Visual Inspector Interview Questions and Answers

Bearings are mechanical components that reduce friction between moving parts and support axial and radial loads.

• There are several types of bearings, including ball bearings, roller bearings, and plain bearings.

• Ball bearings use balls to reduce friction and support radial and axial loads.

• Roller bearings use cylindrical, tapered, or spherical rollers to reduce friction and support radial and axial loads.

• Plain bearings, also known as bushings, use a sliding motion to reduce fric...read more

Visual inspection may miss subtle defects or abnormalities that are not easily detectable by the human eye.

• Visual inspection may not be able to detect microscopic defects or abnormalities.

• It may not be able to identify defects that are hidden or obscured by other objects or materials.

• Visual inspection may not be able to accurately assess the quality or functionality of complex systems or components.

• It may not be able to detect defects or abnormalities that are only visible un...read more

Visual defects are abnormalities or imperfections in the appearance of an object or image.

• Visual defects can be caused by various factors such as lighting, color contrast, or distortion.

• Examples of visual defects include blurriness, distortion, color fringing, and pixelation.

• Visual defects can affect the quality and clarity of images, making them difficult to interpret or use.

• Visual defects can be corrected through image processing techniques or by adjusting the environment i...read more

An automobile is a motor vehicle designed for transportation on roads.

• It typically has four wheels and an engine.

• It is used for personal transportation, as well as commercial purposes.

• Examples include cars, trucks, buses, and motorcycles.

The differential is a device that allows wheels to rotate at different speeds while driving on a curve or turning.

• It helps to distribute power between the wheels

• It allows for smooth turning and prevents tire wear

• It is essential for four-wheel drive and all-wheel drive vehicles

The gearbox is a mechanical device that transmits power from an engine to the wheels.

• It changes the speed and torque of the vehicle's wheels.

• It allows the engine to operate at an optimal speed range.

• It can be manual or automatic.

• It can have multiple gears for different driving conditions.

• Examples: manual transmission, automatic transmission, continuously variable transmission (CVT).

Tolerance refers to the acceptable range of variation in a measurement or dimension.

• Tolerance is the maximum allowable difference between the actual measurement and the desired measurement.

• It is important in manufacturing to ensure that parts fit together properly.

• For example, if a hole is supposed to be 1 inch in diameter with a tolerance of +/- 0.005 inches, the actual hole diameter can range from 0.995 inches to 1.005 inches.
