Tata Cummins Maintenance Engineer Interview Questions, Process, and Tips

A CNC machine can have 3, 4, or 5 axes depending on its configuration.

• The X, Y, and Z axes are common in 3-axis machines.

• 4-axis machines add a rotary axis, usually the A-axis.

• 5-axis machines add a second rotary axis, usually the B-axis.

• Some machines may have additional axes for specialized operations, such as milling machines with a tilting spindle head.

• The number of axes determines the machine's capabilities and the c

Maintenance procedure involves regular inspection, cleaning, repair and replacement of equipment to ensure optimal performance and prevent breakdowns.

• It is possible that the interviewer made a mistake or was trying to ask a different question.

• As a maintenance engineer, it is important to clarify any unclear or confusing questions to ensure accurate responses.

Types of maintenance include corrective, preventive, predictive, and proactive maintenance.

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

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

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

• Proactive maintenance involves identifying and addressing potentia...read more

The number of points in a PM checklist varies depending on the equipment being checked.

• PM checklists are specific to each piece of equipment.

• The number of points in a PM checklist can range from a few to hundreds.

• Points in a PM checklist can include tasks such as inspecting, cleaning, and lubricating equipment.

• The purpose of a PM checklist is to ensure that equipment is properly maintained and to prevent breakdowns.

Machines need regular preventive maintenance (PM) to ensure optimal performance and longevity.

• Regular cleaning and lubrication

• Inspection and replacement of worn parts

• Calibration and adjustment of sensors and controls

• Testing and monitoring of performance

• Documentation of maintenance activities

• Training of operators and maintenance staff

MTTR stands for Mean Time To Repair and MTBF stands for Mean Time Between Failures.

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

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

• MTTR is used to measure the efficiency of maintenance and repair processes.

• MTBF is used to measure the reliability of a system or equipment.

• MTBF = (total operating time - total downtime)...read more

MTTR is the average time to repair a failed system while MTBF is the average time between failures.

• MTTR measures the maintainability of a system while MTBF measures its reliability.

• MTTR is calculated by dividing the total downtime by the number of failures while MTBF is calculated by dividing the total uptime by the number of failures.

• MTTR is usually shorter than MTBF as it only measures the time to repair a failed sys...read more

Breakdown is an unexpected failure of equipment or machinery. KPI stands for Key Performance Indicator, a measurable value that indicates how well a company is achieving its goals.

• Breakdown can cause production delays and loss of revenue

• KPIs can be used to track maintenance performance and identify areas for improvement

• Examples of KPIs for maintenance include equipment uptime, mean time between failures, and maintenanc
