This video is about the explanation/description/definition/analysis of Merchant' circle cutting force diagram thin plane model used in mechanics of orthogonal metal cutting tool(sharp along the clearance face) geometry machining operations process in manufacturing/production technology of mechanical engineering regarding its assumption(continuous chips(ductile material preferred )without Built up edge(BUE),edge is perpendicular to the direction of motion derivation of various parameters such as friction/shear angle(from minimum energy principle)/velocity or its coefficient,chip thickness ratio(less than 1(from rake angular measurement)or speed ,total work done / power , material removal rate(MRR) ,strain rate or Normal and Frictional component calculation.The plastic deformation occurs during this process.
