Measurement of Diamond Abrasive Grain Temperature in Grinding using Infrared Radiation Pyrometer

摘要

The temperature of the diamond abrasive grain in single-point grinding was measured using a two-color pyrometer with an optical fiber. A conical, single-point diamond cutting tool was used as the cutting grain, and titanium and tungsten carbide were used as workpieces. Results show that the infrared rays radiated from the tool-workpiece interface and transmitted through the diamond tool were accepted by the optical fiber and led to infrared detectors with different spectral sensitivity. The tool tip temperature ranged from 400°C - 550°C on the titanium and 850°C - 1400°C on the tungsten carbide for cutting speeds ranging from 12.1m/s-24.3m/s.
