Cutting apparatus, holder position coordinate correcting method, and non-transitory computer-readable non-volatile storage medium

A holder position coordinate correcting method for a cutting apparatus including:

• a container including a holder in which a workpiece having an adapter attached thereto is held;
• a cutter to cut the workpiece;
• a conveyor to grip the adapter to convey the workpiece from the container to the cutter;
• a reading target applied to the adapter;
• an optical sensor to optically read the reading target;
• and
• a controller to control the cutter, the conveyor, and the optical sensor, the controller including a memory to store a position coordinate of the holder and a theoretical position coordinate of the reading target associated with the position coordinate of the holder, wherein
• the correcting method comprises:
• reading, with the adapter held in the holder, the reading target using the optical sensor to acquire an image of the reading target;
• determining, in accordance with the image acquired in the reading step, an actual position coordinate of the reading target to calculate a correction value from a difference between the actual position coordinate and the theoretical position coordinate;
• and
• updating, using the correction value calculated in the determining step, the position coordinate of the holder stored in the memory.

A non-transitory computer-readable non-volatile storage medium for a cutting apparatus including:

• a container including a holder in which a workpiece having an adapter attached thereto is held;
• a cutter to cut the workpiece;
• a conveyor to grip the adapter to convey the workpiece from the container to the cutter;
• a reading target applied to the adapter;
• an optical sensor to optically read the reading target;
• and
• a controller to control the cutter, the conveyor, and the optical sensor, the controller including a memory to store a position coordinate of the holder and a theoretical position coordinate of the reading target associated with the position coordinate of the holder;
• wherein
• the storage medium stores a computer program for causing a computer to function as:
• a reader to read, with the adapter held in the holder, the reading target using the optical sensor to acquire an image of the reading target;
• a calculator to determine, in accordance with the image acquired by the reader, an actual position coordinate of the reading target to calculate a correction value from a difference between the actual position coordinate and the theoretical position coordinate;
• and
• an updater to update, using the correction value calculated by the calculator, the position coordinate of the holder stored in the memory.
