Heat Pulses

The heat pulses produced by cutting grains in a workpiece were measured using an infrared radiation pyrometer connected by means of an optical fiber. The results obtained were compared with those from a thermocouple to investigate the effect of differences in response speed on the output. The I.R.P., using an InAs cell as a detector which has a response time in the order of μs, can detect heat pulses with great accuracy and its signal trace versus time has many sharp peaks. The thermocouple formed by spot welding is inferior in response speed, and less accurate in registering heat pulses.

Grinding Power

The grinding temperature in the surface layer of a ceramic workpiece was measured using an IRP (infrared radiation pyrometer) connected by means of an optical fiber. Two types of optical fiber were employed: fluoride fiber and chalcogenide fiber. Si3N4, SiC, and Al2O3 were used as the work materials. The output waves of I.R.P. of Si3N4 and Al2O3 appear as curves with many peaks which are related to the infrared energy emitted from the cutting grains, but that of SiC shows no peaks at all. The highest grinding temperature was obtained in the case of Si3N4 whose grinding power is the largest of these three materials. The temperature distribution in the surface layer of the ceramics was much different from that of the steel.

History Of

The temperature of cutting grains on wheel surface was measured by means of a new method, in which an optical fiber accepts the infrared flux radiated from the cutting grains and transmits it to an infrared detector InAs cell. This pyrometer makes it possible to observe the history of each cutting grain on the wheel surface. It was found that the temperature of cutting grains at 4.2 ms after cutting is distributed in the range of 500°C to 1400°C, and their mean temperature is 820°C.
