摘要: 针对使用非模态回转轴的双摆头五轴联动机床的转角在使用过程中受到局限的问题,提出一种基于后置处理的旋转角度优化算法。根据旋转角的转动范围确定初始修正条件,在保证刀具接触点坐标不变的情况下,采用分区域限制对修正区的旋转坐标值进行优化。通过运动学模型的建立,基于该类机床的基本后置处理算法,结合JAVA语言,开发出具有角度优化的专用后置处理器。某叶轮零件的仿真和实际加工结果表明,本算法能够对加工中旋转角进行修正,避免了由于结构原因造成的加工局限,从而提高了机床的使用范围,同时此法也为其他同类机床解决旋转角受限问题提供了一定的参考。

Abstract: A rotation angle optimized algorithm based on post processing is proposed to overcome the problem that rotation angle of rotary shaft is limited in the use of the double pendulum head five axis machine tool with the non modal rotary shaft. According to the rotation range of the rotation angle to determine the initial correction condition, in the case that the tool contact point is fixed, the rotation coordinates of the correction area are optimized. Through the establishment of the kinematic model, a special post processor with angle optimization is developed using java language based on the basic post processing algorithm of the machine tool. Simulation and practical processing of an impeller part using the algorithm are carried on. Results show that it could revise the rotation angle in the processing so as to improve the scope of machine tools for the processing limitation due to structural reasons is avoided. This method also provides a certain reference to solve the problem of limited rotation angle for other similar machine.
