C2-3003车床的数控化再制造研究（本科毕业论文设计）

摘要
电能是现代最常用且极为普遍的一种二次能源。电能具有许多优点，表现在：它的生产、传输、控制和使用都比较方便，且效率高，因而广泛用于工农业生产、交通运输、科学技术、信息传输及日常生活中，极大地推动了技术的进步和生产力的发展。
电机是与电能的生产、传输和使用又有着密切关系的电磁机构。例如：将自然界的一次能源如水能、热能、风能和原子能等转换为电能需要发电机，它是电厂的主要电气设备；为了经济地使用和分配电能需用变压器，它是电力系统的主要电气设备；在其他各行各业各部门都大量使用各种电动机作为原动机，用以拖动各种机械设备，这称为电力拖动；在军事、信息和各种自动控制系统中，则应用大量的控制电机，作为检测、执行和计算等元件；在医疗、文教和日常生活中，电机的应用也十分广泛。
随着电机及电力拖动技术的发展，其控制技术业发展迅速。特别是随着数控、电力电子、计算机及网络等技术的发展，电力拖动也正向自动控制系统------无触点控制系统、计算机控制系统迈进。
本次设计是机床电气工程及自动化、机电、应用电子技术等专业的一次综合设计。本次设计任务是培养学生掌握相关的基本理论，能借助计算机及相关软件来进行本次设计，最后既有较高的专业技术应用能力。

关键词：(二次能源，计算机网络技术，电力拖动，控制技术)

ABSTRACT

Energy is the most commonly used and common secondary energy in modern society.It has many advantages,performancing in the production,transmission,control and use are relatively easy,particular in its high efficiency.So,widely uesd in industrial and agricultural production,transportation,science and technology,information transmission and daily life.Great impetus to technological progress and the development of productive forces.
Electric power is an electromagnetic bodier which is closed with the production,transmission and use.For example:the nature of this energy such as water energy,geothermal energy,wind and nuclerr energy into electric energy needs generators,It’s the main electrical power plant equipment.In order to economic use and distribution of electric need transformer,It is the main electrical power system equipment.Other businesses and departments all large-scale use the motor as the original motivation.To drag all kinds of mechanical equipment,this is known as the electric drive;In the military,information and automated systems,the application of a large number of motor control,as a test,implementation and computing components;In health care,culture,education life,the motor is also very broad application.
With the electrical and electric drive technology development,their control technology industry has developed rapidly.Special in the wake of NC,power electronics,computer and network technology development,power forward also drag the automatic control system——non-contact control systems,computer control system.
This design is automated machine tools and electrical engineering,mechanical and electrical,electronic technology,and other professional applications of a comprehensive design.The design task is to train students to master the basic theories,use of computer and related software for this design,both the higher end of the porfessional and technical capabilities.

Key words:(Secondary energy ,computer network technology,electric drive,control technology)
