Temperature Measurement of Wire Electrode in Wire EDM by Two-color Pyrometer

Procedia CIRP, 2018
Abstract In wire electrical discharge machining (EDM), it is considered that one of the major reasons why the wire electrode breakage occurs is the increase of temperature of wire electrode during machining. This is because the increase of the temperature leads to the decrease in the mechanical strength of wire electrode.

Measurement of Tool-Chip Interfaee Temperature in Turning Using Two-Color Pyrometer

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1999
The temperature of interface between a cutting tool and a chip in dry and wet turning is measured using two color pyrometer with a fused fiber coupler. A translucent Alumina sintered under HIP (Hot Isostatic Pressing) is used as the cutting tool, and 0.45% carbon steel (S45C) is used as a workpiece.

Investigation of laser consolidation process for metal powder by two-color pyrometer and high-speed video camera

CIRP Annals, 2013
Abstract This paper deals with the measurement of surface temperature on metal powder during the laser consolidation process with two-color pyrometer. Additionally, the aspect of selective laser sintering (SLS) and selective laser melting (SLM) of metal powder is visualized with high speed video camera. As a result, the surface temperature during the

Measurement of Flush Temperature of Ceramics Irradiated with CO2 Laser. Application of Two-color Pyrometer Using Fused Fiber Coupler.

Journal of the Japan Society for Precision Engineering, 1995
A new type of Infrared Radiation Pyrometer using a fused fiber coupler is made, and its characteristics are investigated theoretically and experimentally. This pyrometer can be applied to measure the flush temperature of a small area on ceramics (PSZ) when it is irradiated with CO2 laser.

Temperature-Tunable Heliconical and Ferroelectric Nematics for White Lasing. [PDF]

Adv Mater
The discovery of the ferroelectric nematic (NF) phase in 2017 and the spontaneous symmetry‐breaking of the ferroelectric twist‐bend nematic (NTBF)phase in 2024 have made major breakthroughs in the context of self‐assembly materials. This study presents pioneering temperature and voltage‐tunable lasing in both phases, demonstrating multicolor and in ...
