DIRECT SPLINE INTERPOLATION ON CNC-MACHINE TOOL

IFAC Proceedings Volumes, 1985
Abstract This paper introduces a method of direct cubic spline interpolation on CNC-machines based on a single board microcomputer, and the corresponding format of NC instructions. It can be used to control directly the machine tool to generate the required movements defined by the spline, according to given parameters.

Nanocellulose Alleviates Intrahepatic Cholestasis of Pregnancy via Gut Microbiota‐Mediated Bile Acid Homeostasis

Advanced Science, EarlyView.
Nanocellulose, derived from microcrystalline cellulose (MCC) through sulfuric acid hydrolysis or mechanical grinding to produce CNC or CNF, was tested in a rat ICP model. Particularly, CNF improved gut microbiota composition, reduced secondary bile acid metabolism, and restored bile acid homeostasis through modulation of the gut–liver axis.

Application of Machine Tool Thermal Error Compensation in Digital Twin-based System

Journal of Harbin University of Science and Technology
Thermal error significantly affects machining accuracy, demanding careful control. A robust system integrating a highly accurate thermal error model is the key to this control. This can be achieved through deep learning-based models.

Electrohydraulic Folding Ring Actuators for Radially Contracting Applications

Advanced Science, EarlyView.
This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...
