simultaneous requirement

Position and profile controls referencing the same datums in the same order with the same material modifiers are considered a

composite positional requirement

is when multiple patterns of features located relative to common datums are treated as one pattern

Virtual condition

is a constant boundary that considers MMC size + geometric tolerance and is used to size gage elements.is a constant boundary that considers MMC size + geometric tolerance and is used to size gage elements.

Basic dimensions

are used to establish true position from specified datum features and between related features.

Positional tolerance

defines a zone in which the center axis or center plane of a feature of size can vary from true position.

Coaxial positional tolerance

is used to control the alignment of two or more holes or shafts that share a common axis.

Pattern‑locating control

locates the pattern of features as a group to specified datums.

Feature‑relating control

controls the feature‑to‑feature relationship

The feature‑relating control

orients to specified datums and does not locate

Pattern‑locating and feature‑relating zones are inspected

separately.

Conventional dimensioning and tolerancing can result in what is called

tolerance buildup

the accumulation that occurs when the tolerance of each individual dimension builds on the next.

tolerance bulidup

When using positional tolerancing there is ___________ tolerance buildup.

no

A _________________________ is a type of fastener that uses threads to fasten objects together and hold components in place.

threaded fastner

When applying geometric tolerances to a screw thread, the tolerance automatically applies to the axis established by the _____________ diameter.

pitch

_____________ faster relates to an application where two or more parts are assembled with fasteners, such as bolts and nuts, and all parts have clearance,

floating

Give the formula for calculating floating fastener. ____________________________________

MMC (hole) - MMC (fastener)

___________ fastener relates to an application where one of the parts to be assembled has a held-in-place fastener such as a stud or a threaded hole,

fixed

Give the formula for calculating fixed fastener. _______________________________________

MMC hole - MMC fastener) ÷ 2

A _______________ is a device used for inspecting a part.

gage

The feature control frame must contain a __________ modifier in order to use a gage for inspection.

MMC

The use of a ______________ tolerance zone is recommended when variations in orientation could cause the fastener to interfere with the mating part, typically used with fixed fastener applications.

projected

Draw the projected tolerance zone symbol: _____________
