Question 4
During orthogonal machining, shear angle is 35 °. For minimum power consumption, the ratio of cutting force to thrust force will be
Question 5
A bar of 75 mm diameter is reduced to 73 mm by a cutting tool, while cutting Orthogonally. If the mean length of cut chip is 73.9 mm and rake angle is 10°, the shear angle will be _____ degrees.
Question 6
In an orthogonal cutting test on mild steel, the following data were obtained Cutting speed: 40 m/min
Depth of cut: 0.3 mm
Tool rake angle: + 5o
Chip thickness: 1.5 mm
Cutting force: 900 N
Thrust force: 450 N
Using Merchant’s analysis, the Friction angle during the machining will be
