文档介绍：Overview 概观 A design engineer uses CAD (Computer Aided Design) software to create a part drawing, containing all features and dimensions required to manufacture a part. 设计工程师采用 CAD (计算机辅助设计)软件创建一个零件图,包含制造零件所需的所有功能和尺寸。 Computer Aided Manufacturing (CAM) evolved from the need to manufature using numerically controlled machine tool. Once CAD drawing plete, it can be imported into CAM software for further use. Using various functions withing the CAM software, the programmer selects various lines, circles, surfaces or other entities from the imported CAD drawing and then develops cutting sequences, or tool paths, that simulate actual machinig of those entities. 计算机辅助制造( CAM ) 从需要使用数控机床来 manufature 演变。一旦 CAD 图纸完成后, 它可以被导入到 CAM 软件继续使用。使用各种功能 withing 的 CAM 软件, 程序员选择不同的直线,圆, 表面或从导入 CAD 图纸等实体,然后开发切割序列或***路径,即模拟这些实体的实际 machinig 。 The most CAM applications, the tool path that is generated for each cutting sequence is placed into a file ina specific order and syntax, almost like a structured language. This file is called a Cutter Location Data (CLDATA) file. It contains mands, as well as X, Y,Z coordinate values, and in the case of four and five axes machines, will also contain tool vector I, J,K values used to determine the angle of the tool in relation to the part. 大多数 CAM 应用, 即对于每个切割序列生成的***路径被放入一个文件中的特定顺序和语法, 几乎像一个结构化的语言。此文件被称为刀位数据( CLDATA )文件。它包含各种命令,以及 X,Y,Z坐标值,并且在四和五轴机的情况下,也将包含 I,J,K 的值用来确定在相对于***的角***矢量部分。 Postprocessor reads each statement mand contained withing the CLDATA and postprocesses (translates) each of those statements mands C machine code. C machine code (G-Codes) is created based on the content of the CLDATA and bination with the settings in option file. 后置处理器读取每个语句或命令包含 withing 的 CLDATA 和后期处理(翻译)每个那些语句或命令到数控机床的代码。C 机器代码(G 代码) 是基于 CLDATA 的内容, 并与在选择文件中的设置的组合创建。 The Delcam PostProcessor application contains the following modules: The Postprocessor creates programs for C machine tool, in the form of tapefiles. The Editor is used to create or edit the option file, wh
