Sinumerik 808D数控车床CNC和伺服系统连接与调试(含CAD图)(设计说明书12000字,CAD图纸7张)
摘要
随着机械生产技术水平的不断提升，对于机械生产的产品与质量都提出了更高的目标，加工工艺是保证上述进步的重要措施。工艺不仅能提高生产的效率，同时降低成本，还改善了工人的工作条件。数字型的机床因为这些因素慢慢诞生并发展壮大。
数字控制系统简称，英文名称为Numerical Control System，早期是与计算机并行发展演化的，用于控制自动化加工设备的，由电子管和继电器等硬件构成具有计算能力的专用控制器的称为硬件数控（Hard NC）。20世纪70年代以后，分离的硬件电子元件逐步由集成度更高的计算机处理器代替，称为计算机数控系统。
计算机数控（Computerized numerical control，简称CNC）系统是用计算机控制加工功能，实现数值控制的系统。CNC系统根据计算机存储器中存储的控制程序，执行部分或全部数值控制功能，并配有接口电路和伺服驱动装置，用于控制自动化加工设备的专用计算机系统。
CNC系统由数控程序存储装置（从早期的纸带到磁环，到磁带、磁盘到计算机通用的硬盘）、计算机控制主机（从专用计算机进化到PC体系结构的计算机）、可编程逻辑控制器（PLC）、主轴驱动装置和进给（伺服）驱动装置（包括检测装置）等组成。
由于逐步使用通用计算机，数控系统日趋具有了软件为主的色彩，又用PLC代替了传统的机床电器逻辑控制装置，使系统更小巧，其灵活性、通用性、可靠性更好，易于实现复杂的数控功能，使用、维护也方便，并具有与网络连接及进行远程通信的功能。

Abstract
With the improving of the mechanical manufacturing technology, mechanical products and quality are put forward for higher goals, processing technology is one of the important measures to ensure the progress. Technology can not only improve the efficiency of the production, at the same time reduce the cost, also improve the working conditions of the workers. Digital type machine because of these factors was born and grow slowly.
Digital Control System, the English name for Numerical Control System, is the early development evolution of parallel computer, is used to Control the automation processing equipment, the vacuum tube and relay hardware dedicated controller is capable of computing hardware called NC (Hard NC). Since the 1970 s, the separation of hardware electronic components gradually more integrated computer processor, called computer numerical control system.
CNC (Computerized numerical control, CNC) system is to use computer control processing functions, realizes the numerical control system. CNC system based on computer control program stored in memory, and perform some or all of the numerical control function, and is equipped with interface circuit and servo drive device, a special computer system for control of automated processing equipment.
CNC system by nc program storage device (from early paper tape to the circular, and magnetic tapes, disks, to general computer hard disk), computer control console (from a dedicated computer architecture evolution to the PC computer), programmable logic controller (PLC), spindle driver and feed (servo) drive (including detection device), etc.
Due to gradually use general computer, numerical control system is give priority to color with the software, and using PLC to replace the traditional machine tool electrical logic control device, make the system more compact, its flexibility, generality, better reliability, easy to implement complex numerical control function, operation and maintenance is convenient, and is connected to the network and the remote communication function.
This design is based on Siemens SINUMERIK 808 d numerical control lathe CNC and the servo system connection and debugging of design and research, the optimal speed control, shorten processing time, high production efficiency, processing is convenient, quick, quick installation, data processing, fast online diagnosis, shorten time, fast debugging tools: (1) the text manager and Windows PC - (2) IN PLC programming tool (3) servo debugging tools SimoCom, powerful PLC, parts processing program can backup on the PC card,
Rich user processing cycle (1) the turning circle (2) milling cycle (3) the drilling cycle integration step/servo drive control system,
Global services, the standard of PROFIBUS fieldbus communication, complete online training and information support programs to produce convenient and feasible - does not require any knowledge of numerical control, from simple to complex parts processing method
SINUMERK 808 d nc system were introduced in this paper the main composition, characteristics and applications. And the related contents in the control circuit design, and use the Programming Tool software development of the internal function of PLC system and related parameters setting, achieved the purpose of communication between the PC and digital control system, Siemens SINUMERIK 808 d milling version as controller commissioning of CNC lathe control contains system initialization, the use of PLC program, drive use, parameter setting, back to the CNC machine Tool reference point, etc.
