1. A measurement method of undeformed chip thickness in micro-milling, comprising the steps of:
S1: acquiring a surface topography picture of the bottom of a flute after micro-milling;
S2: extracting a tool mark at the central line of the flute from the surface topography picture;
S3: calculating a spacing distance between adjacent tool marks and calculating the difference of equivalent cutting radius between adjacent cutter teeth based on the spacing distance between adjacent tool marks; and
S4: reconstructing the instant undeformed chip thickness in micro-milling based on the difference of equivalent cutting radius between adjacent cutter teeth.
