1:外文资料翻译译文一般定位误差补偿定位误差补偿简介控制器制造商提供一种能够让你通过已经载入说明书的机床各轴补偿值把任何误差从机床定位系统中消除。直线度定位误差和回转度定位误差可以被补偿。通过应用补偿你可以减少诸如几乎彻底无意义的和机床精度被相当地程度改善的误差。同时这是一种非常优秀的概念,你必须知道在获得误差补偿值前,你必须先能够测量在一个轴上许多不同的点的移动部分的预期位置和他的实际位置之间的微小距离。幸运的是有一种方法已经存在:综合使用 Renishaw 激光干涉仪系统和定位误差补偿软件补偿包。需要被测量的误差可能被认为很小,小到只有微米乃至更小。然而,一个轴上的累积误差的影响是相当大的。利用激光去测量这些误差和利用补偿软件去记录误差,一张在轴上各点测量误差表格能够很容易被获得。这些误差能够然后转化为控制器能应用移动部分沿轴离开补偿值。Renishaw 定位误差补软件对标准的 Renishaw Laser10 校准软件提供附加的选项。软件提供一种“一步接一步”的用户界面去指导你通过误差补偿程序中各种不同的阶段。怎样对一台机床进行补偿对机床进行补偿,你使用能够提供定位误差补偿的软件去为控制器编辑一些程序的设备。这是个简单的任务,你所需要做的是指定在轴上你想要测量的直线度误差的目标位置和软件编辑的程序将自动为你标出。串行通信设备是常使用来传递程序进入控制器的。一旦那样以后,你将电脑设成数据捕捉模式并开启程序。移动部件的位置是软件通过激光干涉仪监控的。当控制器停在各个目标位置时,也就是在适当的停留阶段,在他移动到下一个目标位置前,移动部件的位置将被软件捕捉。这个连续循环将在所有目标位置在要求顺序下访问后停止。数据采集程序因此是完全自动的;所有你所需要做的是观察它。在捕捉完数据后,你能够分析它在沿轴方向上的直线度位置误差。这是通过标准数据分析执行的,而不是设备附加软件包。如果你认为补偿是需要的话,你需指定轴上部分需要为直线度误差补偿的起始点和终结点。同时需指出一系列你要求的补偿值和在每个连续补偿点间的距离。软件将计算出误差补偿值。之后你就能将这些输入到控制器中,或者通过使用控制器 6 手工输入,或者使用串行通信设备自动输入。你之后应该检查控制器应用的补偿符合你的公差要求。做好后,再次运行你的所编的程序并采集数据。如果在分析完补偿数据后,你仍想要进一步的降低误差,你可以在直线度误差已经被测量的轴上增加目标位置,并开始运行新的一段程序。另一方面,如果你对补偿结果满意,你应该让控制器多次运行。通常是 5 次,每次运行时移动部件移动到一系列随机的目标位置。通过这样,你能够照某一可适用的国家标准或诸如 ISO230-2 的国际标准获得数据。在数据采集之后,在各目标位置的误差测量将被存储在一个数据文件。因此它可能维持以前在一个轴上的误差记录和被应用之后的补偿。这些数据文件能够被复制到软盘为了确保安全而存档,成为将来的参考资料。如果因为任何理由,存储在控制器的误差值将变不可靠的在稍后一段时间,你能够通过转移包含在一些数据文件里的数据很容易恢复它们。软、硬件要求为了使用由位置误差补偿软件包提供的工具,你必须使用以下内容:一个 IBM 个人计算机或者一个配备有至少 32 兆的随机存储器,一个连续通讯端口,一个具有 SVGA 风格的监视器的兼容计算机。软件不支持单色显示器。硬盘是基本的,软件使用许多大文件夹,在执行误差补偿期间,你将创造几个新的文件。如果你是使用 Renishaw ML10 激光仪,连接电脑到激光仪 PC10 控制卡片,必须合适。软件也能够被用来和 Renishaw 硬件和其他激光仪搭配使用。RS232 串行通信电缆是用来连接电脑到你控制器上的数据登记项端口。注意:一些个人计算机使用标准 25 通道 D 型连接器同时使用自动实验系统和手提式计算机一般使用 9 通道连接器。RS232 电缆连接需要管理员对误差补偿使用者操纵控制器界面需求主题熟悉。Renishaw ML10 或者类似的激光仪,三脚架和线性光学。Windows 95,Windows 98 或者 Windows NT4 或更先进的计算机。标准的 Renishaw 线性数据捕抓和分析软件。已经连接的装备如下图 1 所示:选项2 个可选择的装置选项可能曾用于测量线性度误差的任务。他们是:EC10 环境补偿单元,打印机。EC10 环境补偿单元允许软件对连续地并且自动地对变化着的影响通过激光束传递的空气折射指数的环境参数进行补偿。如果不使用这,环境参数(空气温度和材料温度,湿度和气压)必须人工输入。这是有用的但并非强制需要一个打印机获得在误差补差运行过程的不同阶段的数据复制。例如,对于软件生成的一些数据文件夹能够被打印出和检查,也许能找出控制器现在的配置,或者也许检查一个显示在补偿之前与之后的线性度误差的曲线。如果打印机是可用的,这种类型的数据能够在执行其他任务的同时被打印出和检查。误差补偿包一般情况软件必须执行自动定位误差补偿对于标准 Renishaw Laser10 校准软件是一个附加软件包。因为控制器用不同方法操作,就有一种软件包对应一种控制器类型。例如他们在部分程序中说明不同地机床参数和使用不同的惯例。为了在一个有特殊控制器类型的机床上执行定位误差补偿,你必须先安装适用控制器的软件。其后,但你开始执行来自于 Renishaw 程序组的定位误差补偿软件,你能够因而选择你机床控制器的选项。软件需要执行定位误差补偿的软件是由 CD-ROM 提供的。请注意每一个控制器模型具有一个单独的 CD-ROM。每个 CD-ROM 包含“一般”误差补偿软件成分和特定成分以支持特殊的控制器类型。安装软件安装是通过执行“安装”键。该程序复制 CD-ROM 的文件到你计算机硬盘的目录里。这个目录是引述 Renishaw 目录。至于安装程序的详细资料,查阅在线使用导向软件安装主题。其他需要的文件机床定义文件除此特殊控制器类型的软件之外,另外的文件叫做机床定义文件(MDF)被安装。这个文件对于 RS232 包含部分程序模版和默认设置界面。机床定义文件被赋予使用关联控制器软件相同的名字。例如:MAZAK,MDF 是为 Mzaak M-Plus,M32 和 M2 系列控制器的机床定义文件。配置文件CURRENT.RCF 文件包含当前配置信息,它是使用 WINCAPT.EXE 捕捉软件和GEC.EXE 误差补偿软件。这个是一个由 Renishaw 提供的缺省名文件,另外 RCF 文件能够通过在文件夹中使用不同名字改变配置和存储而被创造出。语言文件诸如 ENGLISH.WLE,FRANCH.WLE 和 DEUTSCH.WLE 文件包含菜单正文,对话框,帮助文件和错误信息,是使用 WINCAPT.EXE 和 WINANAL.EXE 捕捉分析软件。类似的,诸如 GECE.WLF,GECF.WLF 和 GECD.WLF 文件包含菜单正文,对话框,帮助文件和错误信息,是使用 GEC.EXE 误差补偿软件。误差补偿设备定位误差补偿软件提供的设备,附加于 Laser10 的校准软件,能使你测量沿机床一个轴上定位误差。一旦误差被测量,软件通过产生一系列的补偿值对其清零补偿。这些补偿值直接被传输到控制器。这样在机床轴上的误差能够被补偿。通过在其他轴上重复程序,整个机床能够被补偿。定位误差软件能够使你执行下列东西:为控制器创造一部分程序。这样的程序指示机床移动到指沿轴定点并停留几秒钟同时校准软件测量位置误差。自动地测量移动部件相对于参考位置的位置,在每个端点指定部分程序,并为之后的误差分析储存这些读数。为控制器编辑一些误差补偿值,在移动部件实际位置(被激光干涉仪系统所测量)和理论的控制器起始位置。通过经 RS232 连接传送用新设置的值代替控制器中存在的误差补偿值。储存误差补偿值因而他们能够通过随机数据分析软件检测。浏览,编辑,打印各类数据和配置文件。使用简单的通信设备访问控制器。数据文件类型创造一个包括建立,获取和维护各类数据,以及沿着机床轴线测量各点错误的程序是应该被重视的。数据以文件形式被保存在电脑的硬盘上。因为数据的多样性,被存为多种文件格式,并以他们的扩展名来识别。 例如,文件名句点后的三个字符。6 种使用下列扩展名的文件被广泛应用。RPP Renishaw 部分程序文件通常,这是由位置误差补偿软件创建的,但是,你也可以用文字编辑器创建自己的文件。它包括指示控制器移动机床移动部件的命令。补偿软件可自动创建部分程序使移动部件在不同的点沿着一指定轴线安置。因此,使软件可以在这些点上测量位置误差。创建部分程序非常简单,因为你不需要知道控制器用来安置移动部件的特定命令和进给值。如果有必要,你可以创建和保留一个部分程序当机床被补偿时得到的数据库,这样,你可以比较在一定时间内的结果。一旦 RPP文件被建立,他就可以通过 RS232 通信链接被发送,并在任何地方运行被选择的控制器。RTL 线性数据文件这个文件是在激光校准软件捕获到数据时创建的。它包括当控制器停止机床移动部分的一系列位置(例如目标), 之后, 在目标位置和实际位置之间的误差将被测量出来。在这类文件中包含的数据实质上是当机床某一轴补偿时测到的误差的记录。如果几条轴在同一时间补偿,每一条轴都会产生一个 RTL 文件。