An Analysis on the Numerical Prediction of Surface Error in the Face Milling Process of Complex Structural Components
Author(s): 
Pages: 284-288
Year: Issue:  3
Journal: Transactions of Beijing Institute of Technology

Keyword:  端铣加工切削力误差预测加工变形;
Abstract: 针对复杂结构件端铣加工变形问题,用理论与实验相结合的方法进行端铣加工过程仿真及误差预测.用实验方法对修正的端铣切削力理论模型进行验证,将理论计算与有限元方法相结合,采用加工过程离散与载荷等效的方法将瞬态切削载荷动态施加于工件的有限元模型上,应用热-力耦合分析方法,模拟复杂结构件的端铣加工过程,预测工件被加工表面变形误差.实验及仿真结果验证了所提出的仿真预测方法的可行性与有效性.
