Use of Neural Networks in Tool Wear Prediction [PDF]

MATEC Web of Conferences, 2019
Modern CNC machine tools include a number of sensors that collect machine status data. These data are used to control the production process and for control of the CNC machine status. No less importantpart of the production process is also a machine tool.

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.

Improved Direct Ink Writing of Liquid Metal Foams via Liquid Additives

Advanced Electronic Materials, EarlyView.
The ability to pattern liquid metal is useful for making soft electrical and thermal devices. Dispensing liquid metal from a nozzle naturally results in the formation of spheroidal droplets, making direct‐write printing challenging. Liquid metal foams containing pockets of air can extrude as filaments, albeit inconsistently.
