Abstract: The burr is one of the common phenomena occurring in metal
cutting operations. The mathematical-mechanical model of two
side-direction burr formation and transformation is established
with plane stress-strain theory, based on the orthogonal
cutting. The main laws of formation and change of the burr are
revealed, and it is confirmed by experiment result, which first
realizes prediction of the forming and changing of the two
side-direction burr in metal cutting operation.
Key words: Metal cutting Two side-direction
burr Mathematical-mechanical model Prediction Precision and ultraprecision machining
