Free CMM Preventive & Predictive Maintenance Questions and Answers — Questions and Answers
Question 1: What is the primary goal of preventive maintenance?
- Increase equipment runtime
- Perform maintenance only after failure
- Reduce equipment downtime through scheduled service (Correct answer)
- Eliminate the need for inspections
Correct answer: Reduce equipment downtime through scheduled service
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?
- Screwdriver
- Paint sprayer
- Vibration analyzer (Correct answer)
- Vacuum cleaner
Correct answer: Vibration analyzer
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?
- Lower up-front cost
- Longer wait times before repairs
- Improved equipment reliability (Correct answer)
- Increased repair frequency
Correct answer: Improved equipment reliability
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?
- Replacing an engine after failure
- Ignoring system alerts
- Lubricating bearings regularly (Correct answer)
- Waiting for breakdown
Correct answer: Lubricating bearings regularly
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?
- Employee vacation days
- Weather patterns
- Maintenance tasks and intervals (Correct answer)
- Catering expenses
Correct answer: Maintenance tasks and intervals
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.
Question 6: Why is data collection important in predictive maintenance?
- To plan office parties
- To eliminate routine inspections
- To anticipate failures before they occur (Correct answer)
- To increase emergency repairs
Correct answer: To anticipate failures before they occur
Data collection is fundamental to predictive maintenance, as it provides the raw information needed to assess equipment health. By continuously monitoring parameters like vibration, temperature, or pressure, data allows for the analysis of trends and anomalies, enabling maintenance teams to predict potential failures and schedule interventions proactively.
