Free CMM Preventive & Predictive Maintenance Questions and Answers

Question 1

What is the primary goal of preventive maintenance?

Accepted Answer

Reduce equipment downtime through scheduled service

Answer

The primary goal of preventive maintenance is to proactively maintain equipment to avoid unexpected breakdowns. By conducting scheduled inspections, servicing, and minor repairs, it aims to reduce costly downtime, extend asset life, and ensure continuous operation, rather than waiting for failure.

Question 2

Which tool is commonly used in predictive maintenance?

Accepted Answer

Vibration analyzer

Answer

Predictive maintenance utilizes specialized tools and techniques to monitor equipment condition and predict potential failures. A vibration analyzer is a common tool used to detect abnormal vibrations in rotating machinery, indicating wear or misalignment that could lead to future breakdown.

Question 3

What is a benefit of predictive maintenance over reactive maintenance?

Accepted Answer

Improved equipment reliability

Answer

Predictive maintenance continuously monitors equipment health, allowing for repairs to be scheduled precisely when needed, before a failure occurs. This proactive approach significantly improves equipment reliability by preventing unexpected breakdowns, reducing downtime, and optimizing maintenance efforts compared to reactive methods.

Question 4

Which is an example of a preventive maintenance task?

Accepted Answer

Lubricating bearings regularly

Answer

Lubricating bearings regularly is a classic example of a preventive maintenance task. It involves scheduled application of lubricant to reduce friction and wear, preventing premature failure of mechanical components and extending the lifespan of machinery, rather than waiting for a breakdown.

Question 5

What is typically tracked in a preventive maintenance schedule?

Accepted Answer

Maintenance tasks and intervals

Answer

A preventive maintenance schedule systematically outlines all planned maintenance activities. It specifies which tasks need to be performed on particular equipment, how often (the intervals), and often who is responsible, ensuring that critical upkeep is consistently carried out.
