I applied via Approached by Company and was interviewed in Jul 2022. There were 3 interview rounds.
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

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)...
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...
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

Pipes and tubes are cylindrical structures used for fluid transportation.
Pipes are typically used for conveying liquids and gases, while tubes are used for structural applications.
Pipes are measured by their inner diameter, while tubes are measured by their outer diameter.
Common materials for pipes and tubes include steel, copper, and PVC.
Examples of pipe applications include plumbing, oil and gas transportation, and i...
The type of spindle depends on the machine and its intended use.
Spindles can be classified as belt-driven, motorized, or direct-drive.
Belt-driven spindles are commonly used in milling machines.
Motorized spindles are used in high-speed machining centers.
Direct-drive spindles are used in precision grinding machines.
Spindles can also vary in terms of their speed, torque, and power ratings.