建议在补偿好一条轴或者机床的所有轴之后,把 RTL 文件复制到软盘上。并把软盘保存在安全地方,以防以后再次查阅。OMP 原始机床参数文件这个文件是由误差补偿软件建立的. 所包含的数据从机床控制器通过 RS232通信链接下载获得。由软盘转移或者手动输入。下载是首选方法,但是实际上要取决于控制器支持什么。(例如, 一些控制器不支持 RS232 通信链接)。文件保存当前控制器机床参数的数值。如果,在之前一个轴被补偿,文件也可以保存当前控制器使用的补偿值。如果轴没被补偿,补偿值为零。OPM 数据明确为一台机器。并且一般只需要生成一次。文件被存在电脑硬盘上,在之后的误差补偿时可能再次被使用。TBL 轴的表格文件 (误差补偿时的文件)此文件由误差补偿软件创建,并包含每一个补偿轴的信息。信息包括用来定义被补偿部分的极限, 及在这些极限之间计算出的错误补偿值。它还包括机床所用的 NMP 文件的详细资料, 这还能够使任何存在的补偿时段继续。总之,它提供了一个关于轴如何被调整的概要。NMP 新机床参数文件当一个或多个机床轴被补偿时则创立此文件。NMP 文件被误差补偿软件用来储存需要和新补偿值一起变动的机床参数值,在软件计算完每一个轴之后。MDF 机床定义文件这个文件由 Renishaw 创建,包含各式针对某一特定控制器的数据。数据识别当一个部分程序被建立时,某些延伸设备和控制器的特定命令默认值。所有这些文件储存为 ASCII 格式,因此可用任何文本编辑器和文字处理器读出和打印。因为这些文件是基于文字,它们也可以被修改编辑。但是,除了 RPP或者 MDF 文件,他们应该没有必要修改。如果修改的话,结果会搞乱软件。当修改 RPP 文件时,你应该十分了解控制器从部分程序读取的命令,否则,当运行的时候,控制器可能执行意料之外的动作。在大多数情况下,MDF 文件只有 2 个你可能需要修改的部分。其一包括用来让RS232 通信链接控制器的默认设置。有经验的使用者可能会想修改 MDF 文件的第二个部分,包含软件用来创建部分程序的模板信息。当编辑这个部分的时候, 你可以添加特定的控制器命令 (G 代码),可根据你的需要设置控制器。参考自定义机床定义文件主题寻求更多信息。然后,你并不需要编辑这些文件,除非你对控制器的命令和功能工作完全熟悉 (例如它的 G 代码)。附件 2:外文原文About positioning error compensationController manufacturers provide a facility which allows you to remove any errors in the machine positioning system by specifying compensation values for each machine axis. Both linear and rotary positioning errors may be compensated. By applying compensation you can reduce errors to such an extent that they are almost completely nulled and the accuracy of the machine is improved considerably.Whilst this is an excellent concept, it must be understood that to obtain error compensation values, you must first be able to measure the small differences between the intended position of the moving part and its actual position, at various points along an axis. Fortunately a solution already exists; the combined use of a Renishaw laser interferometer system and the positioning error compensation software extension package.The errors that need to be measured may be considered to be small, in the order of a micrometre or so, however, the cumulative effect of such an error along an axis can be quite considerable. Using the laser to measure these errors and the compensation software to record them, a table of measured errors at points along an axis can easily be obtained. These errors can then be translated into compensation values which the controller can apply as the moving part is moved along the axis.The Renishaw positioning error compensation software is offered as an additional option to the standard Renishaw Laser10 calibration software. The software provides a step-by-step user interface to guide you through the various stages of the error compensation procedure.How a machine is compensatedTo compensate a machine, you use the facilities provided by the positioning error compensation software to create a part program for the controller. This is a simple task; all you need to do is specify the target positions along the axis where you want to measure the linear error and the software creates the part program for you automatically.Serial communication facilities are then used to transfer the part program into the controller. Once it is there, you set the computer into its data capture mode and start the part program.The position of the moving part is monitored by the software via the laser interferometer. As the controller pauses at each target, the position of the moving part is captured by the software, during a suitable dwell period, before it is moved on to the next target. This cycle continues until all targets are visited in the required sequence. The data gathering process is therefore totally automatic; all you need to do is to observe it.After capturing the data, you can analyse it to see the linear positioning error along the axis. This is performed using the standard data analysis software rather than facilities in this additional package.If you then