Preface
n recent years, the development of machinery manufacturing industry in China has been stable, and it has become one of the important pillar industries in China. However, there is still a certain gap between China’s machinery manufacturing technology and foreign manufacturing technology, which leads to the disadvantage of China’s manufacturing technology in the international competition. Therefore, to optimize the design of mechanical manufacturing process, the first consideration is the error control of manufacturing process; Secondly, we must fully implement the requirements of mechanical design and manufacturing, produce and manufacture in strict accordance with the design plan, and gradually improve the level of mechanical design on the basis of ensuring the rationality of mechanical manufacturing process. It is an important trend to improve the overall level of mechanical manufacturing by optimizing the design strategy to adapt to the growing material demand. At present, with the continuous improvement of national science and technology, the mechanical manufacturing process is also progressing. In mechanical manufacturing, mechanical design plays a very important role, which directly affects the performance and quality of finished products. Therefore, in mechanical design, rational design is very important, which has high technical requirements for materials and production specifications. This book discusses the needs of mechanical manufacturing process, takes mechanical rationalization as the goal, and optimizes the mechanical design appropriately, so as to effectively improve the rationality of mechanical manufacturing process.
前 言
近年来，机械制造产业在我国的发展一直保持平稳态势，同时也成为我国的重要支柱产业之一。然而我国机械制造工艺相较于国外制造技术还存在一定的差距，导致我国的制造工艺在国际竞争中处于劣势地位。为此，要对机械制造工艺进行优化设计，首先要考虑的就是制造过程的误差控制，其次必须全面落实机械设计和制造的工作要求，严格按照设计计划生产制造，同时要在保证机械制造工艺合理性的基础上，逐渐提升机械设计水平。而通过优化设计策略来提升机械制造整体水平，以适应不断增长的物质需求是当前发展的重要趋势。当前，国家的科学技术水平不断提高，使得机械制造工艺也不断进步，在机械制造中，机械设计发挥着非常重要的作用，直接影响到成品的性能和质量，所以在机械设计中，合理化设计是非常重
要的，其对材料与生产规范都有较高的技术要求，本书通过对机械制造工艺的需要做讨论，以机械合理化为目标，对机械的设计进行适当的优化，从而有效地提升机械制造工艺的合理程度。
