The three transfers of the world's manufacturing center in human history have confirmed the huge role of manufacturing in national economic prosperity. In recent decades, China's manufacturing industry has made great progress and has now become a major manufacturing country in the world, ranking among the best in the world in many aspects. On May 8, 2015, the State Council issued the "Made in China 2025" development plan, promoting the comprehensive transformation and upgrading of China's manufacturing industry. In order to achieve the strategic goal of becoming a manufacturing power, my country's manufacturing technology theoretical research and engineering practice need to be strengthened, such as tolerance engineering, one of the basic manufacturing technologies in the machinery industry.
What is tolerance engineering?
Tolerance engineering is a systematic engineering from analyzing design expectations to realizing the manufacturing process. It carries out a strict division of labor according to work functions, enables each functional module to establish a sound theoretical foundation, and defines the input, output and work content of each functional module (including the rules and methods of the three). At the same time, by establishing clear product development goals, we mobilize the resources of the four major development processes (design, process, measurement and assembly) to carry out highly collaborative, efficient and high-achievement operations, and ultimately achieve the expected product design goals. The logic diagram and flow chart of tolerance engineering are as follows:
Why is tolerance engineering needed?
In the entire process of mechanical manufacturing activities, the influencing factors of tolerances involve incoming materials, product design, process development, parts manufacturing, fixtures, equipment, measurement and environment, etc., and these influencing factors will also interact with each other, affecting the quality of the product at all times. Development cycle, development cost and development quality. Scientifically using tolerance engineering technology to manage the entire production process can allow companies to maintain the following advantages in a highly competitive environment:
1) Shorten the product development cycle.
2) Reduce product development costs.
3) Improve product manufacturing quality.
