WebJan 1, 2024 · Chip reduction coefficient was estimated using the ratio of chip thickness to uncut chip thickness. Uncut chip thickness was numerically estimated through the product of feed and Sin θ. Where ‘θ’ is approach angle and its value is 95°. All the graphs and regression models have been developed using Minitab 17. http://www.minaprem.com/numerical/determine-main-cutting-force-radial-force-normal-force-and-shear-force/
WebApr 25, 2024 · There exists another term called Chip Reduction Coefficient (CRC), which is the ratio between chip thickness and uncut chip thickness. Thus CRC is nothing but inverse of CTR. Orthogonal rake angle of the cutting tool is given as +10° and CTR is 0.4. The shear angle is the angle of inclination of the shear plane from the cutting velocity … http://www.minaprem.com/numerical/shear-angle-using-rake-angle-uncut-chip-thickness-and-nominal-chip-thickness/
