Influence of the radial depth of cut over the harmonic content of the Fourier spectrum in a milling of Aluminum 7075T6

Modelled cutting forces in an Aluminum 7075 T6 milling operation with a Kendu Kenal 4200.61 end mill of 16 mm of diameter, 2 cutting edges and helix angle of 30º. The calculations have been made with three radial depths of cut from 4 to 0,5 mm. The axial depth of cut is fixed at 8 mm, down-milling is used, with a feed per tooth of 0,2 mm and a spindle speed of 2400 rpm.
