EQUIPMENT Flashcards
what is a marking gauge
to scribe a line parallel to a reference edge or surface
used on wood
very accurate and precise , clean line
blades may become blunt
some parts may be lost marking them useless
what is a cutting gauge
Used to cut a line into wood parallel to an edge to mark the bottom of a wood work joint. The stock needs to be flat against the side of the workpiece
used on wood veneer
what is a mortise gauge
to scribe mortise joints before cutting with a chisel
used on wood
very accurate
what is a odd leg calliper
to scribe lines parallel to the edge of metal (or plastics)
what is a set square
marking out the right angle before cutting a joint
they come in 90-45-45 and 30-60-90
what is a internal and external calliper
Internal callipers have curved, inwards facing points, enabling them to measure the internal dimensions of an opening.
external callipers have straight, outwards facing points for measuring external dimensions, such as the diameter of a round object.
what is a try square
checking 90 angle
only used internal
what is an engineers square
high performing 90 angle
checking angle
used for both internal and external
what is a mitre square
marking and checking angles other than 90°. Most mitre squares are for marking and checking 45° and 135
accurate joints
what is a micrometre
measuring wires
measuring material thickness to a high degree of accuracy 0.01mm
expensive
can break easily
can be difficult to read off of
what is a veneer calliper
used for bigger objects
measuring material thickness to a high degree of accuracy 0.01mm
expensive
can break easily
can be difficult to read off of
what is a densitometer
to accurately measure the photographic (optical) density
what is a divider
to measure distances, transfer lengths from one drawing to another, and draw circles.
stiff so wont slide
what is a jig
tools that hold a cutting tool in place or guide it as it performs a repetitive task like drilling or tapping holes.
can be made from any material
can become worn over time
can be reused
all identical
makes process quicker
what is a fixture
to create a secure mounting point for a workpiece,
allowing for support during operation
increase accuracy,
precision,
reliability,
interchangeability in the finished parts.
what is a go no go gauge
checking hole size
easy to use
cheap
making holes accurate
what is a steel rule
measuring up to 300mm
rigid so wont bend and flex
not very accurate
may slip
what is a scriber
making individual lines on materials like metal and plastic
used for scoring
accurate
lines can be difficult to see
what is a marking knife
used on wood
to score a line ready for cutting
more accurate than a pencil
what is a sliding bevel
to mark or check an angle
as can be moved into ay angle
versatile
what is a centre punch
making point of metal and plastic ready for drilling
drill bit less likely to slip
accurate
may become blunt
