1. What is the difference between forming and machining? 2. List 3 basic machining processes. Show a sketch for each with tool and work piece movement direction. 3. Give the force components for oblique and orthogonal machining. 4. What is different about the workpiece and tool for turning vs boring? 5. The equations for cutting speed, machining time, and metal removal rate are the same for turning and boring? TRUE or FALSE 6. For a lathe,...
1. A certain work material has shear strength of = 50,000 lb/in. An orthogonal cutting operation is performed using a tool with a rake angle = 20° at the following cutting conditions: cutting speed - 100 ft/min, chip thickness before the cut = 0.015 in, and width of cut = 0.150 in. The resulting chip thickness ratio = 0.50. Determine (a) The shear plane angle; (b) Shear force; (c) Cutting force and thrust force, and (d) Friction force. 2.1 The...
