Abstract
A grinding method includes a step of imaging a bonded workpiece by a camera in such a manner as to include the outer circumference of a workpiece and the outer circumference of a support component with a larger diameter than that of the workpiece before a step of holding the support component of the bonded workpiece by a holding surface. The grinding method also includes a step of recognizing the outer circumference of the support component and the outer circumference of the workpiece on the basis of the brightness difference between pixels adjacent to each other in a taken image and a step of recognizing the center of the support component from the recognized outer circumference of the support component and recognizing the center of the workpiece from the recognized outer circumference of the workpiece.
