Grinding process supervision via information distance measure.

In this paper, the effectiveness of some approaches to on-line supervision of the grinding process is discussed. The advantages and corresponding shortcomings of some indirect methods previously recommended are compared. The authors recommend the information distance measure as a new criterion for distinguishing the different stages of the grinding process. Experiments have verified the advantages of this criterion in the terms of its efficiency, reliability, adaptability, computer storage saving and simplicity of instrumentation. [ABSTRACT FROM AUTHOR]
