Tech Mahindra Senior Engineer Interview Questions, Process, and Tips

GD&T stands for Geometric Dimensioning and Tolerancing. It is a system for defining and communicating engineering tolerances.

• GD&T is used to specify the allowable variations in form, size, and orientation of part features.

• It helps improve communication between designers, engineers, and manufacturers by providing a clear and concise way to define part requirements.

• GD&T uses symbols, such as position, concentricity, and ...read more

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

• First angle projection places the object in the first quadrant, with the plane of projection between the observer and the object.

• Third angle projection places the object in the third quadrant, with the plane of projection behind the object.

• First angle projection is commonly used in Europe and Asia,...read more
