Q

When a shoulder is to be turned close to the end of the workpiece, use a scale and

A

Hermaphrodite caliper to measure location

22
Q

The bent leg of a hermaphrodite caliper is placed against the _____ of the workpiece

23
Q

In order to lay off shoulder lengths more accurately when making more than one identical, use a

A

Parting tool

24
Q

Filleted shoulders are turned with a _____ cutting tool

A

Round nosed

25
Different size fillets are made by changing
The nose radius on the cutting
26
Square corners on a shoulder are needed when
Other machine parts will be mounted against them
27
Undercuts always ensure
Square corners
28
Knurling operations always
Deform the workpiece surface
29
A 21 pitch knurling tool will produce a(n) _____ grade knurl
Medium
30
On a finished work surface, filing is usually done to
Remove tool marks and other irregularities
31
The split nut assembly is used only when
Cutting threads
32
Never engage the split nut assembly
When another automatic feed mechanism is in operation
33
The distance from a point on one thread to the same point on the next thread parallel to the screw axis is the
Pitch
34
The distance which a point on one thread travels during one revolution of the screw is the
Lead
35
When threading long slender workpieces, they should always be
Supported with a follower or steady rest
36
American National thread angles are always
60°
37
When cutting American National threads, the compound rest should always be set at an angle of
29°
38
The part of a lathe which can perform the same functions as a thread stop is the
Micrometer collar
39
How many divisions are marked on a thread dial indicator?
8
40
In cutting a right hand thread, the cutting tool is always fed
From right to left
41
A ^5/_8 in./ft. taper often used for twist drills, reamers, end mills, and lathe centers is the
Morse taper
42
A taper whose calculation depends on its assigned number in the form of a numerator over a constant denominator of 8, 10, or 2 is a(n)
Jamo Taper
43
The basic formula for calculating a taper is
Large diameter - small diameter / Length
44
The taper turning method which requires work to be removed from the lathe for the setup is the _____ method
Tailstock setover
45
The amount of inward and outward feed on the lathe's compound rest when using the taper attachment is controlled by the
Guide bar
46
A plain taper attachment requires you to
Disconnect the crossfeed screw
47
The key to using the compound rest method for turning a taper is the fact that the compound rest
Swivels
48
When using the compound rest method for turning tapers, you will need to work with angular dimensions because
The base of the rest is graduated in degrees
49
When making cutting adjustments using the compound rest method, you must back the compound rest all the way out in order to
Have full travel
50
Along with using a series of trial cuts, the most accurate way to obtain angular settings for taper turning is the
Dial test indicator and vernier bevel protractor method
