考虑工件变形的钛合金侧铣力预测方法
Prediction Method of Side Milling Force of Titanium Alloy Considering Workpiece Deformation
摘要
Abstract
To improve the prediction accuracy of milling force by considering the time-varying contact relationship between the workpiece and the tool,a milling force prediction method considering strain softening of materials and workpiece deformation is proposed,which reveal the essential properties of materials under high strain rates.Firstly,a micro-element cutting force model was constructed based on the TANH material constitutive model and the oblique cutting theory.Considering the workpiece deformation due to cutting depth,Euler-Bernoulli beam theory was introduced to calculate the elastic deformation of workpiece,and more accurate cutting force was obtained.Secondly,orthogonal milling test was designed and the tested data with the simulated was compared.The results show that the maximum average error is 12.71%in X direction and 11.28%in Y direction.The method effectiveness is verified.关键词
