The possibilities for measurement of saw blades wearing

Some effects come into the practice because of decreasing quality of a cutting knife. These effects then influence the whole cutting process. The paper deals with analysis of methods for evaluation of a chain saw wearing. It is necessary to know the methods for measurement of a chain saw wearing because the tool wearing has significant influence on the whole system acting i.e. machine-tool-work piece. The measurement of wearing rate was realized to obtain knowledge about the wearing rate of cutting knives on chain saws. The goal of measurement was to design suitable methods for evaluation of wearing and definition of exactness for used methods. The exactness of used methods is evaluated according to the range of variance. The cutting knife wearing was analyzed by two methods; the results of both methods were compared. In the future it would be very effective to generalize mentioned methodology for measurement of a cutting knife wearing.
