由于DMU50 eVolution五轴加工机床具有高精度、高性价比,因此被广泛使用。然而机床工作台的B轴与机床的Y轴不重合,属于非正交结构,使得加工程序的后置处理相对困难。通过对双转台五轴机床开展结构分析,对任意刀具轨迹数据点,先求解出机床双转台的B轴和C轴后置处理转角大小,然后利用求解出的转角大小,通过坐标变换,求解出该刀具轨迹数据点对应的机床位置。利用后置处理算法开发了DMU50 eVolution五轴机床程序后置处理软件,该软件可将UG软件编制的加工程序转换为通用G代码程序。
The DMU50 eVolution five-axis machine tool is widely used due to its high accuracy and cost-effectiveness. However, the B axis of the machine tool table does not coincide with the Y axis of the machine tool, which belongs to the non-orthogonal structure, which makes the post processing of the machining program relatively difficult. Through the structural analysis of the dual turntable five-axis machine tool, for any tool path data point, the B-axis and C-axis post-processing corner size of the dual turntable of the machine tool are solved first, and then the coordinate transformation is used to solve the corner size The tool path data point corresponds to the machine position. The post-processing software of DMU50 eVolution five-axis machine tool program was developed by using the post-processing algorithm. The software can convert the machining program compiled by UG software into a universal G code program.
