摘　　要：介绍了利用CATIA软件对螺旋锥齿轮整个齿轮进行完全自动化切齿的仿真方法,即在CATIA中通过编程输入机床的位置和运动参数,控制齿坯和刀具之间的关系,以便进行切齿仿真,实现了高精度齿面的虚拟加工。介绍了在CAT-IA中导入格里森TCA方法,得到理论齿面离散点后直接在软件中将仿真的齿面与理论齿面比较来验证齿面精度的方法,不仅可以仿真出高精度三维理论齿面与过渡曲面,还将为误差齿面的有限元分析以及研究机床的切齿误差形成原理及补偿方法(切齿调整)提供一个虚拟的三维齿面数据研究平台。Introduces the simulation of using CATIA in the processing of complete automation gear cutting of spiral bevel gears. To input the machine tool＇s position and motion parameters by programming to control the movement between blank and tool of gear in CATIA, which achieve high-precision virtual machining tooth. And it introduces import Gleason TCA theoretical in CATIA to available for discrete points,which directly verify the accuracy of the tooth surface with the software in comparing of emulational tooth surface and theoretical tooth surface method. The method can not only get simulation of high-precision three-dimensional theory tooth surface and blend surface but also offer the virtual three-dimensional tooth surface data research to make finite-element analysis of error tooth surface and tooth cutting error forming reason of tool and the compensation method as tooth cutting regulation.
