FUNDAMENTAL RELATIONSHIPS BETWEEN GRINDING PARAMETERS.

The author extends the application of the parameters of grinding ability suggested by Lurje and supplies proof of their importance higher than expected. Besides comparison they may also be integrated mathematically for the grinding time and the values thus obtained simultaneously represent also the volume of the metal ground during this time. These values offer the possibility to determine the parameters with iteration using the metal volume ground as measured at two points of time, without the need of measuring radial force. By the method described the parameters are suitable for production planning as well. Namely, by the help of the wheel life constant introduced, the metal volume ground by the grinding wheel during the wheel life may be determined. The calculation accuracy exceeds that required for the practice as proved by the author experimentally.
