Abstract: A processing apparatus includes a cutting blade mounted on a spindle, the cutting blade having a cutting edge for cutting a workpiece held on a holding table, a measuring portion for measuring an edge projection amount of the cutting edge at a predetermined frequency, and a data processing portion. The data processing portion includes a lower limit recording portion for recording a lower limit of the edge projection amount of the cutting edge as an allowable limit for use of the cutting blade, a storing portion for storing blade information including the edge projection amount measured by the measuring portion and a cutting distance traveled by the cutting blade at the time of measurement of the edge projection amount.
