Abstract
Official abstract text for this publication.
A dressing board for dressing a tip end of a cutting blade includes a lower surface to be held on a table and a slanted surface inclined to the lower surface and oriented across a direction in which the cutting blade is movable relatively to the table such that the tip end of the cutting blade moves across and over the slanted surface when the cutting blade is moved relatively to the table.
First claim
Opening claim text (preview).
What is claimed is: 1 . A dressing board for dressing a tip end of a cutting blade, comprising: a lower surface to be held on a table; and a slanted surface inclined to the lower surface and oriented across a direction in which the cutting blade is movable relatively to the table such that the tip end of the cutting blade moves across and over the slanted surface when the cutting blade is moved relatively to the table. 2 . The dressing board according to claim 1 , wherein an angle formed between the lower surface and the slanted surface is in a range from 30° to 60°. 3 . A shape determining method of determining a shape of a tip end of a cutting blade, the method comprising: holding a lower surface of a dressing board on a table, the dressing board having a slanted surface inclined to the lower surface thereof; causing the tip end of the cutting blade to cut into the dressing board while the cutting blade is being moved relatively to the table such that the tip end of the cutting blade moves across and over the slanted surface that is oriented across a direction in which the cutting blade is movable relatively to the table; and confirming the shape of a processing mark left on the slanted surface by the tip end of the cutting blade that has moved across and over the slanted surface, from a side of the dressing board opposite the lower surface thereof, thereby determining the shape of the tip end of the dressing board. 4 . The shape determining method according to claim 3 , wherein the tip end of the cutting blade cuts into the dressing board and moves across and over the slanted surface without moving across an end of the slanted surface at the lower surface of the dressing board. 5 . The shape determining method according to claim 3 , comprising: determining the shape of the tip end of the cutting blade as curved if an end of the processing mark confirmed from the side of the dressing board opposite the lower surface thereof is of a curved shape. 6 . The shape determining method according to claim 4 , comprising: determining the shape of the tip end of the cutting blade as curved if an end of the processing mark confirmed from the side of the dressing board opposite the lower surface thereof is of a curved shape.
