Abstract: A surface treatment processing method includes: a shot processing step of performing shot processing of shooting shot media at a treatment target; a first inspection step of nondestructively inspecting at least one of a surface side state and an external dimension of the treatment target subjected to the shot processing, evaluating that the treatment target is passed when an inspection result is within a first normal range set in advance, evaluating that the treatment target is failed when the inspection result is out of a first allowable range set in advance to include the first normal range, and evaluating that the treatment target is to be additionally processed when the inspection result is out of the first normal range but within the first allowable range; and an additional processing step of performing the shot processing again on the treatment target which is evaluated to be additionally processed.

Abstract: A first inspection step nondestructively inspects a surface side state of a treatment target to be subjected to shot processing of shooting shot media at the treatment target and evaluates that the treatment target is failed when an inspection result deviates from a first allowable range predetermined. A condition setting step sets a shot processing condition in response to the inspection result of the first inspection step for the treatment target evaluated as not failed in the first inspection step. A shot processing step performs shot processing of shooting shot media at the treatment target evaluated as not failed in the first inspection step in the shot processing condition set in the condition setting step. A second inspection step after the shot processing step nondestructively inspects a surface side state of the treatment target.
