Abstract:
A cutting apparatus includes a cutting unit including a cutting blade that has a cutting edge for cutting a dresser board. An elastic wave detection sensor is disposed in the cutting unit, for detecting an elastic wave produced when the dresser board is cut. The elastic wave detection sensor produces an output signal representing the detected elastic wave when the cutting blade cuts the dresser board and is dressed thereby, the output signal being variable as the cutting blade is progressively dressed by the dresser board. A control unit stores in advance, as a threshold value, the value of the output signal when the dressing of the cutting blade is completed. The control unit stops cutting the dresser board with the cutting blade and finishes the dressing of the cutting blade when the output signal produced by the elastic wave detection sensor reaches the threshold value.

Claim (Index 1):
A cutting apparatus comprising:\n a holding table for holding a plate-shaped workpiece; a cutting unit including a cutting blade that has a cutting edge for cutting the plate-shaped workpiece held on said holding table; a cutting-feed unit for cutting-feeding said holding table and said cutting unit relatively to each other in cutting-feed directions; an indexing-feed unit for indexing-feeding said holding table and said cutting unit relatively to each other in indexing-feed directions perpendicular to said cutting-feed directions; an elastic wave detection sensor disposed in either one of said cutting unit and said holding table, for detecting an elastic wave produced when the plate-shaped workpiece held on said holding table is cut by said cutting blade; and a control unit for controlling said cutting-feed unit and said indexing-feed unit, wherein said elastic wave detection sensor produces an output signal representing the detected elastic wave when said cutting blade cuts a dresser board held on said holding table and is dressed thereby, said output signal being variable as said cutting blade is progressively dressed by said dresser board, and said control unit includes a storage unit that stores in advance, as a threshold value, the value of the output signal produced by said elastic wave detection sensor when the dressing of said cutting blade is completed, and said control unit stops cutting said dresser board with said cutting blade and finishes the dressing of said cutting blade on the dresser board held on said holding table when the output signal produced by said elastic wave detection sensor reaches the threshold value stored in said storage unit.
