Glossary

A
activity	Activities are discrete elements of a process. For instance, a process may begin with a viewpoint activity, followed by a move activity, and so forth.
analysis	An analysis is set of conditions, such as distance or interference, that are examined during a simulation. Analysis can be either global (i.e., applying to an entire simulation) or local (i.e., applying to a bound object, such as a track).
annotations	Annotations are notes or references to data.
assembly	See manufacturing assembly.
B
bound	An object is considered bound during a simulation or analysis when the object is associated with another object, such as a track.
C
calculated cycle time	The calculated cycle time differs from the specified cycle time for speed-based activities such as device and robot-based actions.
clash	A logical process checking whether the shuttle and the environment are in intersection or in contact.
clearance	A logical process checking whether the minimum distance between the shuttle and its environment is greater than a specified threshold distance or not.
collision	A logical process checking whether the shuttle and the environment are in intersection or in contact.
constraint	A geometrical or dimensional relation between several geometric elements of different components. It may be used to define the positioning of components.
D
distance	A logical process measuring the minimal distance between the shuttle and its environment (considered as geometrical entities).
G
Gantt chart	A Gantt chart is bar graph of a process. It shows start and stop times as well as dependencies. In V5, the Gantt chart is one of several available 2D views of the process. When a simulation is running, the time bars on the Gantt chart move in synchronization with the time.
global analysis	Global analysis applies to an entire simulation.
H
hyperlink activity	Allows the user to display a file or URL during the execution of a simulation.
I
initial state	The state (positions, colors, visibility) of all products at the beginning of a simulation. It is a consistent state of the world, used as the starting point of the simulation, from which the simulation will always begin.
interference	A logical process checking whether the intersection of the shuttle and its environment (considered as geometrical entities) is null or not.
L
level of detail (LOD)	Refers to the level of detail found in visualization settings. The higher the number, the greater the amount of detail; the lower the number, the less detail.
links	Shows the relationship or precedence between activities.
local analysis	Local analysis is applied only during execution of the activity to which the analysis is bound.
location	A position in the space used to define the trajectory of the shuttle during its motion.
M
manufacturing assembly	A manufacturing assembly represents a collection of parts that are the result of one or more manufacturing processes, often as an intermediate sub-assembly that is be consumed by upstream processes in the product flow. Manufacturing assemblies can be created from existing parts or can initially be empty (i.e., containing no parts).
O
operation	Synonymous with activity.
P
parts	Parts, part models, part files, part geometry, and part data are terms used interchangeably throughout this documentation. Parts make up products.
PERT chart	A PERT chart is a graphical representation of a process. Each activity within the process is represented by a box. The activities have links to one another or to logical operators. In V5, the PERT chart is one of the available 2D views of the process.
pixel culling	Pixel culling is a method of controlling the level of detail. The higher the setting, the more pixels are culled, and the less detail the user sees; the lower the setting, the more detail the user sees.
Process/ Product/ Resource (PPR) tree	The PPR tree is a 2D view of the process. It appears in the same view as the Inventory Space window. It lists all the parts, products and resources required to make a specific product, plus specific applications data. It also lists, in hierarchical form, the actions required to perform the process that produces the product. In V5, PPR trees are stored in process documents and have a .CATProcess extension.
process	A process is a series of actions or activities that alter parts. The end result of a process is the creation of a product or a part of a product.
product	Products consist of parts which may or may not be grouped into assemblies. They appear in product structure documents; in V5, these documents have a .CATProduct extension. The difference between a product and a resource consists in how they are used with in a process. The end-result of the process should result in the creation of the product or products listed in the PPR tree.
product structure document	The product structure document is a key component in V5. It provides users with a way to organize product creation in a hierarchical format. Each product structure document can contain parts, which make up assemblies, which, in turn, make up products. Product structure documents have a .CATProduct extension
R
resource	Resources consist of parts which may or may not be grouped into assemblies. They appear in product structure documents; these documents have a .CATProduct extension. The primary difference between a product and a resource consists in how they are used within a process. The resources required during the process should be listed in the resource branch of the PPR tree. Many resources appear in V5 catalogs. Resources imported from catalogs cannot be broken down into discrete parts (e.g., selecting the mounting plate of a robot selects the entire robot, not just the mounting plate.)
resource behavior	A kind of physical activity that gets defined under resources in the resource tree of the CATProcess document.
S
shuttle	A shuttle is an element representing the object to be fitted or unfitted from an assembly. It is composed of an axis and list of models. The shuttle can be moved about to simulate the fitting or unfitting of the object within the assembly.
simulation	The animation of the products and resources as defined by the process.
specified cycle time	The calculated cycle time differs from the specified cycle time for speed based activities such as device and robot-based actions.
static analysis	Static analysis is when an interference object defined to do analysis is bound during the command.
T
task specification activities (TSA)	A physical activity that is defined under a resource behavior.
text activity	Allows the user to display a text dialog box during the execution of a simulation.
track	A sequence of locations forming a single path for a shuttle to follow. A track can be defined by creating locations. A track can then be simulated. During this simulation, interference detection can be performed.
two-dimensional (2D) views (or visualization)	In addition to the PPR tree, V5 offers users two ways of visualizing their assembly processes: via a Gantt chart and via a PERT chart.
V
viewpoint activity	A viewpoint activity alters the user's view of the data during the execution of a simulation.
visibility activity	A visibility activity alters the visibility of products during the execution of a simulation. Products can either disappear, change color, or alter their transparency.
voxelization	Voxels are volume pixels. They are the smallest 3D elements in a 3D image. Voxelization refers to the process of giving an image volume by using voxels.
