Federal Mogul Goetze Engineer Trainee Interview Questions and Answers

Bearings are mechanical components that allow for smooth rotation or movement between two parts.

• Types of bearings include ball bearings, roller bearings, plain bearings, and fluid bearings.

• Ball bearings use balls to reduce friction between two surfaces.

• Roller bearings use cylindrical rollers to support radial and axial loads.

• Plain bearings have a sliding surface instead of balls or rollers.

• Fluid bearings use a thin lay

Bearings are used to reduce friction between moving parts in machinery, allowing for smooth rotation or linear motion.

• Bearings are commonly used in vehicles, industrial machinery, and household appliances.

• They help support and guide rotating or linear moving parts, reducing friction and wear.

• Examples include ball bearings, roller bearings, and plain bearings.

• Bearings can also be used in applications such as electric mo

Material heat treatment types include annealing, tempering, quenching, and normalizing.

• Annealing: heating the material to a specific temperature and then slowly cooling it to relieve internal stresses and increase ductility.

• Tempering: heating the material to a moderate temperature and then cooling it to improve toughness and reduce brittleness.

• Quenching: rapid cooling of the material to increase hardness by forming mar...read more

Cycle time is the total time taken to complete a process or task from start to finish.

• Cycle time is a key metric in process improvement and efficiency analysis.

• It helps in identifying bottlenecks and areas for improvement in a process.

• For example, in manufacturing, cycle time can refer to the time taken to produce one unit of a product.

• Reducing cycle time can lead to increased productivity and cost savings.

Line balancing is the process of assigning tasks to workstations in a way that evens out the workload and maximizes efficiency.

• Involves distributing work evenly among workstations

• Helps in reducing idle time and bottlenecks

• Improves productivity and efficiency

• Example: In a manufacturing plant, line balancing ensures each workstation has a similar amount of work to do

A random cylinder is a geometric shape defined by a random height and radius, often used in probability and statistics.

• A random cylinder can be defined by its height (h) and radius (r), which can vary randomly.

• In probability, random cylinders can model real-world phenomena, like the distribution of particles in a volume.

• Example: If the height of a cylinder is uniformly distributed between 1 and 10 units, and the radius...read more

OEE stands for Overall Equipment Effectiveness, a metric used to measure manufacturing productivity.

• OEE is calculated using three components: Availability, Performance, and Quality.

• Availability = (Operating Time / Planned Production Time) x 100%. Example: If a machine runs for 8 hours but is down for 1 hour, availability is 87.5%.

• Performance = (Actual Output / Maximum Possible Output) x 100%. Example: If a machine prod...read more
