Optimization of cutting force fitting model by Fast Fourier
Proper milling parameters can prevent tool wear, poor surface quality, and extra costs to the manufacturer. While most milling studies involve tool diameters larger than 1 mm, it has been shown that the typical micro-milling nonlinear force-uncut chip thickness relationship can be observed using a tool diameter as small as 2 mm [1].
