Abstract This article investigates the vibration cutting process of Ti6Al4V alloy numerically and theoretically. The Coupling Eulerian-Lagrangian finite element models with one-tool and double-tool are established, to simulate the cutting processes with tool forced vibration and self-exited vibration respectively. It is shown that low-frequency forced vibration aggravates the periodic shear banding instability and increases the cutting force amplitude, whereas high-frequency forced vibration can...

Abstract Process mining offers the potential for internal logistics process improvement using data. While there exists a massive amount of data, identifying and understanding relevant data across different information systems and complex data models is difficult. To address this issue, ontologies can be used to formalize a shared understanding. This paper aims to provide an extended internal logistics ontology focusing the process perspective. Existing internal ontologies are reviewed, compared ...

Abstract On the basis of theory of the Capability Maturity Model and the "China Manufacturing 2025" plan, this paper studies the maturity model of intelligent manufacturing based on the current situation in China from three aspects: maturity level, capability factor and maturity requirements. According to the analysis results by self-evaluation platform of China Electronics Standardization Institute, the maturity of intelligent manufacturing capabilities of most manufacturing companies in China ...

Abstract Fashion industry has a huge environmental impact, with increasing consequences all around the world. It is clear that the fashion consumers and stakeholders need to evaluate present status quo, according principles of sustainability and circular economy. Circular economy can be a guideline for the fashion industry, promoting product development focused on sustainable products (e.g., green products and cleaner technologies) and recyclability (e.g., upcycling and reuse of fibers from disp...

Abstract The variability of the arrival and service processes has a strong impact on the performance of supply chain networks (SCNs), especially when the reverse flow to the manufacturer is considered. This paper proposes to use approximate analytical models to quickly evaluate the performance of SCN configurations during the design phase of the forward and reverse supply chains. The models are applied to the case of scrap-based steel production in which the role of the reverse flow is higher co...
Abstract The change of the dominant design in the automotive industry from internal combustion engines to alternative power trains requires an adaptation of the product portfolio and a transformation of the production system. In the transition phase, an increased changeability is needed. This paper proposes a procedure for managing this transition, based on an integrated assessment of product, production planning and already existing production facilities. A modular product kit reduces the impac...
