Manufacturing and Production Machine Operation and Maintenance 3

Question 1

What is 'condition-based maintenance' triggered by?

Accepted Answer

Actual measured equipment parameters exceeding defined thresholds

Answer

Condition-based maintenance triggers action when a measured parameter—such as vibration amplitude or oil particle count—exceeds a defined threshold, indicating developing wear.

Question 2

What is the primary function of a coolant system in a metal machining operation?

Accepted Answer

To cool the cutting tool and workpiece while flushing away chips

Answer

Coolant reduces heat generated at the cutting zone, extends tool life, improves surface finish, and flushes chips away from the workpiece.

Question 3

What does 'calibration' of a measuring instrument or machine mean?

Accepted Answer

Comparing and adjusting the machine's measurements to a known traceable standard

Answer

Calibration compares a machine's or instrument's output to a known traceable standard and adjusts it to ensure measurement accuracy.

Question 4

What is 'root cause analysis' (RCA) used for in machine maintenance?

Accepted Answer

Identifying the fundamental reason a failure occurred to prevent recurrence

Answer

RCA is a systematic process to identify the fundamental cause of a failure—not just the symptom—so corrective actions can be taken to prevent it from happening again.

Question 5

Which document provides step-by-step instructions that maintenance technicians must follow when performing a specific repair task?

Accepted Answer

Standard Operating Procedure (SOP)

Answer

A Standard Operating Procedure (SOP) provides detailed, step-by-step instructions for performing maintenance or repair tasks consistently and safely.
