In this paper, we advocate for a more harmonized approach to model development for additive manufacturing (AM) processes, through classification and metamodeling that will support AM process model composability, reusability, and integration. We review several types of AM process models and use the direct metal powder bed fusion AM process to provide illustrative examples of the proposed classification and metamodel approach. We describe how a coordinated approach can be used to extend modeling capabilities by promoting model composability. As part of future work, a framework is envisioned to realize a more coherent strategy for model development and deployment.

Purpose How can customer service be so bad in an era when companies collect endless data on customer interactions? The purpose of this paper is to contribute to the important challenge of elevating customer service delivery by providing guidelines for when and how to select optimal measures of customer service measurement using a new decision framework. Design/methodology/approach The paper uses a comprehensive, multi-dimensional review of extant literature related to customer service, journey mapping and performance measurement and applied a qualitative, taxonomic approach for model development. Findings A process model and customer journey mapping framework can facilitate the selection and application of appropriate and relevant customer service experience metrics to enhance customer service experience strategies, creation and delivery. Research limitations/implications The taxonomy of customer service metrics is limited to current publicly and commercially available metrics. The dynamic nature of the customer service environment necessitates continuous updates of the model and framework. Practical implications Selection of customer service performance measures should match relevant stages of the customer journey; use perception-based, operational and outcome-based metrics that track employee and customer behaviours; improve omni-channel measurement; and integrate data-sharing and benchmark measurement initiatives through collaboration with customer service communities. Originality/value A reimagined perspective is offered to the complex challenge of measuring and improving customer service, providing a new decision-making framework for customer service experience measurement and guidance for future research.

Purpose Calls for dialectical learning process model development in learning organizations have largely gone unheeded, thereby limiting conceptual understanding and application in the field. This paper aims to unify learning organization theory with a new understanding of Hegelian dialectics to trace the development of the storytelling learning organization. The “storytelling learning organization” is a conceptual framework presented along with criteria to evaluate different kinds of dialectical development claims in “storytelling learning organization” work that are bona fide instances of one or another dialectical ontology ranging from Marxian, to Hegelian, to Brierian, to Žižekian. Design/methodology/approach Ontological evaluation and critique of a variety of “storytelling learning organization” practices posit different dialectical ontology and consequences for theory and practice. Through a case example of business process reengineering (BPR) in a “public research university (PRU)”, the storytelling of “schooling” versus “education” ideas and practices, in a place, in a period and in material ways of mattering, never achieves synthesis. The dialectical development of resistance to implementation evolves toward transcendence into irreducible oppositions of ontological incompleteness – the essence of a learning organization. Findings This ontological analysis focuses on the use of ideas and practices by opposing storytelling agents and actants to uncover a learning organization’s dialectical development in its own storytelling, its narrative and counter-narrative enactments, and its attempts to unpack contradictions. The PRU under study has gone through a series of financial crises, and its learning organization responses were downsizing staff and faculty positions and implementing BPR in ways that worsened the situation. The process resulted in staff and faculty leaving even before the reorganization was completed and enrollment dropped dramatically, in great part due to the negative press and the excessive standardization of the curriculum that accompanies “schooling” displacing acts of “education” practices and ideations. Meanwhile, the administrators are still trying to manage the narrative and control it so as to forestall additional attrition. Originality/value The theory of “storytelling learning organization” is original. The question answered here has practical value because institutions have choices to make concerning the kind of dialectical narrative and counter-narrative development that is cultivated, and there are options for transforming or moving to an alternative narrative and counter-narrative development process. The analysis of the case also illustrates a pattern of intervention that is, on the one hand, unsuccessful in developing “higher” education and, on the other hand, successful in shutting down the efficacy of a PRU by centrist use of reengineering to accomplish more schooling, more downsizing and more installation of “academic capitalism” ideas and practices.

A cutting-process model addressing the chip removal and edge ploughing mechanisms separately yet simultaneously is presented. The model is developed such that it is readily applicable in an industrial setting, its coefficients have physical meaning, and it can be calibrated with a concise quantity of orthogonal cutting data. The total cutting and thrust forces are each the summation of its individual components acting on the rake face and clearance face. These components are calculated using the rake and effective clearance angles from the normal and friction forces acting on each of these tool surfaces. These normal and friction forces are calculated by the chip removal and edge ploughing portions of the model, respectively, using four empirical coefficients. To calculate the clearance face forces, the interference volume is required, the calculation of which is based on a geometrical representation of the clearance face interference region. This representation is characterized in part by the depth of tool penetration, which is influenced by thermal energy generation and is therefore determined using a fifth empirical model.
