. Figure 5 shows the slip-line field for machining using a cutting tool with restricted contact length 1. Assume that the friction coefficient at the tool rake face is . The shear yield strength of the workpiece material is k. The uncut chip thickness h makes an angle ZCAD = 30. Assume the shear yield strength of the workpiece material is 300 MPa, the tool-workpiece friction coefficient is = 0.3, the tool rake angle is a 10. The length of AB is 1=0.2 mm, and the width of cut of the tool edge in the out-of-plane direction is 3 mm. Calculate the horizontal cutting force.
