Summary Experimental orthogonal machining results are given which show that the ratio of the force normal to the cutting direction to the force in this direction increases with decrease in undeformed chip thickness as well as with increase in negative rake angle.

Soil translocation by narrow openers with various rake angles
Biosystems Engineering, 2012Australian no-till farming often uses narrow point openers to open the soil and place seed and fertiliser in the furrow, in conjunction with spraying pre-emergence herbicides and using press-wheels to pack soil over seeds. At speeds above 6 km h −1 these openers can create excessive soil throw which creates problems for adjacent furrows, such as ...

Adiabatic shear in chip formation with negative rake angle
International Journal of Mechanical Sciences, 2005The mechanics of chip formation in grinding is investigated based on thermo-elastic-plastic finite element simulations of orthogonal cutting with a large negative rake abrasive-grits. The modeling is coupled with temperature and strain-rate-dependent flow stress characteristics of a work material SK-5 (0.93%C carbon steel). The shape of chip calculated

The Influence of Extreme Speeds and Rake Angles in Metal Cutting
Journal of Engineering for Industry, 1963A study is presented of the effect of wide variations in speed of cutting and rake angle on orthogonal cutting of several metals—mainly a lead-antimony alloy. It was observed that enormous decreases in tool forces occurred in the lead-antimony with increase in speed from 6 to 3800 fpm, and decrease in rake angle from +30° to −60°.

Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering, 2016
In this study, milling operations were carried out using AISI 1040 specimens steel in dry cutting conditions. The cutting tools used in the experiment include P20 tool steel and they also have three different approach angles (45°, 60°, 75°) and rake angles (0°, −6°, −12°).

On the Size-Effect in Micro-Cutting at Low and High Rake Angles
Manufacturing Engineering and Materials Handling Engineering, 2004A partial explanation of the size-effect in the specific cutting energy in micro-cutting is provided in this paper. For a simple orthogonal cutting condition, with constant width of cut, the specific cutting energy is viewed as a ratio of the cutting force and the uncut chip thickness.

The effects of chamfer and back rake angle on PDC cutters friction
Journal of Natural Gas Science and Engineering, 2016Abstract Single PDC cutter tests at a high pressure cell were conducted and analyzed to gain an understanding of the effect of cutter geometry on its frictional response. First, sets of tests conducted with sharp non-chamfered cutters are analyzed. A decreasing trend between the friction angle and back rake angle is consistently observed.
