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.

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.
