高速铣削中刀具偏心跳动参数辨识

摘要

针对高速铣削中刀具偏心跳动对切削厚度、加工精度以及刀具寿命等的影响问题，通过力学建模建立瞬时切削模型与偏心跳动模型、分解出由偏心跳动引起的铣削力，确定偏心跳动参数辨识过程，以平头立铣刀为例通过试验论证该方法的正确性，为高速铣削中铣削力参数的精确确立奠定基础。%Aimed at the problems with tool runout effect on cutting thickness , machining accuracy and tool life . etc. establish the instantaneous cutting model and the runout model based on means of mechanics mod-eling , The runout milling force was decomposed , The Runout Parameters identification process is deter-mined, The correctness of the method is demonstrated by the experiment In the case of the flat end milling cutter, all these made good foundation on the accurate establishment for the milling force parameters in high speed milling .
