FMI Automotive Components Mechanical Maintenance Engineer Interview Questions and Answers

Caliper and gauge are precision measuring tools used in mechanical maintenance.

• Caliper is used to measure the distance between two opposite sides of an object, while gauge is used to measure the thickness or diameter of an object.

• Caliper can be either digital or manual, and is commonly used to measure the dimensions of machine parts.

• Gauge can be a dial gauge, thickness gauge, or bore gauge, and is used to ensure that m...read more

SMPS is a power supply that uses high-frequency switching to convert AC voltage to DC voltage.

• SMPS is more efficient than traditional linear power supplies

• It uses a switching regulator to control the output voltage

• SMPS can be found in computers, TVs, and other electronic devices

• It can be designed to work with different input voltages and frequencies

HMI is the interface between a human operator and a machine that allows for control and monitoring of the machine's functions.

• HMI is used in various industries such as manufacturing, transportation, and energy

• It includes components such as touchscreens, buttons, and indicators

• HMI can display real-time data and provide alerts for potential issues

• Examples of HMI include the dashboard in a car and the control panel in a f

MTBF is Mean Time Between Failures and MTTR is Mean Time To Repair.

• MTBF is the average time between two consecutive failures of a system or component.

• MTTR is the average time taken to repair a failed system or component.

• MTBF and MTTR are important metrics in maintenance engineering to measure system reliability and availability.

• MTBF can be calculated by dividing the total operating time by the number of failures.

• MTTR c...read more

There are generally 4 types of maintenance: corrective, preventive, predictive, and condition-based.

• Corrective maintenance involves fixing a problem after it has occurred.

• Preventive maintenance involves scheduled maintenance to prevent problems from occurring.

• Predictive maintenance involves using data and analytics to predict when maintenance is needed.

• Condition-based maintenance involves monitoring equipment and perfo...read more
