GD&T questions well answered rated
A+
Angle Plate - correct answer ✔✔ A precise measurement device used to establish an accurate
90° vertical surface
Angularity - correct answer ✔✔ A three-dimensional geometric tolerance that controls how
much a surface, axis, or plane can deviate from the angle described in the design specifications
ASME - correct answer ✔✔ The American Society of Mechanical Engineers. ASME is an
organization that publishes technical materials and sets industrial and manufacturing standards
Bonus Tolerance - correct answer ✔✔ Additional tolerance that applies to a feature as its size
shifts from a stated material condition. Both MMC and LMC allow bonus tolerance.
Circular Runout - correct answer ✔✔ A two-dimensional geometric tolerance that controls the
form, orientation, and location of multiple cross sections of a cylindrical part as it rotates.
Circularity - correct answer ✔✔ A two-dimensional geometric tolerance that controls how
much a feature can deviate from a perfect circle.
Concentric - correct answer ✔✔ Sharing the same center.
Concentricity - correct answer ✔✔ A three-dimensional geometric tolerance that controls how
much the median points of multiple diameters may deviate from the specified datum axis.
, Coordinate Tolerancing - correct answer ✔✔ A system for describing the design of a part that
compares its features to distances along three linear axes. These axes create an imaginary
rectangular grid.
Cross Section - correct answer ✔✔ A section of a feature that is formed by an intersecting
imaginary plane.
Cylindricity - correct answer ✔✔ A three-dimensional geometric tolerance that controls how
much a feature can deviate from a perfect cylinder.
Datum - correct answer ✔✔ An imaginary, perfect geometric shape or form. A perfect point,
line, flat plane, circle, or cylinder are all examples of possible datums.
Datum Feature - correct answer ✔✔ A physical feature that acts as an acceptable substitute for
a datum. Datum features relate the various features of the part to each other.
Datum Reference Frame - correct answer ✔✔ Three imaginary planes perpendicular to one
another that are mapped onto the part to relate features to each other.
Feature - correct answer ✔✔ A physical feature of a part that naturally contains variation and
imperfections. A corner, edge, flat surface, or hole are all examples of possible features.
Feature Control Frame - correct answer ✔✔ A series of compartments containing symbols and
values that describe the tolerance of a feature. The order and purpose of these compartments
follow a consistent standard.
Fixture - correct answer ✔✔ A dedicated workholding device used to locate and hold a part
during machining or inspection.
