Identify the main processes used to manufacture any two of the items shown: (i) machine screw (ii) cylinder head (iii) key
Worked Solution & Example Answer:Identify the main processes used to manufacture any two of the items shown: (i) machine screw (ii) cylinder head (iii) key - Leaving Cert Engineering - Question a - 2009
Step 1
Identify the main processes for (i) machine screw
Answer
To manufacture a machine screw, the main processes used are:
-
Thread Rolling: This is a process where the thread is formed by rolling the screw blank between two dies, which shape the thread into the screw. This process is efficient and provides a strong, accurate thread.
-
Cutting: After the thread has been formed, cutting processes may be employed to achieve the desired length and head shape of the screw.
Step 2
Identify the main processes for (ii) cylinder head
Answer
To manufacture a cylinder head, the main processes used are:
-
Casting: This process involves pouring molten metal into a mold to create the shape of the cylinder head. It allows for complex geometries and is widely used in producing engine parts.
-
Machining: After casting, machining processes such as milling may be employed to refine the surfaces and ensure correct dimensions.
