Construction of Cutting Force Model and Correlation Analysis with Cutting Parameters
In order to optimize milling process parameters and analyze the relationship between milling pa-rameters,milling force and milling force coefficient during milling under the same working condition,based on the existing milling force model and combined with specific milling conditions,this paper designed an experiment to explore the relationship between milling force coefficient and milling speed,that is,by desig-ning the same working condition and different feed rate.The three-way milling force during milling of dif-ferent steps was measured,the shear force coefficient and cutting edge force coefficient during milling of different steps were identified,and the correlation between milling force and milling speed,feed rate and milling depth was explored according to Pearson correlation coefficient.The experimental results show that feed rate and axial depth of cut are highly related to milling force,and the milling force can be directly con-trolled by changing these two milling parameters,which provides a theoretical model for the subsequent re-search of milling.At the same time,tangential cutting edge force coefficient is highly correlated with milling speed,radial and axial cutting edge force coefficient is significantly correlated with milling speed,tangential and radial shear force coefficient is poorly correlated with milling speed,and axial shear force coefficient is significantly correlated with milling speed.It provides theoretical basis and practical research basis for further research on a series of problems such as parameter optimization and physical simulation of milling process.
