【正文】 外文翻譯 Post Builder Help Getting Started Post Builder creates and edits postprocessors. These postprocessors have three elements, each identified by the base name and one of three extensions. Assuming your postprocessor name is my_machine_tool, these files would be the following: Only Post Builder uses this file. This file contains static information on how to write out the .tcl file. Although Post does not need this file, it must be present in the same directory as the .tcl and .def files in order to edit your postprocessor. This file determines the blocks that need to be output from events that are generating by Post. This file uses the TCL language. Post Builder pletely creates this file every time you save your postprocessor. Post also uses this file at run time to generate NC code. This file defines all the static information for the postprocessor. This includes formats, address and NC blocks. The format of this file is a special syntax created by NX. This file is used by Post to postprocess the tool path and generate NC code. By default, Post Builder creates your postprocessor in the directory where you started Post Builder. Use the Save As option in the file dialog to save your postprocessor in the directory of your choice. In order to use your postprocessor in NX you must add an entry to your file in your current postprocessor directory. Post Builder supports English dialogs only. Procedures in the Base File NX Post depends heavily on procedures in the file. This file is located in the mach/postprocessor directory. The system uses it to support the file I/O and other basic functions. This is updated with each NX release, and should not be modified. It is possible to overwrite procedures in this file through tcl programming, but this is not remended. You can overwrite these procedures with a user created tcl file or by using the uplevel feature of tcl. When any of the procedures in are overwritten by the procedures in the postprocessor we no longer guarantee that the post will continue to work correctly from one release to the next. Some of the critical files that may cause problems when modified are: Creating a New Post To create a post follow the steps below: the New File icon or select New in the file drop down menu. You have the following choices from the Create New Postprocessor dialog: can select the name of your postprocessor or use the default name. You can change this name when saving. can enter a text description of your postprocessor. whether the system outputs in inch or metric. If you select inch, all coordinate output and formats are in inches. If you specify metric, all coordinate output is in millimeters. All of the default parameters such as tolerances, minimums and maximums are based upon the output units. See the section on Changing Postprocessor Kinematics for how to change from inch to metric or metric to inch after you have created the post. 5. Select a basic machine type. Once you have selected the machine type you can not change it again for this postprocessor. Your choices are explained in the following sections: Mill, Lathe, Wire EDM. Mill Selecting this option defines your machine as a mill type. The following mill types are available: 3Axis Your post has three linear axes ( X, Y and Z). 3Axis Mill Turn (XZC) Your post is the mill portion of a mill/turn. You can output standard Cartesian XYZ or output polar coordinates X (radius), Z and C(angle). See the Mill Turn section for more details. 4Axis with Rotary Table Your post has three linear axes (X, Y and Z) and rotary indexing or contouring table (A, B or C). 4Axis with Rotary Head Your post has three linear axes (X, Y and Z) and r
