【摘要】 五轴后置处理是将CAM软件系统产生的刀位文件转换成数控机床加工程序的关键环节。基于五轴后置处理过程中转角选解、优化以及奇异区域加工数据处理的问题,提出了一种集合转角选解、优化及奇异区域处理的方法,解决了因后置处理中选解不当引起的碰撞、旋转轴在相邻刀位之间摆幅过大以及在奇异区域旋转轴产生急速转动、非线性误差过大等问题。该方法应用C++语言开发了相应的后置处理系统,通过读取CATIA刀位文件,生成可执行数控加工程序,经Vericut仿真验证该算法可行。更多还原

【Abstract】 Post-processing is the key of the transformation from CL-Data of CAM system to NC program. Since the improper selection of rotation angle will leads to collision between cutter tool and work piece and dramatic change of rotary axis in adjacent cutter-location as well as rotary angle changes rapidly and non-linear error exceeds allowable limits in singular area. This paper proposed a method which integrates optimization of rotation angle and singular handling in five-axis post-processing. A post-processor was developed with C++ program language based on the method, which inputs the CL-Data of CATIA NC manufacturing module and outputs the NC program. The validity of the method is verified through Vericut simulation.更多还原
