Abstract:
Disclosed herein is a cutting apparatus having a cutting blade for cutting a workpiece held on a chuck table. The cutting apparatus includes an elastic wave detecting sensor for detecting an elastic wave due to the rotation of the cutting blade, a reference data storing section configured to store reference data as a set of reference processing elastic wave data detected in previously processing the workpiece and reference idling elastic wave data detected in the condition where the cutting blade is idling before processing, a threshold value storing section configured to store a threshold value set on the basis of the reference processing elastic wave data, a ratio calculating section configured to calculate the ratio of idling elastic wave data detected at the time just before actually processing the workpiece to the reference idling elastic wave data, and a determining section configured to divide processing elastic wave data detected during the actual processing by the ratio calculated by the ratio calculating section to thereby obtain a corrected value and then determine that the actual processing is abnormal when the corrected value is greater than the threshold value.

Claim (Index 1):
A cutting apparatus comprising:\n a chuck table configured to hold a workpiece; cutting means having a cutting blade for cutting said workpiece held on said chuck table; cutting water supplying means for supplying a cutting water to said cutting blade; an elastic wave detecting sensor provided in said cutting means for detecting an elastic wave due to the rotation of said cutting blade; and control means for controlling said chuck table, said cutting means, said cutting water supplying means, and said elastic wave detecting sensor; said control means including\n a reference data storing section configured to store reference data as a set of reference processing elastic wave data detected in previously processing said workpiece under predetermined processing conditions and reference idling elastic wave data detected in the condition where said cutting blade is idling without cutting said workpiece as supplying said cutting water before processing, \n a threshold value storing section configured to store a threshold value set on the basis of said reference processing elastic wave data, \n an idling elastic wave data storing section configured to store idling elastic wave data detected in the condition where said cutting blade is idling without cutting said workpiece as supplying said cutting water, with arbitrary timing and also store the time of detection with said arbitrary timing, \n a ratio calculating section configured to calculate the ratio of said idling elastic wave data at the time just before processing to said reference idling elastic wave data, and \n a determining section configured to divide processing elastic wave data detected during processing by said ratio calculated by said ratio calculating section to thereby obtain a corrected value and then determine that the processing is abnormal when said corrected value is greater than said threshold value.
