A manufacturing adjustment system includes a decision part and a tolerance setting part. The decision part decides whether part dimensions calculated by a part dimension calculation part fall within a predetermined range of dimensions and a total machining time calculated by a total machining-time calculation part falls within a predetermined time. The tolerance setting part sets a workpiece tolerance for each machine based on the decision result of the decision part when the workpieces are produced by the machines.
