The need for capturing knowledge in the digital form design, process planning, production, and inspection has increasingly become an issue manufacturing industries as variety complexity of product lifecycle applications increase. Both data to be well managed quality assurance, lifecycle-impact assessment, design improvement. Some technical barriers exist today that inhibit industry from fully utilizing processing, knowledge. primary barrier is a lack well-accepted mechanism enables users...
In this paper, we advocate for a more harmonized approach to model development additive manufacturing (AM) processes, through classification and metamodeling that will support AM process composability, reusability, integration. We review several types of models use the direct metal powder bed fusion provide illustrative examples proposed metamodel approach. describe how coordinated can be used extend modeling capabilities by promoting composability. As part future work, framework is...
The need for an open, inclusive, and neutral procedure in selecting key performance indicators (KPIs) sustainable manufacturing has been increasing. reason is that manufacturers seek to determine what measure improve environmental sustainability of their products processes. A difficulty arises understanding specific from many stand-alone indicator sets available. This paper presents a individual select KPIs measuring, monitoring, improving aspects the basis guideline, being proposed...
Abstract Multi-scale, multi-physics, computational models are a promising tool to provide detailed insights understand the process–structure–property–performance relationships in additive manufacturing (AM) processes. To take advantage of strengths both physics-based and data-driven models, we propose novel, hybrid modeling framework for laser powder bed fusion (L-PBF) process. Our unbiased model-integration method combines physics-based, simulation data, measurement data approaching more...
Intrahepatic cholangiocarcinoma (ICC) is a common primary hepatic tumors with 5-year survival rate of less than 20%. Therefore, it crucial to elucidate the molecular mechanisms ICC. Recently, advance high-throughput chromosome conformation capture (Hi-C) technology help us look insight into three-dimensional (3D) genome structure variation during tumorigenesis. However, its function in ICC pathogenesis remained unclear. Hi-C and RNA-sequencing were applied analyze 3D structures gene...
The important issue of mechanical assemblies has been a subject intense research over the past several years. Most electromechanical products are components, for various technical as well economic reasons. This paper provides an object-oriented definition assembly model called Open Assembly Model (OAM) and defines extension to NIST Core Product (NIST-CPM). represents function, form, behavior both system level conceptual associated hierarchical relationships. way tolerance representation...
Additive manufacturing (AM) has been envisioned by many as a driving factor of the next industrial revolution. Potential benefits AM adoption include production low-volume, customized, complicated parts/products, supply chain efficiencies, shortened time-to-market, and environmental sustainability. Work remains, however, for to reach status full production-ready technology. Whereas ability create unique 3D geometries generally proven, challenges remain, including lack (1) data manageability...
This paper is devoted to developing an integrated model minimise energy consumption while maintaining desired productivity in Bernoulli serial lines with unreliable machines and finite buffers. For small systems, such as three- four-machine buffers, exact analysis optimally allocate production capacity introduced. medium size systems (e.g. larger or five-machine buffers), aggregation procedure evaluate line rate Using it, optimal allocation of machine efficiency searched consumption....
Abstract To advance additive manufacturing (AM), a scalable architecture is needed to structure, curate and access the data from AM R&D projects that are conducted evaluate new materials, processes technologies. Effective project metadata management enables sharing of domain knowledge. This work introduces an modeling capture pedigree information which traceability material. overall model includes five modules covering about (1) management, (2) feedstock (3) building post processing, (4)...
Computer-aided process planning (CAPP) performs an important function, integrating product design with production, but has not kept pace CAD/CAM developments. More and more attention been paid to CAPP automation, intelligence CAD/CAPP/CAM integration, a plethora of prototype systems developed. However, applications are less than satisfactory. With the objective improving usability adaptability, this paper proposes object-oriented manufacturing resources modelling (OOMRM) agent-based (AAPP)....
Recently, The number and types of measurement devices that collect data is used to monitor Laser-Based Powder Bed Fusion Metals processes inspect Additive Manufacturing (AM) metal parts have increased rapidly. Each device generates in a unique coordinate system format. Data alignment the process spatially aligning different datasets single system. It part broader called "Data Registration". This paper provides data-registration procedure includes an example single, reference, Such reference...
