Experiments in the Machining of Ice at Negative Rake Angles
Journal of Glaciology, 1984 AbstractThe cutting force components and the cutting moment on the cutting tool were measured during the orthogonal machining of ice with cutting tools inclined at negative rake angles. The variables included the cutting depth (< 1 mm), the cutting speed (0.01 ms−1 to 1 ms−1), and the rake angles (–15° to –60°).

MINIMIZING TEMPERATURE AND TOOL WEAR ON ROCK CUTTING WITH NEGATIVE RAKE ANGLE
MM Science Journal, 2019 This research discusses the effect of negative rake angle, to the temperature and tool wear on rock cutting. The cutting process was conducted on marble rock material, without coolants and utilized tungsten carbide inserts with 0o , -5 o , -10o , -15o , -25o , - 30o and -40o rake angles; meanwhile, the feed rate, spindle speed and depth of cut were ...

Friction in Orthogonal Cutting Finite Elements Models with Large Negative Rake Angle [PDF]
Tribology in Industry, 2016 In this paper, orthogonal cutting finite elements models are built for the investigation of the impact of large negative rake angles on the friction coefficient in the tool-chip interface in machining. The simulation results give an insight on the mechanism of chip formation in processes with large negative active rake angle, such as machining with ...