decide that compensation is required, you specify start and end points which define the part of the axis you want to compensate for linear errors, and either the number of compensation values you require or the distance between each consecutive compensation point. The software then calculates the error compensation values. You can then enter these into the controller either manually, by using the controllers data entry keys, or automatically, by using the serial communication facilities.You should then check that the compensation applied by the controller meets your tolerance requirements. To do this, you run the part program and capture the data again. If, after analysing the compensated data, you want to reduce the errors further still, you can increase the number of targets at which linear errors are measured and start again by producing a new part program.Alternatively, if you are satisfied with the compensation, you should instruct the controller to perform several runs, usually five, where the moving part is moved to a number of random targets in each run. By doing this, you can obtain data which complies with one of the applicable national or international standards such as ISO 230-2.After a data capture session, the errors measured at each target can be stored in a data file. It is therefore possible to maintain a record of errors in an axis before and after compensation has been applied. These data files can be copied to a floppy disk and archived for security and future reference. If, for any reason, the compensation values stored in the controller become corrupted at a later date, you can easily restore them by transferring the data contained in some of the data files.RequirementsIn order to use the facilities provided by the positioning error compensation software package, you must use the following: An IBM PC or compatible computer with at least 32 Mb of RAM, one serial communication port, and a SVGA colour monitor. The software does not support monochrome displays. A hard disk is essential; the software uses a number of large files and, during the course of performing error compensation, you will be creating several new files. If you are using the Renishaw ML10 laser, the PC10 control card, for connecting the computer to the laser, must be fitted. The software can also be used with other Renishaw hardware and other lasers. An RS232 serial communication cable for connecting the computer to the data entry port on your controller. Note: Some PCs use the standard 25-way D-type connector whilst ATs and portables generally use a 9-way connector. The RS232 cable connections required for your controller are detailed in the Interface Requirements topic of the error compensation user guide for the controller. The Renishaw ML10 or similar laser, tripod and linear optics. Windows 95, Windows 98 or Windows NT4 or above. The standard Renishaw linear data capture and analysis software. This equipment is interconnected as shown in Figure 1 below:Figure 1 - System interconnectionsOptionsTwo optional items of equipment may be used to aid the task of measuring linear errors. These are: An EC10 environmental compensation unit A printer The EC10 environmental compensation unit allows the software to continually and automatically compensate for variations in environmental parameters that affect the refractive index of the air through which the laser beam passes. If this is not used, environmental parameters (air and material temperature, humidity and air pressure) must be entered manually.It is useful but not mandatory to have a printer to obtain hard copy of data at various stages during an error compensation run. For example, some of the data files produced by the software can be printed out and examined, perhaps to find out how the controller is currently configured, or perhaps to