Scale:
Scale represents the ratio between the drawing and the component it represents.
When an engineering drawing is drawn to scale, all parts of the drawing relate
to this ratio.
Scrap:
Scrap metal is the metal left after cutting a shape which cannot be used for
any other job or project.
Scribed:
A line which is scribed is a line permanently marked on metal using a scriber.
Scriber:
A scriber is a hardened pointed marker used to mark lines on any given metal.
Section:
A cross section of a component that reveals the internal features.
Section line:
A section line is the line that depicts the cutting plane in technical drawing.
Section plane:
A section plane describes the surface that is created when a component is cut
through so that a portion is removed and the internal features are clearly revealed.
It can also be called the cutting plane.
Sectional view:
A sectional view (or section view) is the view that is revealed when the front
portion is removed by the cutting plane to reveal the internal features.
Sine:
The sine function is one of the basic functions in trigonometry (along with
cosine and tangent). In a right triangle, the sine of an angle is the ratio
of the length of the opposite side to the length of the hypotenuse.
Single initial pinch roll:
A single initial pinch roll is a rolling machine where only one roll
can preset the edge of a cylindrical shape.
Skid rolling:
Skid rolling is a rolling technique in which the pattern pivots around the equipment
during rolling.
Slant height:
Slant height is the length from the apex to the exterior edge of a conical shape.
Slot weld: Slot weld is similar to
a plug weld but longer in length where weld process is placed in a slot in
order to join two overlapping plates.
Software:
Software is a program that enables a computer to perform a specific task, as
opposed to the physical components of the system (hardware).
Solid:
In mathematics, a solid is a three dimensional geometric figure.
Springback:
Springback is what happens when metal returns to its original shape after undergoing
compression and tension (stretching).
Square:
A square is a figure which has four equal (straight) sides.
Square root:
The square root (
)
of a number is another number which, when multiplied or squared, is equal to
that number eg 5 is the square root of 25 because 5 x 5 = 25.
Square to round:
Square to round is the term given to a shape which changes from one form to
another, specifically, from square to round.
Standard plates:
Standard plates are sheets of metal in standard sizes.
Standard top tool:
Standard top tool is the top forming blade on a press brake.
Stock pipe:
Stock pipe is pipe that is already rolled.
Stretch out:
Is
is a 2D pattern of a 3D object
.
Stroke adjustment:
Stroke adjustment is the amount of movement up or down of a blade or die block
on a press brake which can be altered to suit material thickness.
Subassembly:
A sub assembly is a group of components that is part of the completed project.
Subassembly drawing:
Subassembly drawing is a type of drawing that shows how to
put together particular parts of the project.
Subtract:
Take one number away from another number to make a total.
Subraction:
Subtraction is a particular type of calculation in which one number is taken
away from another number to make a total.
Sum:
This is the result when two or more numbers are added together.
Symbols:
Symbols are signs or images that communicate information in a shortened way.
Symmetrical:
A shape is symmetrical if both sides are the same when a line is drawn, or a
cut is made through its centre.
