Life prediction of NC machine tools based on DT technology and LSTM technology

Frontiers in Mechanical Engineering
In order to solve the problems of physical model simplification error, insufficient fusion of multi-source monitoring data, and low accuracy of life prediction in traditional CNC machine tool life prediction methods, this study proposes a CNC machine ...

Fatigue Strength in Additive Toolmaking: A Study of Metal Binder Jetting and Electron Beam Melting for Processing Carbide‐Rich Cold‐Work Tool Steels

steel research international, EarlyView.
Focusing on the critical tap hole region of the blast furnace, this work examines binder characteristics, prepares tap hole clay with different formulations, and evaluates their physical properties. The findings confirm the advantages of composite binders and offer a new binder option for tap hole clay.

Toward the Application of Multiaxial Failure Criteria: Mean Stress Sensitivity of Carbide‐Rich, High‐Alloy PM‐HIP Tool Steels Under Axial and Torsional Cyclic Loading

steel research international, EarlyView.
This study quantifies axial and torsional long‐life fatigue (LLF) behavior of three carbide‐rich PM‐HIP tool steels, correlating LLF strength with intrinsic defect size and cleanliness, thereby extracting material‐specific mean stress sensitivities and Haigh diagrams.

Tangent Blow‐Ups for Processing Non‐Manifold Geometry

Computer Graphics Forum, EarlyView.
Abstract Many geometry processing pipelines implicitly assume their input data is a manifold, or is sampled from one, with a unique tangent plane at every point. Geometric data, however, routinely contains sharp features like edges, corners, self‐intersections, branching junctions, and other singularities, rendering standard methods ill‐defined at ...

The Mokuhanga Technique Today: An Exploration of Traditional Japanese Art in the Artistic and Educational Context

International Journal of Art &Design Education, EarlyView.
Abstract In recent years, there has been a growing interest in the Mokuhanga technique, a traditional Japanese printmaking method, and its contemporary evolution. This article explores the history of this discipline, its technical uniqueness, and its resurgence in the current context, with particular attention to its development in Spain.

UC2‐ESP: A general‐purpose framework for open‐source microscopy control

Journal of Microscopy, EarlyView.
Abstract Building the optical setup for investigating biological questions comes with challenges. A major such challenge is setting up and synchronizing the control of multiple hardware components such as stages, cameras and lasers. With UC2‐ESP, we present a low‐cost electronics system powered by the ESP32 microcontroller (∼$10), designed as an ...

‘Civilizing’ Smallholders Through Oil Palm: The Politics of Subsumption Across Southern Mexico's Commodity Frontiers

Journal of Agrarian Change, EarlyView.
ABSTRACT While most frontier studies associate commodity expansions with dispossession, I argue that such expansions can also function as ‘civilizational’ projects aimed at overcoming traditional farming and creating new rural subjects better suited to the needs of capitalist development. Using a Gramscian approach to study subsumption, I analyse three

The Impact of Digital Technologies on Skills‐to‐Job Mismatches

New Technology, Work and Employment, EarlyView.
ABSTRACT A pervasive discourse calls for worker upskilling amid ongoing digital transformation. This study introduces a skills‐to‐job mismatch perspective into research on the digital transformation of work by conceptualising technological adoption as a process that reshapes the relationship between workers’ skill endowments and evolving job ...
