An object is to enable accurate machining by enabling shots to be accurately blasted on a workpiece even while workpiece is being deformed. A part manufacturing system includes: a peening device including a nozzle that projects a plurality of shots toward a workpiece, and a sensor that detects a distance to the workpiece; and a machining robot including a hand to which the peening device is attached, and a control unit that adjusts a position or an orientation of the peening device by controlling the hand based on the distance detected by the sensor.

Part manufacturing system and part manufacturing method

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.

Surface treatment processing method and surface treatment processing device

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.

Residual stress measuring device

A machine for centrifugally shooting abrasives that shoots the abrasives by rotation of an impeller is provided. In the machine, the impeller comprises a pair of disc-shaped side plates that face each other at a predetermined distance and a plurality of blades disposed between the side plates in the radial direction of the side plates. The impeller is mounted on a hub that is fitted into an output shaft of an electric motor. The impeller is covered by a cover. The side liner and blades of the machine can be easily replaced. A side linerthat is U-shaped with the longer side facing downward is detachably attached to the inner side of the cover. The upper part of the side liner is divisible into two parts. The side liner protects the side wall of the coverfrom the abrasives that are shot from the impeller. The side liner has a U-shaped cross section. The impelleris fixed to the hubby screwing a bolton the hubfrom the inner sides of the side plates. The diameter of the impelleris limited to be 200 mm at maximum.

Centrifugally projecting machine

A method and a device for easily setting a processing condition from a dent rate of a product by giving an arbitrary dent producing condition and a shotblast processing condition in a shotblasting process. The method calculates a processing time, a projection amount and a projection material speed for enabling a target dent rate to be set, from the number of dents in a predetermined dent unit area and time. The method comprises the steps of: calculating a dent unit area from a projection material hardness, a projection material particle size, a projection material speed and the hardness of a processed product; calculating the number of dents required to attain a predetermined target dent rate; and calculating a processing time from the number of dents, a projection amount, a projection material density and the projection material particle size.
