1. A method of using a dressing board in a cutting apparatus, where the cutting apparatus comprises a chuck table that holds a workpiece, a cutting unit that cuts the workpiece held by the chuck table by a cutting blade, a control unit that controls the chuck table and the cutting unit, and an imaging unit connected to the control unit, where the control unit includes a reading part that is connected to the imaging unit and is configured to read a barcode and a two-dimensional code, an information registration part, a specifying part, and a determining part, wherein the method includes:
reading, via the reading part, a barcode and a two-dimensional code that are possessed by a dressing board disposed in the cutting apparatus,
registering, in the information registration part, identification information read from the barcode by the reading part and information relating to properties of the dressing board, read from the two-dimensional code, in association with each other,
registering, using the specifying part, a kind of dressing board suitable for dressing of the cutting blade,
determining, via the determining part, whether or not the properties of the dressing board included in the information relating to the properties read out from the information registration part based on the identification information read by the reading part match the kind of dressing board suitable for dressing of the cutting blade, registered in the specifying part,
dressing the cutting blade with the dressing board such that the two-dimensional code is rendered unreadable by the reading part,
wherein, after the identification information read from the barcode and the information relating to properties of the dressing board have been registered in association with each other, and after the two-dimensional code is rendered unreadable by the reading part:
the reading part sends, to the information registration part: (i) a signal indicating that the two-dimensional code cannot be read, and (ii) the identification information acquired by reading the bar code, and
the information registration part: (i) acquires the information relating to properties of the dressing board that have been registered in association with the identification information sent by the reading part, and (ii) sends the acquired information relating to the properties of the dressing board to the determining part.
