Worked Solution & Example Answer:8.1 Name THREE effects of a lack of routine maintenance - NSC Mechanical Technology Welding and Metalwork - Question 8 - 2016 - Paper 1
Step 1
Name THREE effects of a lack of routine maintenance.
Answer
-
Risk of injury or even death: Lack of maintenance can lead to equipment failure, posing safety hazards to operators.
-
Financial loss due to damages: Unmaintained equipment is more prone to breakdowns, resulting in costly repairs and losses.
-
Decrease the lifespan of equipment: Routine maintenance helps prolong the life of machinery, and neglecting it can lead to premature wear and tear.
Step 2
Name TWO subgroups of preventative maintenance.
Answer
-
Planned/scheduled maintenance: This involves routine checks and service based on a predetermined schedule to prevent breakdowns.
-
Condition-based maintenance: This method involves monitoring the equipment's condition and performing maintenance only when necessary.
Step 3
Define the following properties of oils:
Answer
8.3.1 Pour point: The lowest temperature at which a liquid remains pourable, indicating its flow characteristics in cold conditions.
8.3.2 Flashpoint: The lowest temperature at which the oil gives off vapor that can ignite, crucial for safety and handling.

Step 5
Why is cutting fluid used on the cutting tool during the machining processes on a centre lathe?
Answer
Cutting fluid is used to keep the cutting tool cool, prolonging its life by reducing overheating. It also helps to wash away swarf or shavings, ensuring a cleaner operation and better finish, ultimately increasing productivity.
