Classification: CPC G  Y | IPC G

Claim 6:
7. A measurement system of undeformed chip thickness in micro-milling, comprising:
an acquisition module configured to acquire a surface topography picture of the bottom of a flute after micro-milling;
a tool mark extraction module configured to extract a tool mark at the central line of the flute from the surface topography picture;
a spacing distance calculation module for adjacent tool marks configured to calculate a spacing distance between adjacent tool marks; and
a calculation module of equivalent cutting radius difference configured to calculate the difference of equivalent cutting radius between adjacent cutter teeth based on the spacing distance between adjacent tool marks; and
an undeformed chip thickness calculation module configured to reconstruct the instant undeformed chip thickness in micro-milling based on the difference of equivalent cutting radius between adjacent cutter teeth.
