Problems solved by technology

However, when even a part of the area where the two-dimensional code is arranged is cut by a cutting tool, the two-dimensional code cannot be read
Therefore, when the use of the trimming board is temporarily suspended and removed from the cutting device, and thereafter when the trimming board is intended to be used again, information related to the trimming board may not be confirmed from the two-dimensional code.

Embodiment Construction

[0034] An embodiment of one embodiment of the present invention will be described with reference to the drawings. This embodiment of the invention is a trimming plate, a method of using the trimming plate, and a cutting device. figure 1 It is a perspective view which schematically shows the trimming board of this embodiment. Such as figure 1 As shown, a barcode 3 and a two-dimensional code 5 are arranged on the front side of the trimming plate 1 .

[0035] This dressing plate 1 is used for dressing of a cutting tool mounted on a cutting machine. The cutting tool has a cutting abrasive including abrasive grains and a bonding material (bonding material) holding the abrasive grains. Since the workpiece can be brought into contact with the abrasive grains in a state where the abrasive grains are properly exposed from the bonding material, the workpiece can be appropriately cut. However, in an unused cutting tool or a cutting tool whose cutting ability has been reduced due to c...

Abstract

The invention provides a dressing board, a use method of the dressing board, and a cutting apparatus. Even if the dressing board is cut by a cutting tool, the information related to the dressing platecan be obtained. A dressing plate is used for dressing cutting tools. The dressing board having, on a surface, a two-dimensional code including information relating to properties of the dressing board and a barcode including identification information associated with the information relating to the properties is provided. Furthermore, there is provided a cutting apparatus including a determiningpart that determines whether or not the properties of the dressing board read out from an information registration part based on the identification information match the kind of dressing board suitable for dressing of a cutting blade.

Description

technical field [0001] The present invention relates to a dressing plate used when dressing a cutting tool, a method of using the same, and a cutting device with a cutting unit. Background technique [0002] In the manufacturing process of a device chip, grid-like dividing lines called streets are set on the front surface of the wafer, and devices are formed in regions defined by the dividing lines. Individual device chips are formed when these wafers are cut along planned dividing lines. [0003] Among the wafers are semiconductor device wafers made of silicon, gallium arsenide, etc., optical device wafers made of sapphire, SiC (silicon carbide), etc., packaging substrates made of resin or metal, ceramic substrates, glass substrates, and the like. [0004] Cutting is performed, for example, by a cutting device having a cutting unit including an annular cutting tool. The cutting unit has a cylindrical main shaft as a rotation axis, and a cutting tool is attached to the fro...
