Method for manufacturing component, processing apparatus, and component

A processing device comprising:

• an end mill that includes a bottom edge formed in a curved convex shape and a radial edge provided at a corner and formed in a shape of an arc;
• a drive unit that drives the end mill;
• and
• a control unit that controls the drive unit,
• wherein the control unit includes a planar portion formation unit controlling the drive unit so as to form only a planar portion, which is adjacent to a fillet-shaped portion, on a workpiece so that an unprocessed portion remains on the fillet-shaped portion of a shape as a processing target, and a fillet formation unit controlling the drive unit so as to form the fillet-shaped portion on the workpiece by the radial edge in a single pass.

A component comprising:

• a planar portion;
• and
• a fillet-shaped portion that is adjacent to the planar portion and has curvature different from curvature of the planar portion,
• wherein a convex portion is formed in a height direction on the planar portion side of a boundary portion between the fillet-shaped portion and the planar portion, and
• the planar portion and the fillet-shaped portion are formed of only smoothly curved surfaces without flat surfaces on the fillet-shaped portion side of the convex portion.
