针对数控强力切削中颤振问题，建立了包含切削过程颤振环节的数控强力切削伺服系统数学模型。
Faced with chatter during CNC heavy cutting, we constructed the mathematical model of CNC heavy cutting servo system which contains chatter in the process of cutting.
在数控强力切削进给伺服系统中，机械传动系统对电气调速系统具有扭矩反馈作用，容易形成机械谐振。
In CNC heavy cutting servo system, mechanical drive system has a torture feedback on electrical speed-adjustment system, thus it's possible to generate the mechanical resonance.
通过对五阶系统的分析表明数控强力切削伺服进给系统的谐振频率取决于机械谐振频率和速度环谐振频率中较低的一个。
This system indicates that the resonance frequency of servo drive in CNC heavy cutting is equal to the lower one of mechanism and speed loop resonance frequency.
