From the perspective of the mechanical properties influencing surface roughness, the establishment of mechanical model of surface roughness in high-speed machining and the effective prediction of surface roughness will greatly reduce the cost of tests.
In addition, domestic and foreign scholars have taken the cutting speed, feed and back cutting depth and other cutting parameters into the main consideration in the study of the factors affecting surface roughness.
Therefore, the workpiece physical properties can’t be ignored in the surface roughness researches.
Otherwise, the remnant height is one of the main factors affecting surface roughness according to the roughness geometry definition.
It proves that the mechanical model can reveal the effect of the machined material physical properties on the surface roughness, especially the effects of the flow stress in the strong thermo-mechanical coupling of the cutting area.
