Solution:
Where is the maximum shear stress theory used?
Solution:
The angle by which the face of a cutting tool is inclined sideways is known as which of the following?
Solution:
Why should blind corners and radii be avoided while roll forming?
Solution:
During orthogonal cutting of mild steel with a 10° rake angle tool, the chip thickness ratio was obtained as 0.4. The shear angle (in degrees) evaluated from this data is
Solution:
A 110 mm diameter hole needs to be punched in a 6 mm thick sheet of cold rolled steel with a shear strength of 560 MPa. Find the diameter of the die required.
Solution:
In an orthogonal cutting operation, the depth of cut is 0.40 mm and the uncut chip thickness is 0.80 mm. If the cutting speed is 4 m/s, calculate the chip velocity.
Solution:
Find the bending force required to bend a 2 mm thick C50 steel plate that is 1 m long over a wiping die. The radius used is 3 mm, and the ultimate tensile stress for C50 steel is 800 MPa.
Solution:
Cutting power consumption in turning can be significantly reduced by
