摘要： This is a method for dimple processing for forming dimples (22) on a workpiece (20) utilizing a rotary cutting tool (1). The rotary cutting tool (1) is prepared that has a cutting edge (3) axially extending from a position at the leading end of the rod-shaped main body (2) and offset from an axis (5). The rotary cutting tool (1) is set such that the axis (5) of the rotary cutting tool (1) is inclined to a vertical line of the processing surface (21) of the workpiece (20). The rotary cutting tool (1) and the workpiece (20) are relatively delivered such that the rotary cutting tool (1) is moved along the processing surface (21) while the rotary cutting tool (1) is rotated about the axis (5). The processing surface (21) is cut by the cutting edge (3) to form the dimples (22), which are spaced apart from each other, on the processing surface (21).

摘要： An end mill (1) having a plurality of cutting edges (5) on a surface of a rod-shaped main body (4) is rotated about an axis (6) and relatively moved in a feed direction orthogonal to the axis (6) along a workpiece (20). The end mill (1) is also moved relative to the workpiece (20) in the axial direction while it is being relatively moved in the feed direction. In this way, a plurality of dimples (22) are formed to be relatively spaced apart from each other on the workpiece (20). The plurality of dimples (22) arranged side by side in the feed direction are formed so as to be offset in the axial direction while partially overlapping with respect to each other in the axial direction.

摘要： A tipped saw blade (10) has a base metal (12) and a plurality of tips (14) attached on an outer periphery of the base metal (12). The plurality of tips (14) include long tips (30) having a setting line length in a radial direction of 4 mm or more, and short tips (40) having a setting line length in the radial direction of less than 4 mm. A number of the long tips (30) is 2 to 15% of sum total of numbers of the long tips (30) and short tips (40), and is two or more.

摘要： A plurality of dimples (3) are formed on a processing surface (2) of a workpiece. An aspect ratio of the dimples (3) is 5.0 or more and 50.0 or less, the aspect ratio being a ratio of a vertical length (3b) of the dimple in a longitudinal direction to a lateral length (3c) of the dimple in a lateral direction orthogonal to the longitudinal direction.
