TCL语言在FANUC数控系统UG后置处理中的应用

TCL Language and Its Application in FANUC CNC systems' Application of Post Builder in UG CAM

使用UG软件CAM模块生成数控加工刀轨后,需要经过后置处理转换成特定机床控制系统能识别的NC代码。特定数控系统后置处理的制作,需要使用TCL语言。NC程序中,注释项对NC程序的理解和管理都很重要,必要而规范的解释性语句不仅可以方便编程人员与机床操作人员的交流,而且方便不同人员对程序的理解。FANUC系统因为自身的特殊性,对一些符号、格式有独特的规定,本文结合FANUC数控系统常用的一些解释性语句,简要介绍了在制作机床后置处理时用到的一些TCL语句。

After the NC tool paths been generated by UG CAM module, it needs to be transformed into a NC program that can be identified by a specific CNC system after post processing. The production of post processing for a particular CNC system requires the use of TCL language. In the NC program, the annotation items are very important for the understanding and management of the NC program. The necessary and standardized interpretative statements can not only facilitate the communication between the programmers and the machine operators, but also facilitate the understanding of the program by the different personnel. FANUC CNC system has unique rules for some symbols and formats because of its own particularity. This paper briefly introduces some TCL statements used in the post processing of machine tools, combining some interpretative statements commonly used in the FANUC CNC system.
