Jet machining

Slitting

Solution:

Which of the following statements about Electromagnetic Forming (EMF) is not true?

Leaves tool marks

Does not require lubrication

Does not require any cleanup

It is primarily applied in the forming of good conducting materials

Solution:

If the cutting ratio (r) and rake angle (∝) are given, which of the following equations should be used to calculate the shear angle (ϕ)?

ϕ = π/4 - β/2 + ∝/2

ϕ = tan^-1 (rcos∝/1+rsin∝)

ϕ = tan^-1 (rsin∝/1-rcos∝)

ϕ = tan^-1 (rcos∝/1-rsin∝)

Solution:

Solution:

What is camber in roll forming?

Deviation of the strip edge from a straight line in horizontal plane

Deviation of the strip edge from a straight line in vertical plane

Difference in theoretical and actual elongation of the strip

Waviness of the strip

Solution:
