TPM & Predictive Maintenance Flashcards

Which TPM pillar focuses on eliminating the six big losses in equipment effectiveness?

Answer: Focused Improvement (Kobetsu Kaizen)

Focused Improvement targets the six big losses through small-group activities to maximize equipment effectiveness.

In vibration analysis, what does a high amplitude at the fundamental frequency (1X) typically indicate?

Answer: Imbalance

A dominant 1X frequency peak is the classic signature of mass imbalance in rotating equipment.

What is the primary purpose of a P-F interval in predictive maintenance?

Answer: Define the window between detectable failure onset and functional failure

The P-F interval defines how much time is available between when a potential failure is detected and when functional failure occurs.

Autonomous maintenance in TPM primarily shifts which responsibility to operators?

Answer: Basic equipment care such as cleaning, lubrication, and inspection

Autonomous maintenance empowers operators to perform routine care tasks, freeing maintenance technicians for more complex work.

Which oil analysis result most directly indicates active wear of metallic components?

Answer: Rising ferrous particle count

Increasing ferrous particle count in oil samples indicates that metal surfaces are wearing and releasing particles into the lubricant.

The Overall Equipment Effectiveness (OEE) metric of 85% is generally considered world-class for which environment?

Answer: Discrete mass production

An 85% OEE benchmark for world-class performance was established in the context of discrete mass production manufacturing.

In thermographic inspections, which condition is most commonly identified on electrical panels?

Answer: Hot spots caused by loose connections or overloaded circuits

Infrared thermography excels at finding hot spots in electrical panels caused by loose connections, unbalanced loads, or failing components.
