Preface
Electrical automation is a significant symbol of industrial modernization as well as the core technology of modern advanced science, the development of electrical automation has a deep impact on the development of the national economy, this paper focuses on the importance of the development of electrical automation. The concept of electrical automation was proposed in the early last century, and related courses of electrical automation were offered in several colleges and universities in 1950s, indicating that the proposal and development of electrical automation in our nation is very earlier. As the rapid development of economy and the progress in science and technology, the electrical automation has been continuously improved and developed as well, especially , it has made vigorous development in recent years. The traditional concept of electric drive control can not match the production requirements of modern enterprise, so as to improve the production and management capabilities as well as the market competitiveness of enterprises, it’s important to enhance the application of current electric power automation component technology.
Nowadays, as the development of the technology, our nation’s electrical automation has made a great progress. In particular, the coming of information age and the widely application of new power electronic devices greatly improved the application of electric automation level of our country.
Machinery manufacturing and automation is a subject with great specialty and knowledge, by the introduction and application of automation technology, machinery manufacturing industry achieved the effective optimization of machining object production process as well as it’s continuous automatic production. The application and development of automation technology in manufacturing is a major means for machinery manufacturing industry’s technological transformation and development. And yet, the level of mechanical automation technology had a direct impact for the technological development of machinery manufacturing industry and national economic development sector. Thus, it’s necessary to study the mechanical manufacturing and automation.
前 言
电气自动化是工业现代化的重要标志和现代先进科学的核心技术、电气自动化的发展对国家经济发展有着极其远的影响、现着重闸述了电气自动化发展的重要性。我国早在上世纪初就已经提出了电气自动化的概念， 并且到了 50 年代， 在我国的各大高校中开始开设电气自动化的相关课程，因此我国的电气自动化的提出和发展是较早的。随着我国经济的高速发展和科学技术的进步，我国的电力电气自动化也得到不断地完善和发展，并且在近几年处在蓬勃发展的阶段，在电力电子技术和微电子信息技术领域取得了重大的进步，传统的电力拖动控制的概念已经不能适应现代企业的生产需要，所以为了提高现代电力的生产能力、管理水平和提高企业的市场竞争力，增强现在的电力电气自动化元件技术的应用，就显得尤为重要了。
近年来，随着科技水平的不断提升，我国电气自动化已经取得了较大的发展，尤其是信息时代的到来及新型电力电子器件的大量运用，促使我国电气自动化水平得到了极大的提升。
机械制造与自动化是一门专业性和知识性很强的学科，通过自动化技术的引入与应用，机械制造业实现加工对象地连续自动生产和生产过程的有效优化。自动化技术在制造的应用与发展，是机械制造业进行技术改造和技术发展的主要手段。而机械自动化技术水平的高低，对我国机械制造业和国民经济发展部门的技术进步与否产生了直接的影响。因此，有必要对机械制造与自动化进行研究。
