针对数控系统在五轴加工中,只能提供机床坐标系下轴指令编程的问题.基于双转台五轴机床运动学转换关系,综合考虑机床动力学约束和加工路径约束,通过在实时插补中完成工件坐标系下编程指令到机床控制点的转换,来实现五轴加工用刀具中心点插补功能.使得数控系统可以在旋转轴插补的同时,自动对控制点进行实时补偿,确保刀具中心点位于编程轨迹,从而使五轴加工程序能够在不同配置结构的机床上运行,简化加工程序编制,增强程序代码的可读性.
In the five-axis machining of NC system, it can only provide the programming of the axis command in the machine coordinate system.Based on the kinematic transformation of the five-axis dual-turret machine tool, considering the dynamic constraints of the machine tool and the processing path constraints, Complete the workpiece coordinate system programming instructions to the machine control point conversion, to achieve five-axis machining tool center point interpolation function.Make CNC system can rotate axis interpolation at the same time, the control point for real-time compensation to ensure that the tool center The point is located in the programming path so that the five-axis machining program can run on different configurations of the machine tool, simplifying the programming of the machining program and enhancing the readability of the program code.
