You have been asked to work on some design problems and technically support the team working on material removal processes: 1. Technician is turning (lathing) a work material with a shear strength of 270 MPa as shown in Figure 1. The following conditions are used: v = 5.0 m/s, f = 0.30 mm/rev, d = 3.0 mm, and rake angle = 15° in the direction of the chip flow. The resulting chip ratio = 0.5 , material removal rate = 4500 mm3/min ,shear plane angle = 29.02° and the shear strain is = 2.052. Chip Tool R. RF: Turning process.Using the orthogonal model as an approximation of turning, you have been asked to determine: (a) Shear force. (b) Cutting force and thrust force. (c) Friction angle.
