Total questions: 12
Worksheet time: 60secs
What is forging?
A casting process using molten metal
A process that shapes metal using compressive forces
A machining process using cutting tools
A heat treatment process
Which force is mainly used in forging?
Tensile
Compressive
Shear
Torsional
What are the three main types of forging based on temperature?
A. Hot, Warm, and Cold
B. Soft, Medium, and Hard
C. Open, Closed, and Die
D. Press, Roll, and Hammer
What distinguishes closed-die forging from open-die forging?
It uses liquid metal
It presses metal between shaped dies
It is performed without heating
It requires no operator control
What is 'flash' in the forging process?
The heat treatment stage
Excess metal squeezed out of the die
A defect in the metal
A cooling lubricant
When should flash removal typically be completed?
When the part is still warm
After the part has cooled
Before forging
During die lubrication
How does forging improve material properties?
By randomizing grain structure
By aligning the grain flow
By melting and re-solidifying
By adding alloying elements
Which of the following is an advantage of forging?
High waste material
Improved mechanical strength
Complex shapes easily produced
Low production speed
Why is forging suitable for high-stress components?
It increases fatigue resistance
It reduces density
It makes parts more brittle
It decreases strength
Which material is commonly used for forging?
Plastic
Carbon Steel
Wood
Ceramic
How does part complexity affect process selection?
More complex parts are forged
Simpler parts are cast
Forging is better for simple, strong shapes
Casting cannot form complex shapes
Why might trimming, grinding, and shot-blasting be combined?
To improve part precision and surface finish
To cool the metal quickly
To increase flash formation
To make casting easier
