2. Electromagnetic forming is rarely used to form tubular shapes.

False

True

3. Which of the following is true about push type shapers?

The ram moves away from the machine column while cutting the metal

The workpiece moves away from the column machining

The ram moves away and the workpiece moves towards the machine column

The ram moves towards the machine column while cutting the metal

4. Which of the following is the advantage of shaping process?

Higher tool life

Large objects can be machined easily

Thin or fragile workpiece can also be machined

Lower machining time

5. In how many types roll forming lubricants are categorised?

6. What is the main advantage of broaching over shaping process?

Use of single point cutting tool which are inexpensive and can be grounded to any shape

Thin or fragile jobs can be conveniently machined because of lower cutting forces

Does not require lubrication

Leaves tool marks

Does not require any cleanup

8. It is difficult to form materials with high yield and ultimate tensile strength. Why?

High fatigue strength

Lower elongation

High ductility

Lower creep resistance

Milling

Drilling

Casting
