Duration: 25 Minutes (10 Points) 1. In a turning operation, cutting speed = 1.8 m/s. Feed = 0.30 mm/rev and depth of cut = 2.6 mm. Rake angle = 8°. After the cut, the deformed chip thickness = 0.56 mm. Determine (a) shear plane angle, (b) shear strain, and (c) material removal rate. Use the orthogonal cutting model as an approximation of the turning process.

Step 1
The shear plane angle (φ) can be calculated using the formula: φ = arctan(tan(α) / cos(β)) where α is the rake angle and β is the clearance angle. Since we are given the orthogonal cutting, the rake angle (α) is 0 degrees and the clearance angle (β) is 90 Show more…

In a turning operation, the spindle speed is set to provide a cutting speed of 1.7 m/s. The feed and depth of cut are 0.30 mm and 2.6 mm, respectively. The tool rake angle is 9°. After the cut, the deformed chip thickness is measured to be 0.38 mm. Determine (a) shear plane angle, (b) shear strain. Use the orthogonal cutting model as an approximation of the turning process.
