Document Type and Number:
WIPO Patent Application WO/2022/168944
Kind Code:
A1
Abstract:
A grinding device (1) comprises: a grinding material drive unit (6) that has a motor for causing a grinding material (5) to rotate; a table drive unit (8) that causes the grinding material (5) to come into contact with a workpiece (20) by causing the grinding material (5) and the workpiece (20) to move relative to each other; an AE sensor (10) that detects acoustic emissions produced when the grinding material (5) and the workpiece (20) come into contact; and a control device (50) that controls the cutting speed of the grinding material (5) with respect to the workpiece (20) by controlling the table drive unit (8). The control device (50) controls the cutting speed by using the output from the AE sensor (10) and the motor current of the grinding material drive unit (6).
