GD&T Interview Questions
FAQ
How do you explain GD&T in an interview?
Sample Answer: “GD&T is a set of symbols and rules used in engineering design to specify the geometric features, dimensions, and tolerances of a part. It allows engineers to communicate design intent precisely, ensuring that the parts meet functional requirements and can be manufactured correctly.
Which skills do engineers working with GD&T need?
You need to understand the underlying concepts and principles of GD&T, such as datums, feature control frames, tolerance zones, material conditions, and bonus tolerances. You also need to know how to apply them in different scenarios and situations, such as when dealing with assemblies, inspection, and measurement.
What is GD&T experience?
GD&T, short for Geometric Dimensioning and Tolerancing, is a system for defining and communicating design intent and engineering tolerances that helps engineers and manufacturers optimally control variations in manufacturing processes.
Which skills would you use to measure perpendicular tolerance?
Perpendicularity is measured using a height gauge, similar to flatness, however, the gauge (or part) is locked to a 90° datum to measure how perpendicular the surface is. The entire surface has to be measured if it is a flat feature.
