METHOD FOR MANUFACTURING MACHINED PART, AND MACHINED PART

摘要

[Task] To provide a method that makes it possible to easily, inexpensively and accurately manufacture a machined part with a simple configuration and an excellent strength.;[Means for Solution] In a method for manufacturing a machined part according to the invention, a dislocation is partially introduced (S3), through shot peening, only into a surface layer of a raw material 1 in a region 1a to be machined, graphite is partially deposited (S4), through heating, only in the surface layer of the region 1a to be machined, and then, the surface layer of the region 1a where graphite is deposited is removed, through machining (S5), only by an amount corresponding to a working margin 1c, thereby manufacturing a machined part 1′.

主权项

1. A method for manufacturing a machined part by cutting and removing a predetermined region of a raw material through machining, comprising:
introducing a dislocation only into the region to be cut and removed after the raw material, before carrying out the machining, depositing graphite only in the region through heating, and cutting and removing the region where the graphite is deposited.
