where hk (θ) is the instantaneous undeformed chip thickness of the k-th cutter tooth at the reference tooth position angle θ, ΔRk,m is the difference of equivalent radius between any two cutter teeth, θk is a rotation angle of the k-th cutter tooth at the reference tooth position angle θ, M is the number of cutter teeth, and Δθm,k is the angle by which the m-th cutter tooth is ahead of the k-th cutter tooth in the rotation direction of the tool.
