基于三轴联动CNC锥齿轮机床的展成齿面数学模型

The model of the generated tooth surface based on the three-axis CNC bevel gear machine

在Free-form机床中没有摇台,不能以摇台角作为齿面展成参数;齿面的形状理论上取决于机床各轴的联动关系,与时间没有必然的联系,以时间作为齿面展成参数也不合适。因此,以基于Free-form机床的切齿加工理论为基础,直接以工件齿轮的转角作为齿面展成的参数,建立Free-form机床的展成齿面数学模型。

There is no cradle in the Free-form machine,it is impossible to use the cradle angle as the generated parameter.Theoretically,the shape of the gear surface depends on the relations between the axis,no correlation to the time,so it＇s not suitable to use the time as the parameter.At last,based on the theory,the angle of the gear was taken as the generated parameter,the module of the generated tooth sur-face was built.
