grams - ANSWER-What is the preferred unit of measurement when using a scale?
Any residue left behind adversely affects future use of the scale. - ANSWER-Why
should you keep the scale free of foreign residues?
Straight. - ANSWER-If you must cut out a triangle from a thin piece of metal, which type
of snips gives you the best results?
To allow seeing the cutting line. - ANSWER-When using straight snips to cut out a circle
why should the cutting direction be counter-clockwise?
straight - ANSWER-Which type of snip can you sharpen when it becomes dull?
aviation - ANSWER-If you must enlarge a small hole in a piece of metal, which type of
snips do you use?
aviation - ANSWER-If you are using the upper blade as a guide during a cutting
operation, what kind of snips are you probably using?
single - ANSWER-What type of file cut do you use to sharpen shears or snip blades?
flat - ANSWER-What type of file is best suited for common filing operations?
triangle - ANSWER-What type of file is used for filing cutters and taps?
Because the cutting teeth slant forward and the pressure on the back stroke will
probably break them off. - ANSWER-Why is pressure on the back stroke usually not
permitted when filing?
When filing very soft materials. - ANSWER-When should you use a slight pressure on
the back stroke while filing?
Near the vise jaws to prevent vibration and, if the surface is straight, parallel to the top
of the vise. - ANSWER-How should material for crossfiling be positioned in a vise?
When a finer surface is required. - ANSWER-When do you drawfile a piece of metal?
Always use a file handle. - ANSWER-What is the main precaution to remember when
using a file?
,Chipping, and cutting sheet metal, heads off screws, and flat stock. - ANSWER-What
are the correct uses of the flat chisel?
The half roundnose cuts concave grooves; the cape cuts grooves, slots, and keyways,
and chips flat surfaces that are too narrow for a flat chisel. - ANSWER-What are the half
roundnose and cape chisels used for?
To cut V-shaped grooves - ANSWER-What is the correct use of the diamond point
chisel?
Pressing too hard against the wheel and allowing too much heat to generate. -
ANSWER-When sharpening a chisel, what may soften it and cause it to lose hardness?
All-hard blade with 18 teeth per inch. - ANSWER-What type and pitch of blade do you
use when you must cut solid aluminum?
24 teeth per inch. - ANSWER-Which blade pitch gives the best results when you must
cut a 12-foot length of angle iron into 12 equal sections?
32 teeth per inch. - ANSWER-What is the recommended pitch for cutting thin wall
tubing?
To allow clearance for the rest of the blade in the saw cut. - ANSWER-Why is it
necessary for a hacksaw blade to have "set"?
(1) Alternate.
(2) Undulated (wave).
(3) Raker. - ANSWER-What are the three types of blade set?
Clamp the material in a vise, providing as much bearing surface as possible so the
greatest number of teeth on the blade will be engaged. - ANSWER-When using a
hacksaw how can you position a stock to obtain the best results?
Forward. - ANSWER-Which stroke (forward or backward) is the cutting stroke?
Scroll - ANSWER-What type of lever shear is used to make cuts on the inside of a sheet
of metal?
Because the frame of the shear never obstructs the cutting operation. - ANSWER-Why
is it possible to cut any length or width of cut with a throatless shear?
Insert the metal between the blades and cut off approximately ¼ inch of metal; square
the remaining edges by holding the trimmed edge against the side gauge and making
cuts one edge at a time. - ANSWER-Describe the procedures for squaring a piece of
metal with a manually operated squaring shear.
, When the metal isn't cutting square. - ANSWER-When do you readjust the side gauge
on a manually operated squaring shear?
For cutting a number of pieces to a specific size. - ANSWER-When do you adjust the
back gauge on a manually operated squaring shear?
The holddown is automatically lowered on the power-operated squaring shear when the
cut is made. - ANSWER-How does the operation of the holddown on a power-operated
squaring shear differ from a manually operated squaring shear?
Check the data plate to ensure the metal being cut is within the capacity of the machine,
and ensure the machine is clear of material and personnel. - ANSWER-What must you
do before operating a power-operated squaring shear?
Ketts circle. - ANSWER-If you must remove a damaged section of a stringer, which type
of power-operated saw do you select?
Reciprocating. - ANSWER-For cutting square or rectangular cutouts, which type of saw
should you select?
Because of the adjustable collars. - ANSWER-Why is the reciprocating saw able to cut
almost any shape of cutout?
Do not apply too much downward pressure on the handle - ANSWER-What action can
be taken to prevent the blade from breaking or bending when using the reciprocating
saw?
At least 2 teeth must be on the cutting surface at all times. - ANSWER-When selecting a
saw blade to use in a contour metal cutting saw, what factor concerning the pitch of saw
blade must you consider?
Width of the saw blade. - ANSWER-What factor determines the size of the inserts used
on the guide blocks of a contour metal cutting saw?
A taut tension is preferred because it prevents the blade from twisting or wavering. -
ANSWER-When adjusting the tension on a newly installed saw blade, what is the
general rule to follow?
When the saw blade runs in the guides with its back edge touching the rollers. -
ANSWER-How do you know when the saw blade is tracking properly?
The thickness of the material being cut, plus ⅛ inch. - ANSWER-How high should the
post be adjusted from the work table?
Goggles or face shield. - ANSWER-What type of safety equipment must be used when
operating a contour metal cutting saw?
