Electronic based accuracy enhancement of CNC machine tools [PDF]

open access: yes
The need for better machine tool accuracy is discussed together with the factors which can affect machine tool accuracy. A study is made of the various techniques adopted for the reduction of errors in machine tools. The concept of error compensation

Design of a Novel Gripping Mechanism and Dual Manipulator Robotic System for Apple Harvesting Using Tractor

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The architecture of apple orchards can be converted to easier operation by implementing the use of a low‐cost, tractor‐mounted, dual manipulator based on a robotic harvesting system with lower degrees of freedom (DoF). To accurately avoid injuries by detecting apples, an efferent, real‐time vision system that includes a new gripping mechanism ...

An Enhanced Soft‐Containing Gripper for Pick‐And‐Place of Oyster Products at Extreme Handling Speed

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Soft robotic grippers have been developed for high‐speed handling of soft, fragile foods. For example, our previously designed soft‐containing gripper has been implemented on food production lines. However, existing soft robotic grippers remain inadequate for food pick‐and‐place tasks at extreme handling speeds (e.g., > 70 pcs/min).

European Circular Economy Structural Typology Based on Multivariate Analysis of Latent Dimensions and Transition Pathways

open access: yesSustainable Development, EarlyView.
ABSTRACT Transition towards a circular economy has become a strategic priority for the European Union, although Member States continue to exhibit substantial differences in economic performance, resource efficiency and circular economy implementation. Understanding these structural differences is essential for designing effective policy interventions ...

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

open access: yesFrontiers 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 ...

An Ergonomic Customizable Soft Robotic Glove Toward Personalized Hand Rehabilitation

open access: yesSmartBot, EarlyView.
Soft robotic gloves for hand rehabilitation are often limited by poor fit and uneven pressure on the fingers. Here, the authors report an ergonomic all‐fabric glove whose dual‐action actuators are tailored to individual finger geometry by CNC heat sealing, with symmetrical chambers that distribute interface pressure more evenly. Weighing only 90 g, the

Bidirectional Plant‐Microneedle Responses to Guide Biomaterial Design

open access: yesSmall, EarlyView.
We examine bidirectional interactions between plants and polymeric microneedles to develop effective compound delivery strategies. Material chemistry and architecture determine stability in the plant environment, cargo–matrix interactions, and the magnitude and duration of the plant response. Plant microneedles should therefore be designed as a coupled

Making Meets Informal Innovation: Formalisation, Access and Openness in Indian Makerspaces

open access: yesCreativity and Innovation Management, EarlyView.
ABSTRACT Makerspaces and fabrication labs (fablabs) are inclusive and open infrastructures. They democratise access to tools and technologies and facilitate bottom‐up innovation. Research on these spaces thus highlights the importance of openness, community orientation and the ability to foster informal experimentation that these spaces enable. In this

Tangent Blow‐Ups for Processing Non‐Manifold Geometry

open access: yesComputer 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 ...
