Chip thickness ratio formula

WebIn an orthogonal machining with a single point cutting tool of rake angle 10 o, the uncut chip thickness and the chip thickness are 0.125 m m and 0.22 m m respectivley. Using Merchant's first solution for the condition of minimum cutting force, the coefficient of friction at the chip-tool interface is (round off to two decimal places). WebJun 15, 2001 · A new model for determining the undeformed chip thickness. The true undeformed chip thickness in Eq. (15) can be equivalently rewritten as: h tr = MN = MC − NC =r− (x N −x C) 2 + (y N −y C) 2 Eq. (14) is a transcendental equation and a numerical method has to be used to solve it. To avoid this cumbersome numerical …
