Chip velocity formula

Webwhere C is the active grain density per unit area, r is ratio of chip width to thickness at any point along the contact length (generally between 5 and 15), v w is the workpiece speed, v c is the cutting speed, i.e., grinding tool circumferential speed, d eq is the equivalent grinding tool diameter and a e is the depth of cut. Both C and r parameters depend on the … WebIt can be determined from the formula: (b = chip width and t = chip thickness before removal from workpiece). Work done in shear (W) (portion of the work done in removing a chip consumed in shearing of the metal on the plane of the shear) can be calculated from the formula W S = S S [cos f + tan (f – α)]

Web"F" (frictional force ) and "Fn" (Force normal to the Shear force; the resistance offered by the work-piece) can be used to define the coefficient of friction between the cutting tool and the chip. The friction force and its normal force can be added vectorially to form a resultant force, R. R is oriented at an angle, called the friction angle. WebFor turbulent flow regimes (Re > 2,000), slip velocity is estimated using (3.50) where u sl = Slip velocity, ft/sec d s = Cuttings diameter, ft ρ s = Cuttings density, lb/ft 3 ρ m = Density of gaseated fluid, lb/ft 3 Slip velocity depends on cuttings size, density of fluid, and density difference between fluid and cuttings.
