Solved Step by Step With Explanation- Turning Parameters and Calculations

Answer

• Cutting ratio (r) = 0.536

• Rake angle (α) = 8 degrees

tan(φ)≈0.5296/0.8608

Now, find φ:

The shear strain (γ) can be determined using the shear plane angle (φ) and the following formula:

γ=cot(φ)+tan(φ−α)

γ=cot(29.84°)+tan(29.84°−8°)

Using the cotangent and tangent values for 29.84° and 29.84° - 8°:

Given:

• Feed (f) = 0.30 mm per revolution

=0.78mm2

Now, convert the cutting speed to mm/s (1 m = 1000 mm):

=0.30mm∗2.6mm∗1800mm/s

=1404mm3/s
