What is the significance of using this "three changes" in mechanical design?
Serialization refers to the same product, under the same basic structure or basic conditions, set out a number of different size seriesGeneralization refers to the parts and components of the same structure and size, which are used in different kinds of products or different specifications of similar products"Article three" the main benefits are: to reduce the design workload, improve design quality and shorten the production cycle; reducing tool and gauge specifications, easy to design and manufacture, thereby reducing the cost; for the organization of standard parts of the scale, specialization, to ensure product quality, material saving, cost reduction; improve interchangeability, easy maintenance; macro management and regulation for the country and in foreign trade; to facilitate evaluation of the quality of products, to solve the economic disputes.
Standardization refers to the products (especially parts) the quality, specifications, performance, technical index structure and other aspects of the unified regulations and standards to perform. As the standard of our country has already formed a huge system, there are national standards, industry standards and so on. In order to in line with international standards, some standards in China the rapidly move closer to international standards. The standard code such as GB, JB, ISO and so on, they are representative of the national standard of People's Republic of China machinery industry standards, the international organization for standardization standards.
Standardization is the design of things, do not have any significance of the difference, unified, become standard, is a reference, there are similar can rely on a standard. Like analog to digital conversion, the analog is transformed into a digital quantity that becomes discontinuous, but always satisfactory.Serialization is a product divided into different specifications, used in different needs, to find the corresponding level. It's like a dress. Tall, medium, and short people have to wear it. Products of the same function, the poor, the middle class and the rich, have their own affordable specifications.General purpose is interchangeable, easy to mass production, easy maintenance, once designed, can be used directly.The significance of standardization is to reduce unnecessary diversity.The significance of serialization is to form a routine, along the way, to sort out a category.The significance of generalization lies in the fact that similar situations are used directly and copied.
