Manipulator is now used as a industrial robots in use, the control objectives often appear often in industrial automation. Industrial automation technology has gradually matured, as mature a technology line has been rapid development in industrial automation as a separate subject. Manipulator application began to filter into welding, logistics, mechanical processing, and other industries. Especially at high or very low temperatures, full of poisonous gases, high radiation case, robot in similar circumstances showed great use also brings great convenience to the staff. Precisely because of this robot to get people's attention began to be a high degree of development. Labor rates, working conditions, labor intensive aspects of promoting development. Both at home and abroad to develop the PLC (programmable logic controller) is in various special circumstances and under special conditions set for mechanical devices. Now turned on the development of the microelectronics automatic control
technology and the rapid development of the trains, the success of PLC hardware software and simulation control win big and successful development, now continues to develop as a factory automation standards. Because robots are good development of the technology makes a good optimization of productive capital, and robot shows this unique advantages, such as: has good compatibility, wide availability, hardware is complete, and programming that can be mastered in a short time, so in the context of industrial PLC applications became ubiquitous. Manipulator in many developed country agriculture and industry has been applied, such as the use of mechanical harvesting large areas of farmland, repeated operations on the high-speed line that uses a robotic arm, and so on. Today, the high level of automation combined with restrictions on the manipulator development level is slightly lower than the international. The design is mainly arm welding machine by PLC Automation control.

manipulator control mode and programmable controllers introduction 2.1 Select discussion with manipulator control 2.1.1 classification of control relays and discrete electronic circuit can control old industrial equipment, but also more common. Mainly these two relatively cheap and you can meet the old-fashioned, simple (or simple) industrial equipment. So he can see them now, however these two control modes (relay and discrete electronic circuits) are these fatal flaws: (1) cannot adapt to the complex logic control, (2) only for the current project, the lack of compatibility and (3) not reforming the system with equipment improvements. Spring for the development of China's modern industrial automation technology the substantial increase in the level of industrial automation, completed the perfect relay of the computer too much. In terms of controlling the computer showed his two great advantages: (1) each of the hardware can be installed on one or more microprocessors; (2) the official
designer of the software writing content control is all about. Now in several ways in the context of industrial automation can often be seen in three ways: (1) Programmable Logical Controller (referred to as IPC); (2) Distributed Control System (DCS for short), and (3) the Programmable Logical Controller (PLC for short). 2.1.2 PLC and the IPC and DCS contrast contrast 1, each of the three technologies of origins and development requirements for fast data processing makes it invented the computer. The men brought in terms of hardware there, using a high level of standardization, can use more compatibility tools, is a rich software resources, especially the need for immediacy in operational systems. So the computer can effectively control is used to control and meet its speed, on the virtual model, real-time and in computational requirements. Distributed system started with a control system for industrial automatic instrument used to control, whereas now it is successfully developed into
industrial control computer used as a central collection and distribution system and transition of distributed control system in analogue handling, loop control, has begun to reflect the use of a huge advantage. Though distributed system has great advantages in loop regulation, but only as a means of continuous process control. Optimization of PLC is the corresponding relay needs was born, its main use in the work order control, early primary is replaced relay this hulking system, focused on the switch controlling the running order of functions. Marked by the microprocessor in the early 1970 of the 20th century emerged, micro-electronics technology has developed rapidly, people soon microelectronics processing technology will be used in the Programmable Logical Controller (that is

CAD/CAM 概念(广、狭义)和功能
CAD:工程技术人员以计算机为辅助工具来完成产品设计过程中的各项工作,如草图绘制、
零件设计、装配设计、工程分析等,并达到提高产品设计质量、缩短产品开发周期、降低产
品成本的目的。
CAM:广义:借助计算机来完成从生产准备到产品制造出来的过程中的各项活动,包括工
艺过程设计(CAPP)、工装设计、计算机辅助数控加工编程、生产作业计划、制造过程控制、
质量捡测与分析等。狭义:NC 程序编制,包括刀具路径规划、刀位文件生成,刀具轨迹仿
真及 NC 代码生成等。
CAPP 概念
从狭义的观点来看,CAPP 是完成工艺过程设计,输出工艺规程。但是在 CAD/CAM 集成系
统中,特别是并行工程工作模式,"PP"不再单纯理解为:Process Planning", 而应增加
"Production Planning"的涵义,这时,就产生 CAPP 的广义概念:即 CAPP 的一头向生产规划
最佳化及作业计划最佳化发展,作为 MRPⅡ的一个重要组成部分;CAPP 向另一头扩展能
够生成 NC 指令。

数据库的特点:数据库技术通过数据管理系统统一管理用户文件,能够解决数据冗余的
问题。另外它把用户观念的数据逻辑结构从整体逻辑结构中独立出来,在用户数据逻辑结构
与数据存储结构之间插入一层整体逻辑结构,使数据存储结构的变化不影响数据的 逻辑结
构和应用程序,从而解决了数据的独立性问题。
工程数据库是指能满足人们在工程活动中对数据处理要求的数据库。对于 CAD/CAM 系
