Document Type and Number:

WIPO Patent Application WO/2012/172710

Kind Code:

A1

Abstract:

[Problem] To improve removal of chips generated when performing high feed processing of thin-walled materials such as impellers using a multi-edge endmill. [Solution] In a multi-edge endmill (1) having a cutting edge part (3) provided with multiple cutting edges and flutes (8) formed between cutting edges that are adjacent in the direction of rotation around the tool axis (O), the rake face of the cutting edge is configured from: the rake face (6a) of an end cutting edge (6) from the tool axis (O) to the outer circumference of the shank (2); the adjacent rake face (5a) of a corner R edge (5) that forms a surface different from the rake face (6a) of the end cutting edge (6); and the adjacent rake face (4a) of a peripheral cutting edge (4) that forms a surface different from the rake face (5a) of the corner R edge (5). Between the rake face (6a) of an end cutting edge (6) and the flank (6b) of the end cutting edge (6) that is adjacent on the forward side thereof in the direction of rotation (R), a gash (7), which configures a space that is continuous with the flute (8), is formed, and one surface that configures the gash (7) also serves as the rake face (6a) of the end cutting edge (6).
