Section G – Sawing Machines
1) Cold saws are useful in stock cutoff when length tolerances must be held as close as possible.
2) Cold saws use a circular metal blade.
3) One advantage of a cold saw is that they have a narrow kerf and do not waste much material.
4) The main advantage of a universal tilt-frame saw is that it can cut larger parts.
5) The size of the horizontal band saw is determined by the largest piece of square material that
can be cut.
6) The capacity of the horizontal band cutoff machine is determined by the:
A) Largest piece of round material that can be cut
B) Largest piece of square material that can be cut
C) Weight capacity of the roller stock table
D) Total length of the blade
7) The chip brush removes chips from the:
A) Workpiece
B) Worktable
C) Band wheel
D) Band guide
8) You are sawing a piece of material with a varying cross section. The best blade set for this
application is:
A) Wavy
B) Straight
C) Negative
D) Raker
9) Faster cutting can be obtained from which tooth pattern because of the positive rake angle?
A) Skip
B) Raker
C) Standard
2
D) Hook
10) Common cutting fluids for sawing operations include:
A) Air and oils
B) Water and oils
C) Water
D) Soluble oils and synthetic chemicals
11) If the set is gone on one side of a saw blade, the blade will:
A) Drift in the direction of the side with the set
B) Not cut at all
C) Drift in the direction of the side without set
D) Cut only one-half as fast as if it had set on both sides
12) What is the tooth spacing in inches for a 16 pitch saw blade?
A) 1/64 (.015) in.
B) 1/16 (.0625) in.
C) 1/32 (.03125) in.
D) 1/8 (.125) in.
13) Cutting speed is generally:
A) Slow in soft materials
B) Fast in soft materials and slow in hard materials
C) Fast in tough, hard materials
D) The speed that produces blue chips
14) Band tracking is adjusted by tilting or adjusting the:
A) Idler wheel
B) Tachometer
C) Tiltometer
D) Worktable
15) End grinding of the band ends before welding should be done:
A) On the pedestal grinder
B) With the teeth opposed
C) On each end separately
D) With the teeth on the same side
16) The process by which the band weld is softened to improve strength qualities is:
A) Annealing
B) Tempering
C) Forging
D) Softening
17) When grinding the band weld:
A) Grind on both sides of the band weld
B) Be careful not to grind the teeth
C) Check the thickness of the band in the grinding gage
D) All of the above
18) The band guide setting gage should be used on:
A) The same side on both upper and lower guides
B) Narrow guides only
C) The opposite sides top and bottom
D) The band guide adjustment only if the band is not available
19) After the band has been welded:
A) The teeth across the weld should be closer together for extra strength
B) Any tooth spacing will be acceptable
C) A small space should exist between the teeth across the weld
D) Tooth spacing across the weld should be the same as the rest of the band
20) Band tension is accomplished by moving and adjusting the:
A) Tensionometer
B) Drive wheel
C) Idler wheel and band tension crank
D) Variable speed pulley
21) Before operating the vertical band machine, you should:
A) Check the speed range transmission oil level
B) Check the hydraulic oil level
C) Lubricate the variable speed pulley hub
D) All of the above
22) You are sawing mild steel 6 inches thick. This will require a blade with a ________ pitch.
A) segmented pitch diamond band
B) coarse
C) fine
D) raker
23) The upper guide post should be adjusted so that:
A) One inch clearance exists between the band guide and the workpiece
B) The band guide is as close to the work as possible
C) The blades guide just touches the workpiece
D) None of the above
24) Recommended feed pressure should be determined by:
A) Experimentation
B) Counting the teeth in the band and multiplying by five
C) Using a longer pusher
D) Consulting the job selector
25) A fine pitch band should be used for material that is:
A) Thick
B) Hard
C) Soft
D) Thin
26) To ensure that the band set is adequate for a specific contour cut, you should make a test cut
on:
A) The workpiece
B) Thin sheet metal
C) A piece of wood
D) A scrap of the same material and thickness as the workpiece
27) You are preparing to saw very soft nonmetallic material that requires a smooth cut. You
would probably use what type of band?
A) Scalloped or wavy edge
B) Diamond edge
C) Fine pitch
D) Low speed band
28) Saw blade pitch is:
A) A blade coating designed to provide better cutting
B) The number of teeth per inch
C) The amount of set
D) The total number of teeth on the blade
