Preface

In today’s rapid development of science and technology, CNC machining has become one of the main methods of machining, CNC machine tools have become a major machine of machining. It not only has the characteristics of traditional machine tools, but also increases the numerical control function, which largely releases the hands of workers, reduces the burden of workers, and improves the quality of the processed workpiece. It is an essential processing equipment in the future mechanical processing industry.
        Mold is the main process equipment of industrial production, mold industry is the basic industry of national economy. With the rapid development of industry, mold manufacturing industry is required to provide efficient, precise and long-life molds for the development and production of new products in the shortest possible time. In order to meet this requirement, mold processing technology must enter a new stage of NC machining and mold CAD. Mold is the basic process equipment of manufacturing industry, and it is also one of the main process equipment of modern industrial production, which is widely used in various fields of manufacturing industry. The development of modern industry and the improvement of technical level largely depend on the development level of mold industry. Many new technologies and new equipment are often produced and applied in the mold industry. Undoubtedly, the mold industry is one of the main application fields of advanced manufacturing technology. Mold manufacturing technology level represents the development level of a country's manufacturing technology. With the continuous development of China’s manufacturing industry, mold manufacturing is becoming more and more important.
         This book is based on the actual processing technology of CNC machine tools, with the direction of typical factory CNC mold processing, combined with the actual CNC processing flow, introduces the knowledge, but also interspersed with various examples.This book makes the knowledge come from practice and apply to practice. It perfectly combines practical operation with book knowledge, that is, to realize the combination of theory and practical application. To a certain extent, it enhances the ability of scholars to get started, and really makes them easy to learn and use.

前 言

在科技飞速发展的今天，数控加工已经成为机械加工的主要方法之一，数控机床也成为当下机械加工的一种主要机器，它不仅有传统机床的特点，同时增加了数控功能，很大程度上释放了工人的双手，减轻了工人负担，还提高了被加工工件的质量，是未来机械加工行业必不可少的加工设备。
       模具是工业生产的主要工艺装备，模具工业是国民经济的基础工业。随着工业的高速发展，要求模具制造业在尽可能短的时间内，为新产品的开发和投产，提供高效、精密、长寿命的模具。为了适应这一要求，模具加工技术必须进入数控加工和模具计算机辅助设计的新阶段。模具是制造业的基础工艺装备，也是现代工业生产的主要工艺装备之一，被广泛应用于制造业的各个领域。现代工业的发展和技术水平的提高，很大程度上取决于模具工业的发展水平。许多新技术和新设备的产生与应用往往源于模具工业，无疑模具行业是先进制造技术的主要应用领域之一。模具制造技术水平代表了一个国家制造技术的发展水平，在我国制造业不断发展，所以模具制造也越来越重要。
       本书是以数控机床的实际加工工艺为基础，以工厂典型数控模具加工为方向，结合实际的数控加工流程，介绍知识的同时也穿插着各种实例，做到了知识来源于实际，应用于实际，将实际操作和书本知识完美结合，也即实现理论和实际应用的结合，从一定程度上增强了学者的上手能力，真正做到即学即用得心应手。
