Forming Processes

A blacksmith uses what engineering technique?

• Casting

• Forging

• Stereolithography

• Water jet cutting

Forming Processes

Put these steps into the correct order for forging.

• 
• 
• 
• 

Answer explanation

1 - Heat the ingot

2 - Use compressive force to shape the ingot.

3 - Allow the profile to cool.

4 - Carry out secondary finishing such as machining.

Forming Processes

Forging creates products with a higher quality internal grain structure?

• True

• False

Answer explanation

With wasting techniques the grain flow can be broken by the machining and shaping exercises.

Forging provides a grain structure that follows the profile of the object meaning strengths and durability can be greatly improved.

Forming Processes

Forging can be done in 3 typical ways. Match the picture to the technique.

• Open Die

• 
• Upsetting

• 
• Closed Die

• 

Forming Processes

Select the disadvantages of forging.

• Intense safety procedures need to be followed.

• Secondary operations are almost always required.

• The surface of forged metal is prone to rapid oxidisation.

• Forging gives a linear grain profile.

Forming Processes

What does the animation show?

• Vacuum Forming

• Laser Sintering

• Press Forming

• Forging

Forming Processes

Press forming is using a ​ (a)   force to ​ (b)   deform a material to match the size and shape of the ​ (c)  

• pressing
• plastically
• die.
• tensile
• elastically
• tap

Forming Processes

This is the most common type of machine used when press forming. What is it called?

• Punch

• Pyramid Roll

• Press Brake

• Knibbler

Forming Processes

Press brakes can be difficult to fully safe guard. What does the light beam guard actually do on this example?

• Make the danger area glow so you can see properly.

• Provide a red warning light.

• Cut the machines power if you step in the path of the light beams whilst it is running.

• Flash when the machine is in use and sound a warning claxon.

Forming Processes

Press forming uses dies. What product form would you expect to be made from this die arrangement?

•
