Glossary

A
actual	difference between the direction of a ply and the delta or deviation angle.
C
core	insert enabling to stiffen the part.
core sampling	piercing of the part at one point to get the laminate.
D
deformation	a producibility analysis mode based on the angle between the two vectors of the fiber mesh.
delta	angle of deviation computed when performing a producibility analysis, that is angle between the transferred theoretical rosette and the actual fiber direction (along the X axis).
deviation	a producibility analysis mode based on the angle between the x axis of the transferred rosette and the x axis of the fiber mesh.
draping direction	direction whereby the plies are laid on the mold.
E
EEOP	Engineering Edge Of Part: engineering outer boundary of the plies.
EOP	Edge Of Part: outer boundary of the plies.
ETBS	Edge To Be Staggered: common edge between two adjacent zones.
I
IML	Inner Mold Line: top surface of the Composites part.
ITP	Imposed Thickness Point: connection point between transition zones, and zones on which the user wants to impose a thickness.
L
laminate	number of layers per association material / direction for one zone.
M
MEOP	Manufacturing Edge Of Part: manufacturing outer boundary of the plies.
P
ply	piece of fabric.
producibility	simulation of the fibers behavior to detect manufacturability problems.
R
rosette	defines the axis (X, Y, Z) in which the directions are stored.
S
sequence	manufacturing notion. Set of plies that the machine puts on the mold in one path.
stack-up file	file containing the stacking order of the Composites part.
staggering	ply drop-off to avoid ply build-up.
strategy point	point used to start the circular propagation of the fibers in the producibility tool.
T
transition zone	zone defining the geometric area of the ply drop-off between two zones.
Z
zone	conceptual definition of the Composites part. Geometrical area in which the laminate is constant.
