Study on Distributing Principle of Force Density Function for Complex Three-Dimension Groove Milling Insert

Based on the milling force testing experiments on machining the carbon structural 45 steel, the study on the distributing principle of force density function for complex three-dimension groove milling insert with the waved-edge milling insert (the curve rake plane) developed by Harbin University of Science and Technology is studied On the basis of the milling force mathematical model, the force density function of the curve rake plane is built by the milling force experiments and tool-chip contact area experiments. Having quantitative calculation on the force density function and programming, the distributing model of force density function is shown with 3D figure, so to analyze its distributing principle. All these studies will provide a theoretic base for the stress field analysis and solving the cutter disrepair which is the key problem in the automatization production and groove optimization
