LINK Systems LinkNet II - Manual (Page 19)

Section 3 Terminology
In order to fully understand and get the best use of this manual, it is strongly
suggested that this section be read!
Throughout this manual, certain terms are used to describe measurements, statistics, and actions.
Since these terms may mean different things to different people, their meaning as used by LinkNet will
be explained in this section.
• Part
- The part is the intended product of a manufacturing operation. For LinkNet this
will usually be a stamping operation. Note that this may not be the desired final
product, as more operations (even additional stamping operations) may need to be
performed on it. In other words, the part from one manufacturing process may
become the material for the next manufacturing process.
• Material - The input to a manufacturing operation from which parts are made. For stamping,
material is typically metal and may come in several forms.
• Sheet - A sheet is a rectangular (or square), flat portion of material.
• Strip - A strip is a long, narrow portion of material. It is sometimes referred to as a
“stick” of material.
• Coil - Material that has been rolled up to better facilitate automated production
processes. This type of material is typically fed to the press from a roll feeder.
• Blank - Material produced from a larger sheet, strip, or coil of material that will be
operated on to produce a part. It may be produced by cutting, shearing, or
from a previous stamping operation.
• Piece - Material usually produced by secondary operations on a blank. It is then fed
into further stamping operations.
• Off-Fall - The portion of the material that is trimmed, cut, or otherwise removed from the
material that becomes the desired part. Note that this is NOT the same thing as
scrap. For example, if feeding a die with square blanks produces a circle, the
portion of material outside the circle that is cut from the blank is the off-fall (see
Figure 3.1).