examine a graph which shows the linear errors before and after compensation. If a printer is available, this type of data can be printed and examined whilst the computer is performing another task.Error compensation packageGeneralThe software required to perform automatic positioning error compensation is provided as an additional software package to the standard Renishaw Laser10 calibration software. Because controllers operate in different ways, i.e. they interpret machine parameters differently and use different conventions in their part programs, there is one software package for each type of controller.In order to perform positioning error compensation on a machine with a particular type of controller, you must first install the software for that controller. Thereafter, when you start the positioning error compensation software from the Renishaw program group, you can then select the option for your machines controller.SoftwareThe software required to carry out positioning error compensation is supplied on CD-ROM.Please note that there is a separate CD-ROM for each model of controller. Each CD-ROM contains generic error compensation software components and also specific components to support the particular model of controller.Installing the softwareInstallation is performed by using setup. This program copies the files from the CD-ROM into a directory on your computers hard disk. This directory is termed the RENISHAW directory.For details of the installation procedure, refer to the Software installation topic of the on-line user guide.Other files requiredMachine definition fileIn addition to the software for your particular type of controller, another file called a machine definition file (MDF) is installed. This file contains a part program template and the default settings for the RS232 interface. The MDF file is given the same name as the associated controller software that uses it.For example:MAZAK.MDF is the MDF file for Mazak M-Plus, M32 and M2 series controllers.Configuration fileThe CURRENT.RCF file contains current configuration information and is used by the capture software WINCAPT.EXE and by the error compensation software GEC.EXE. This is the default name for the file as supplied by Renishaw but other RCF files can be created by changing the configuration and saving it in a file with a different name.Language filesFiles such as ENGLISH.WLE, FRENCH.WLE and DEUTSCH.WLE contain the text for the menus, dialog boxes and help and error messages used by the capture and analysis software WINCAPT.EXE and WINANAL.EXE.Similarly, files such as GECE.WLF, GECF.WLF and GECD.WLF contain the text for the menus, dialog boxes and help and error messages used by the error compensation software GEC.EXE.Error compensation software facilitiesThe positioning error compensation software provides facilities, additional to the Laser10 calibration software, that enable you to measure the positioning errors along an axis of a machine. Once the errors have been measured, the software nulls them by generating a table of compensation values. These values are then transmitted directly into the controller. In this way, the errors in one machine axis can be compensated. By repeating the process on the other axes, a complete machine can be compensated.The positioning error compensation software enables you to perform the following: Create a part program for the controller. Such a program instructs the machine to move to selected points along an axis and pause for a few seconds whilst the calibration software measures the positioning error. Automatically measure the position of the moving part relative to its reference position, at each of the points specified in the part program, and store these readings for error analysis later. Compile a table of error compensation values for the controller, to