Study on Flute Design for End Mill Based on Oblique Cutting Model
Aimed at the design of the radius of flute for solid carbide end mill, a new oblique cutting model for milling was established based on the simplified model of milling layer. Depending on this model, an equation was developed to calculate the maximum chip thickness in milling. An oblique cutting simulation via FEM(Finite Element Method) was conducted to verify the equation. The conclusion was that the result gained from the simulation was in a good agreement with the present model, so the present model is reasonable to predict the maximum chip thickness in milling and to determine the radius of the arc at the bottom of the flute.
