Characteristic
A measurement to be made of an object, for example, gap, flush, radius, angle,
depth, height, width, roughness, chamfer, burr, proud. A feature will typically
have a number of characteristics measured.
Checkplan
A set of Groups which describe the list of features which need to be measured
on an object.
Feature
A feature is a point on an object that is to be measured. It can have a number of
measurements depending on what characteristics are to measured,
e.g. Gap and Flush
FOV7, FOV15, FO-
V40, FOV80
The GapGun can have a number of different heads to measure different sized
features. The FOV, Field Of View defines the length of the feature to be scanned
in millimetres.
GapGun Pro
GapGun Pro is an improved highly flexible and configurable handheld measure-
ment system designed to deliver enterprise level product build quality checks.
GapGun MX+
GapGun MX+ is a flexible and configurable handheld measurement system de-
signed to deliver enterprise level product build quality checks.
Hex Tool
A demonstration artefact which exhibits all of the pre-defined tools measured by
the GapGun Virtual Tools library.
Group
A set of related Features, for example the features to be measured on one side of
an object. A second Group could be added for a similar object or mirrored to
measure the other side of an object.
Object
The object is the target of the measurements. It may have multiple features that
are to be measured.
e.g. The Hex Tool has 21 features that can be measured.
SPC3D
PC based application software to create Checkplans, to manage delivery of
Works Orders to GapGuns, to retrieve measurements made and to customize
Virtual Tools.
Standoffs
To improve reliability and repeatability, standoffs can be used to help the opera-
tor place the GapGun in the optimal position for accurate measurement. Cus-
tomized standoffs can be constructed for particular user requirements.
Virtual Tool
The GapGun can measure a number of dimensions of a feature, for example, the
gap between two panels and the flush height difference between the panels. The
GapGun comes with a set of pre-defined Virtual Tools to measure a wide variety
of features. They are organised into Tool families: Angle, Edge, GapFlush, Posi-
tion, Radius, Rivet, Seal, Surface and Custom. These tools are described in the
Tools Appendix.
Works Order
One or more Checkplans downloaded to a GapGun to allocate a series of meas-
urements to be made on one or more objects by this GapGun. When the Works
Order is complete, the results are be uploaded to SPC3D.
