TOOLINGU: INTRODUCTION TO GD&T
301 ACCURATE 100%
Which of the following is a two-dimensional tolerance that requires the actual profile of
the feature to fall within two line elements that follow the true profile of the feature? -
ANSWER Profile of a Line
What is cylindricity? Cylindricity is: - ANSWER A three-dimensional tolerance that
independently controls how much a feature can deviate within a tolerance zone formed
by two concentric cylinders.
What is GD&T? GD&T is: - ANSWER A standard that uses universal symbols for
communicating instructions about the design and manufacturing of parts.
Which method of part design uses a square grid of imaginary lines that describes every
feature independently? - ANSWER Coordinate tolerancing
What does Ø symbolize? - ANSWER Diameter
What is the two-dimensional tolerance that independently controls how much a feature
can deviate within a tolerance zone formed by two parallel lines? - ANSWER
Straightness
Which of the following is an orientation tolerance? - ANSWER Perpendicularity
What type of dimensions are enclosed in a rectangular box on a print? - ANSWER
Basic dimensions
Which statement about runout is true? - ANSWER Parts that meet total runout tolerance
by default also meet the corresponding circular runout.
What is one reason why GD&T is an improvement compared to traditional methods for
describing part design? GD&T: - ANSWER Emphasizes the fit and function of the part.
What is a datum? A datum is: - ANSWER A geometrically perfect form.
In which order does the information appear inside of a feature control frame? -
ANSWER 1. A geometric tolerance symbol 2. The total tolerance for the feature 3. Any
datum information
What are the three material condition modifiers that describe a feature in relation to its
size limits? - ANSWER Maximum Material Condition, Least Material Condition, and
Regardless of Feature Size
