The postprocessing technique is an important field in the UG CAM, The main mission is to make the cutter location source file that is created by CAM the acceptable numeric control document. 后处理技术是UGCAM中一个重要环节,其主要任务是把CAM软件生成的加工刀位源文件转换成机床可接受的数控代码文件。
The cutter location source file of UG was studied, using UG/ Open Grip, the useful processor was designed for Huazhong Numerical Control System ( HNC-21M). 通过对UG刀位文件格式进行研究,使用UG二次开发工具UG/OpenGrip,以华中数控系统HNC-21M为对象,设计了该数控系统具有实用价值的专用后置处理器。
At last, the paper studied the CAM application technologies, directly created 3D model, including the creation method of cutter location file directly from the 3D model, the NC post processing, etc. 最后,探讨了从三维产品模型直接生成刀位源文件,并进行数控加工的CAM技术的实现,生成数控加工刀位源文件和NC加工后置处理程序;
The post processing is an important part in the programming of numerical control, by using it, the cutter location file from CAM system can be converted into machining code. 后置处理是数控编程的重要环节,它的作用是将CAM系统生成的刀轨文件转化为机床的加工代码。
After studying the feasibility of translating NC codes into cutter's location file, this article exploits NC translator which includes several modules, namely file reading and save, mistake analysis and verbal meaning analysis, translation performance, data contrail simulation and so on. 该文在对NC代码翻译成刀位文件的可行性进行研究后,开发出了NC翻译器。翻译器共分以下几个模块:文件的读入与存储、错误分析与语义分析、翻译执行、数据轨迹仿真等。
Process step-step decision-making module for the content of design work to determine the cutting, NC machining to provide control instructions to form the required cutter location file; ( 6) NC machining instructions generated modules. 工步决策模块对工步内容进行设计,确定切削用量,提供形成NC加工控制指令所需的刀位文件;(6)NC加工指令生成模块。
NC machining process step instruction generation module based decision-making module provides the cutter location file, call the NC command code system, resulting in control NC machining instructions; ( 7) output module. NC加工指令生成模块依据工步决策模块所提供的刀位文件,调用NC指令代码系统,产生NC加工控制指令;(7)输出模块。
The NC processing software deals with how to apply existent NC codes or CLSF ( Cutter Location Source File) to the test bench, while the user-interface software how to realize the function of man-machine conversation. 数控处理软件主要是实现如何利用现成酌NC代码或刀位文件在机床上实现加工;用户界面软件主要是人机对话功能的实现。
