Optimization of hob control for high-speed dry cutting of gears

齿轮高速干切加工是轴承齿轮成形加工的主要环节,针对传统的数控滚齿加工误差较大的问题,提出一种基于主轴振动响应函数模型推导的齿轮高速干切加工滚刀控制模型。采用内齿干涉插值修正方法进行齿轮高速干切加工的模量分解,构建加工滚刀控制的约束参量模型,采用自适应误差反馈修正方法进行加工误差修正,构建齿轮滚刀控制的主轴振动响应函数,根据函数优化向量解的推导模型实现工艺参数优化,实现滚刀优化控制。仿真结果表明,采用该方法进行齿轮高速干切加工的滚刀控制,提高加工精度,优化了加工工艺参数。

The gear high-speed dry cutting is the main part of bearing gear forming process. In view of the traditional NC rolling gear machining error,this paper proposes a new control model of gear high-speed dry cutting processing based on response function model of the spindle vibration. Research the hob tooth interference and interpolation method to achieve machining modulus decomposition of gear high-speed dry cutting construction,construct constrained parameter model of processing hob control,use the adaptive error feedback correction method to process error correction,construct the spindle vibration response function of gear hob control,according to the function optimization model to solution vector,realize the optimization of process parameters,realize the hob optimization control. The simulation results show that the hob control method of gear high-speed dry cutting processing improves processing accuracy,and optimizes processing parameters.
