Analysis of critical negative rake angle and friction characteristics in orthogonal cutting of AL1060 and T2 [PDF]

open access: yesScience Progress, 2020
The stagnant region often appears in front of the tool cutting edge, which is caused by mechanical inlay and excessive pressing in plastic metal cutting with large negative rake angle tools at a low speed.

Slip-line metal cutting model with negative rake angle [PDF]

open access: yesJournal of the Brazilian Society of Mechanical Sciences and Engineering, 2012
A small dead region is seen in front of the rake face of the tool during cutting with negative rake. The lack of knowledge about the stagnant region in the cutting with negative rake requires researching new models. In this work, cutting mechanism of the metal cutting with negative rake angle tools and the stagnation zone formation were studied.
