CUTTING INSERT, CUTTING EDGE-REPLACEABLE ROTARY CUTTING TOOL AND ROTARY CUTTING METHOD

A cutting insert (1) has a plate shape centered on an insert center axis (C). The cutting insert (1) includes a front surface (11) and a back surface (12) facing an insert axial direction, an outer peripheral surface (13) facing outward in an insert radial direction, and a cutting edge (14) at an in...

Zusammenfassung:A cutting insert (1) has a plate shape centered on an insert center axis (C). The cutting insert (1) includes a front surface (11) and a back surface (12) facing an insert axial direction, an outer peripheral surface (13) facing outward in an insert radial direction, and a cutting edge (14) at an intersecting ridge line between the front surface (11) and the outer peripheral surface (13). The back surface (12) has a flat shape perpendicular to the insert center axis (C). The outer peripheral surface (13) includes a flank surface (20) coupled. The flank surface (20) is inclined inward in the insert radial direction as extending in the insert axial direction from the front surface side to the back surface side. The front surface (11) includes a rake surface (15). The rake surface (15) is inclined from a back surface side to a front surface side in the insert axial direction as extending inward in the insert radial direction from the cutting edge (14).