null out the difference between the actual position of the moving part (measured by the laser interferometer system) and the theoretical controller derived position. Replace the existing error compensation values in the controller with the new set of values by sending them via an RS232 link. Store the error compensation values so that they can be examined by optional data analysis software. View, edit and print various data and configuration files. Use simple communications facilities to interrogate the controller. Data file typesIt should be appreciated that creating a part program and measuring the error at various points along the axis of a machine involves the creation, capture and maintenance of a variety of data. This data is held in files which are stored on the computer hard disk. Due to the variety of data used, it is stored in several files, each being identified by the extension to its name, i.e. the three characters that follow the full-stop separator after the filename. Six types of file with the following extensions are used: RPP Renishaw part program file This is normally created by the positioning error compensation software but you can create your own using a text editor. It contains the commands that instruct the controller to move the machine moving part. Part programs created automatically by the compensation software are used to position the moving part at various points along a particular axis, hence allowing the software to measure the positioning error at those points. It is very easy to create a part program because you do not need to know the specific commands that the controller uses to position the moving part or change its feed rate. If necessary though, you can create and retain a library of part programs for use whenever a machine is compensated, allowing you to compare results over a period of time. Once an RPP file has been produced, it can be transmitted, via an RS232 communications link, to a controller where it can be selected and run. RTL Linear data file This is created by the laser calibration software during data capture. It contains a list of positions where the controller stops the moving part of the machine (i.e. the targets), and the error that was measured between each of these target positions and the actual position of the moving part. The data contained in this type of file is essentially a record of the errors measured when an axis of a machine is compensated. If several axes are compensated in one session, an RTL file is produced for each axis. It is recommended that RTL files are copied to a floppy disk after compensating an axis or all axes of a machine. This disk should be stored away in a safe place in case the data needs to be referred to at a later date. OMP Original machine parameters file This file is created by the error compensation software. The data it contains can be obtained by downloading it from the machine controller via an RS232 communications link, transferring it by floppy disk or entering it manually. Downloading is the preferred method but the actual method used depends upon what the controller supports (e.g some controllers dont support an RS232 link). The file holds the current values of the controller machine parameters. If an axis has been compensated on a previous occasion, the file also holds the compensation values that are currently being applied by the controller. If an axis has not been compensated, the compensation values are zero. The OMP data is specific to a machine and normally should only need to be generated once. The file is held on the computer hard disk and may be recalled at subsequent error compensation sessions. TBL Axis table file (error compensation session file) This file is created by the error compensation software and contains information about each compensated axis.
