Abstract
In surface grinding of steel, the temperature in the surface layer of the workpiece and the temperature of cutting grains on wheel surface are measured by means of a new method, in which an optical fiber accepts the infrared flux radiated from the object and transmits it to an infrared detector InAs cell. This I.R.P. is suitable for measuring the temperature of a very small object whose temperature changes rapidly. The influence of the physical properties of workpiece and grinding conditions on the grinding temperature and the thermal partition coefficient are investigated. A carbon steel, a stainless steel and a cast iron are used as work materials. The thermal partition coefficients obtained by experimental results are compared with those obtained theoretically.
