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 metal is the metal left after cutting a shape which cannot be used for
any other job or project.
A line which is scribed is a line permanently marked on metal using a scriber.
A scriber is a hardened pointed marker used to mark lines on any given metal.
A cross section of a component that reveals the internal features.
A section line is the line that depicts the cutting plane in technical drawing.
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.
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.
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 is a rolling technique in which the pattern pivots around the equipment
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 is a program that enables a computer to perform a specific task, as
opposed to the physical components of the system (hardware).
In mathematics, a solid is a three dimensional geometric figure.
Springback is what happens when metal returns to its original shape after undergoing
compression and tension (stretching).
A square is a figure which has four equal (straight) sides.
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 are sheets of metal in standard sizes.
Standard top tool:
Standard top tool is the top forming blade on a press brake.
Stock pipe is pipe that is already rolled.
is a 2D pattern of a 3D object
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.
A sub assembly is a group of components that is part of the completed project.
Subassembly drawing is a type of drawing that shows how to
put together particular parts of the project.
Take one number away from another number to make a total.
Subtraction is a particular type of calculation in which one number is taken
away from another number to make a total.
This is the result when two or more numbers are added together.
Symbols are signs or images that communicate information in a shortened way.
A shape is symmetrical if both sides are the same when a line is drawn, or a
cut is made through its centre.
