Preface

Mechanical manufacturing process refers to the method and process of using various mechanisms and appropriate production tools to process or process raw materials and semi-finished products, and finally convert them into mechanical products. There are more than 100 industries related to mechanical manufacturing technology, such as general machinery, machine tools and tools, mining, engineering machinery, metallurgy, rolling machinery, power generation equipment, petroleum, natural gas and chemical machinery, automobile and transportation machinery, etc. The development of mechanical manufacturing technology not only depends on the development of production, but also carries out experimental research. Through scientific methods, the process problems are analyzed, studied and solved, so that the level of technology can be improved. The development of mechanical manufacturing technology also promotes the innovation and development of equipment and process equipment such as knives, clamps, auxiliary tools and measuring tools. With the development of production and science and technology, many industrial sectors, especially national defense, aerospace, electronics and other industries, require products to develop in the direction of high precision, high speed, high power, high temperature resistance, high pressure resistance and miniaturization. The materials used in product parts are more and more difficult to process, the shape and structure are more and more complex, the required accuracy is higher and higher, and the surface roughness is smaller and smaller. The traditional machining methods can not meet the needs, so there are some precision machining and non-traditional machining methods. On the basis of expounding the common processes of mechanical manufacturing, this book studies the precision and non-traditional machining technology, and analyzes in detail the precision cutting of disk substrate, precision cutting of ceramic materials, laser processing, ultrasonic processing, electron beam processing, ion beam processing, etc.
      With the rapid development of modern science and technology, the diversity and variability of social needs, mechanical manufacturing must break through the original production organization mode, so that the product manufacturing can adapt to the changing market demand and fierce market competition. The combination of computer technology, numerical control technology, control theory, system engineering and manufacturing technology has produced modern manufacturing technology and formed modern mechanical manufacturing system. The automation of mechanical manufacturing system brings a series of benefits to modern mechanical manufacturing. This book focuses on the mechanical manufacturing system automation and computer-aided manufacturing technology are studied, in which the FMS automatic processing system is described in detail.

前 言

机械制造工艺是指采用各种机制、使用合适的生产器具加工或处理原材料、半成品，最终使之转换为机械产品的方法和过程。与机械制造工艺学有联系的行业有百多种，如通用机械，机床与工具，矿山、工程机械，冶金、轧制机械，发电设备，石油、天然气与化工机械，汽车与交通运输机械等等。机械制造工艺的发展不仅要依赖生产的发展，还要实施试验研究。通过科学的方法对工艺问题进行分析、研究与解决，使工艺水平得以提升。机械制造工艺的发展也促使了设备和刀、夹、辅和量具等工艺设备的革新与发展。随着生产和科学技术的发展，许多工业部门，尤其是国防、航天、电子等工业，要求产品向高精度、高速度、大功率、耐高温、耐高压、小型化等方向发展。产品零件所使用的材料越来越难加工，形状和结构越来越复杂，要求的精度越来越高，表面粗糙度越来越小。常用的传统加工方法已不能满足需要，于是，便创造和发展了一些精密加工和特种加工方法。本书在对机械制造常见工艺进行阐述的基础上，对精密与特种加工技术进行了研究，详细地分析了磁盘基片的精密切削、陶瓷材料的精密切削以及激光加工、超声波加工、电子束加工、离子束加工等。
         现代科学技术的飞速发展，社会需求的多样性和变化性，要求机械制造必须突破原有的生产组织模式， 使产品的制造适应日益变化的市场需求和激烈的市场竞争。计算机技术、数控技术、控制论及系统工程与制造技术的结合，产生了现代制造技术，形成了现代机械制造系统。而机械制造系统的自动化给现代机械制造带来了一系列的好处。本书重点对机械制造系统的自动化与计算机辅助制造技术进行了研究，其中对 FMS 自动加工系统进行了详细的阐述。
