Scanning optical pyrometer for measuring temperatures in hollow cathodes [PDF]

, 2007
Life-limiting processes in hollow cathodes are determined largely by the temperature of the electron emitter. To support cathode life assessment, a noncontact temperature measurement technique which employs a stepper motor-driven fiber optic probe was ...

Influence of cutting fluid on tool edge temperature in end milling titanium alloy

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2015
This study investigates the influence of cutting fluid on the cutting temperature in end milling of a titanium alloy. As the cutting temperature, the tool edge temperature was measured using a two-color pyrometer with an optical fiber.

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.

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.
