A processing machine (10) for building a built part (11) includes a support device (14), a drive device (16), a powder supply device (20), and an irradiation device (24). The support device (14) includes a support surface (14A). The drive device (16) moves the support surface (14A) so that a specific position on the support surface (14A) is moved in a moving direction (30). The powder supply device (20) supplies a powder (12) to the support device (14) to form a powder layer (13). The irradiation device (24) irradiates at least a portion of the powder layer (13) with an energy beam (232) to form at least a portion of the built part (11) from the powder layer (13). Additionally, the irradiation device (24) changes an irradiation position where the energy beam (232) is irradiated to the powder layer (13) along a circumferential direction about an optical axis (234) of the irradiation device (24).
