Claim 8:
9. The measurement system of undeformed chip thickness in micro-milling of claim 8, wherein the calculating the difference of equivalent cutting radius between adjacent cutter teeth based on the spacing distance between adjacent tool marks further comprises:
if there is any cutter tooth that is not engaged in cutting, then setting the difference between the equivalent radius of the cutter tooth that is not engaged in cutting and the equivalent radius of any one cutter tooth to negative infinity; and for the cutter tooth engaged in cutting, calculating the difference of equivalent radius between adjacent cutter teeth based on the formula:

ΔRk,k−idk,k−ii·ƒz 

where i is the difference of sequence number between two adjacent cutter teeth engaged in cutting.
