallic component may perform better than its monometallic counterpart in terms of cost, weight, and environmental impacts of primary material production (Interface Welding, 2014;Ullah et al, 2013b;Ullah et al, 2014). Thus, the usages of such components are likely to increase with the increasing demand of sustainable development.…”

“…Thus, the usages of such components are likely to increase with the increasing demand of sustainable development. Therefore, the surface integrity and other related issues of bimetallic components (e.g., surface metrology) are essential constituents of sustainable manufacturing (Ullah et al 2014).…”

“…Whether or not the above-mentioned standard practice of characterizing a surface is fair enough for a bimetallic component is a matter of investigation because the surface of a bimetallic component might exhibit a different kind of complexity than that of a monometallic component (Nagara et al, 2013;Ullah et al, 2013b, Ullah et al, 2014. This issue is schematically illustrated in Figure 1.…”

A bimetallic component may perform better than its monometallic counterpart in terms of sustainability (i.e., cost, weight, and environmental impacts of primary material production). Thus, the usages of such components are likely to increase in the years to come. Three distinct segments (segments of the constituent materials and joint area) underlie a bimetallic component, necessitating a rather unique surface characterization methodology. The objective of this study is to shed some lights on the surface characterization of a bimetallic component using both conventional and nonconventional approaches. In order to get insights into the surface finish of a bimetallic component, specimens are prepared by joining bars made of commercially pure Titanium (Ti) and Aluminum (Al). The specimens are then turned under some predefined cutting conditions, and the surface profile heights across the joint area are measured by using noncontact surface metrology equipment. The surface profiles are characterized by using the conventional parameters. In addition, the complexity of the surfaces is quantified by using the information content based parameter. Moreover, to quantify the degree of uncertainty, probability/possibility distributions are induced from the profile heights. Both conventional and proposed parameters are equally important for quantifying the surface roughness of a bimetallic component.
