齿轮加工 CNC 系统的联动控制结构研究

Research on simultaneous control structure of gearmachining CNC system

从齿轮加工所需要的运动关系出发，推导出齿轮加工ＣＮＣ系统的基本联动控制结构是一种混合的五联动结构．经运动关系独立性分析，得到了一种双基准源结构．在这种双源结构中，五坐标联动是一个两坐标联动结构和一个三坐标联动结构的合成．

The simultaneous control structure is key to design gearmachining CNC system. From the motion relation needed in gearmachining, the basic simultaneous control structure of gearmachining CNC system is deduced in this paper, and the number of simultaneous control motions comes to five. By analyzing the independence of the motion relation in gearmachining, a doublebasicmotions structure is obtained. In this doublebasicmotions structure, the five simultaneous control structure is the composition of a twosimultaneous control structure and a threesimultaneous control structure.
