According to previous research of dynamic end milling models, the instantaneous dynamic radii on every cutting position affects the cutting forces directly since the simulated forces are proportional to the chip thickness, and the chip thickness is a function of dynamic radii and feedrate. With the concept of flute engagement introduced, it is important to discuss it with respect to radial and axial depths of cut because the length of the engaged flutes is affected by factors in the axial feed and rotational directions. Radial and axial depths of cut affect the ”contact area”, which is the area that a cutter contacts with the workpiece. When radial and axial depths of cut increase, the cutting forces also increase since the engaged flute lengths are increased. Therefore, in order to have a clearer idea of the milling forces, the influences of dynamic radii, cutting feedrate, and radial and axial depths of cut are discussed in this paper.
