In high speed Computer Numerical Control (CNC) machines, cut velocities greater than 60 m per minute and accelerations higher than 2 g are used.
Cutting velocity exerts the least effect on cutting resistance, followed by tooth height and dip angle of cutting edge.
Furthermore, workpiece with different microstructures and dimensions, as well as cutting tool with different geometries, can be constructed easily through modeling; and the machining parameters such as nominal depth of cut and cutting velocity can be adjusted conveniently for each nanometric cutting simulation.
During the tests, performed at low cutting speed, avoiding thermal effects, and high speed, to investigate about the effect of the cutting velocity on the cut quality, the fibre orientation respect to the cutting direction, the tool rake angle and the depth of cut were varied to investigate their influence on the phenomenon.
The cutting parameters considered are cutting velocity, feed rate, depth of cut and step over.
cutting velocity, feed rate, depth of cut, tool nose radius and different concentrations of solid-liquid lubricants, were studied.
The effect of cutting velocity, feed rate, primary depth-of-cut and secondary depth-of-cut has been analyzed on average surface roughness.
Besides, larger cutting velocity and rake angle both will result in larger magnitude of critical depth of cut and MSE.
Very few things would stop a bullet directly, but could cut down their velocity.
