TECHNOLOGY
Technology is the relationship that society has with its tools and crafts, and to what extent
society can control its environment. The term is often used to imply a specific field of
technology, or to refer to high technology, rather than technology as a whole.
Technology can be most broadly defined as the entities, both material and immaterial, created
by the application of mental and physical effort in order to achieve some value. In this usage,
technology refers to tools and machines that may be used to solve real-world problems. It is a
far reaching term that may include simple tools, such as a crowbar or wooden spoon, or more
complex machines, such as a space station or particle accelerator.
The word technology can also be used to refer to a collection of techniques. In this context, it
is the current state of humanity’s knowledge of how to combine resources to produce desired
products, to solve problems, fulfill needs, or to satisfy wants; it includes technical methods,
skills, processes, techniques, tools and raw materials. When combined with another term,
such as medical technology or space technology, it refers to the state of the respective field’s
knowledge and tools. State of the art technology refers to the high technology available to
humanity in any field.
Technology can be viewed as an activity that forms or changes culture. Additionally,
technology is the application of math, science, and the arts for the benefit of life as it is
known. A modern example is the rise of communication technology, which has lessened
barriers to human interaction and, as a result, has helped spawn new subcultures; the rise of
cyber-culture has, at its basis, the development of the Internet and the computer.
Not all technology enhances culture in a creative way; technology can also help facilitate
political oppression and war via tools such as guns. As a cultural activity, technology
predates both science and engineering, each of which formalizes some aspects of
technological endeavor.

THE BAND SAW
A band saw is an electric or pedal-driven saw with a blade consisting of a long, narrow, flexible band
of toothed metal. The band (blade) rides on two wheels in the same vertical plane with a space
between them. Band saws can be used for woodworking, metal working, or for cutting a variety of
other materials, and are particularly useful for cutting irregular shapes. The radius of a curve that can
be cut on a particular saw is determined by the width of the band.
Metal-cutting band saws
When cutting metals, coolant is often used to provide a constant flow of liquid coolant over the blade.
The coolant keeps the blades cool, which adds to blade life. Wire brush-wheels are sometimes used
to remove chips and build-up from the blade as it exits the material. Metal-cutting band saws are
available in vertical and horizontal designs. These units range from manually operated machines to
fully automatic machines. Band speeds range from 12 metres per minute to 1,500 metres per minute.
Machine shop band saws come in two styles - horizontal and vertical. Small, manual shop saws
usually employ a gravity-fed blade that falls in an arc around a pivot point and are of the horizontal
style. The rate of descent is controlled by a hydraulic cylinder that has an adjustable valve. When a
manual saw is set up for a cut, the operator raises the saw by hand and leaves it in a 45 degree up
position. The material is put into the saw, clamped, the saw is turned on, and the blade slowly falls
into the material, cutting it as the band blade moves. When the cut is complete, a switch is tripped and
the saw automatically turns off.
Feed mechanisms
• Gravity feed saws fall under their own weight against a hydraulic cylinder which has a
control valve. Common in small saws.
• Hydraulic feed saws use a positive pressure hydraulic piston to advance the saw through
the work. Common in production saws.
• Screw feed employ a leadscrew to move the saw.
Fall mechanisms
• Pivot saws hinge in an arc as they advance through the work.
• Single Column saws have a large diameter column that the entire saw rides up and down
on, very similar to a radial drill.
• Dual column saws have a pair of large columns, one on either side of the work, for very high
rigidity and precision. The dual column setup is unable to make use of a mitre base due to
inherent design. Dual column saws are the largest variety of machine band saws
encountered, to the point where some make use of a rotary table and X axis to perform
complex cutting.
