Regarding the product quality management system of our workshop, we know that in the production, no matter how sophisticated machinery and equipment, how skilled workers, the products produced can not be absolutely the same, and there are always certain differences in product quality (such as size, weight, composition, etc.). The reasons for the quality difference are many, but can be summarized into two categories: one is the normal causes, for example, the small vibration of the machine tool, the normal wear of the tool, the small loosening of the fixture, the small changes in the operation of the worker, the quality of the raw material of the same specification and the small changes in temperature and so on. This kind of reason is called accidental cause in mathematical statistics, and the quality variation caused by it can not be completely avoided in production, which is manifested as the difference within the tolerance limit. If we want to try to eliminate even part of it, it is necessary to make fundamental adjustments to the machinery and equipment or take other major measures to improve.
