Oswal Electricals Interview Questions, Process, and Tips

Geometric Dimensioning and Tolerancing (GD&T) is used to define the allowable variations in form, size, and orientation of parts in engineering drawings.

• GD&T ensures clear communication of design intent between designers, engineers, and manufacturers.

• It allows for more precise and efficient manufacturing processes by specifying tolerances for dimensions and geometric features.

• GD&T reduces the need for excessive measure...read more

First angle projection is a method of creating engineering drawings where the object is placed in the first quadrant, while third angle projection places the object in the third quadrant.

• First angle projection is commonly used in Europe and Asia, while third angle projection is more common in North America.

• In first angle projection, the object is placed between the observer and the plane of projection, while in third a...read more

Different types of tolerances include bilateral, unilateral, limit, and fit tolerances.

• Bilateral tolerance: Allows for variation in both directions from the nominal dimension.

• Unilateral tolerance: Allows for variation in only one direction from the nominal dimension.

• Limit tolerance: Specifies the maximum and minimum acceptable dimensions for a part.

• Fit tolerance: Determines the acceptable clearance or interference betw

MSA Study is conducted to assess the measurement system variation and ensure accurate and reliable measurements.

• To identify sources of variation in the measurement system

• To quantify the amount of variation contributed by each source

• To determine if the measurement system is capable of producing accurate and reliable results

• To make improvements in the measurement system if necessary
