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

Influence of the Rake Angle on Nanocutting of Fe Single Crystals: A Molecular-Dynamics Study [PDF]
Crystals, 2020 Using molecular dynamics simulation, we study the cutting of an Fe single crystal using tools with various rake angles α . We focus on the (110)[001] cut system, since here, the crystal plasticity is governed by a simple mechanism for not too ...

About the best value of rake angle for cutting tools [PDF]
MATEC Web of Conferences, 2017 Regardless of whether the case of processing through methods of cutting metal, wood, plastics, stone, composite materials etc., the rake angle (γ) is of major importance for energy efficiency and dynamic behaviour of cutting process, dimensional accuracy, work surface quality and pieces made cost.

Forces and loosening characteristics of a new winged chisel plough
Research in Agricultural Engineering, 2021 This study was devoted to verifying the performance of various configurations of a winged chisel plough (WCP) in a soil bin. The performance of the new tool was assessed at three wing depths (5, 10 and 15 cm), three bend angles (10, 20 and 30 °), and ...
