Preface
Machinery manufacturing industry is one of the most important sectors of the national economy. It can not only directly provide consumer goods for people’s life, but also provide technical equipment for all sectors of the national economy. It is an important foundation and pillar industry of national economy. Its development scale and level have a great restriction and direct influence on the development of national economy, and it is an important sign of a country’s economic strength and the level of scientific and technological development. Therefore, all countries in the world regard the development of machinery manufacturing industry as one of the strategic priorities for the revitalization and development of national economy.
The development and progress of machinery manufacturing industry, to a large extent, depends on the level and development of machinery manufacturing technology. Today, with the high development of science and technology, modern industry puts forward higher and higher requirements for machinery manufacturing technology, which promotes the continuous development of machinery manufacturing technology. At the same time, the development of cience and technology also provides opportunities and conditions for the development of machinery manufacturing technology. In particular, the development of computer technology makes it easier to combine conventional mechanical manufacturing technology with precision detection technology, numerical control technology, sensor technology, etc. It brings many new technologies and concepts to the field of mechanical manufacturing, and greatly improves product quality and production efficiency. The development of mechanical manufacturing technology has laid a solid foundation for the development of other high-tech and provided a reliable guarantee. Both of them promote each other and improve together, making a great contribution to the rapid development of society and economy.
In the process of compiling this book, we have read a large number of domestic and foreign textbooks, treatises and other documents. Due to the limited space, we will not list them one by one. We sincerely thank these authors of these documents. At the same time, due to the limited level and ability of editors, there are inevitably mistakes and omissions in the book. We sincerely hope that experts, scholars and readers can criticize and correct them, so as to further improve them in the future.
前 言
机械制造工业是国民经济最重要的部门之一，它不仅能直接提供人民生活所需的消费品，而且为国民经济各部门提供技术装备，是国民经济的重要基础和支柱产业，其发展规模和水平对国民经济的发展有很大的制约和直接的影响，是一个国家经济实力和科学技术发展水平的重要标志，因而世界各国均把发展机械制造工业作为振兴和发展国民经济的战略重点之一。
机械制造工业的发展和进步，在很大程度上取决于机械制造技术的水平和发展。 在科学技术高度发展的今天， 现代工业对机械制造技术提出了越来越高的要求，推动着机械制造技术向前不断发展，同时科学技术的发展也为机械制造技术的发展提供了机遇和条件。特别是计算机技术的发展，使得常规机械制造技术与精密检测技术、数控技术、传感技术等有机结合更易于进行，给机械制造领域带来许多新技术、新概念，使产品质量和生产效率大大提高。而机械制造技术的发展又为其他高新技术的发展打下了坚实的基础，提供了可靠的保证，两者互相促进，共同提高，为社会和经济的快速发展做出了极大的贡献。
