Question 1

The purpose of a knurled finish is to increase protection from rust.

Accepted Answer

The purpose of a knurled finish is to provide a better grip and improve handling, not to protect from rust.

Question 2

Knurling increases ____________________.

Accepted Answer

friction grip

Question 3

A flat taper is used in the manufacture of ____.&#10;A) shims&#10;B) dowels&#10;C) cylinders&#10;D) drill bits

Accepted Answer

Shims often utilize a flat taper design to allow for adjustments in spacing or alignment in various applications, such as machinery or structural components.

Question 4

Chamfering&#160;is ____.&#10;A) the rounding of a corner&#10;B) the lengthening of a shaft&#10;C) the cutting of a groove&#10;D) the addition of material to a part

Accepted Answer

Chamfering is the process of rounding or beveling the edge or corner of a material, typically done to remove sharpness or to create a decorative appearance. Option B refers to elongation, option C refers to cutting a groove, and option D refers to adding material which is not related to chamfering.

Question 5

Creating an undercut is ____.&#10;A) the rounding of a corner&#10;B) the lengthening of a shaft&#10;C) the cutting of a &#34;groove&#34;&#10;D) the addition of material to a part

Accepted Answer

Creating an undercut involves cutting a "groove" or indentation into a part. It is commonly used in manufacturing and machining to create a recess or indentation for a specific purpose, such as allowing for the insertion of another component or part. The other choices do not accurately describe what an undercut is.

Question 6

It is acceptable to omit undercut dimensions if the dimensions are unimportant.

Accepted Answer

If the undercut dimensions do not affect the fit or function of the part, they can be omitted from the drawing or specifications. However, if they are critical, they must be included.

Question 7

A taper ratio of 2:1 means the diameter at one end is half that at the other end.

Accepted Answer

A taper ratio of 2:1 means that the diameter at one end is two times bigger than the diameter at the other end. Therefore, the diameter at one end is twice the diameter at the other end, which is the same as saying that the diameter at one end is half that at the other end.

Question 8

A conical taper is used in the manufacture of ____.&#10;A) shims&#10;B) dowels&#10;C) cylinders&#10;D) drill bits

Accepted Answer

Conical tapers are commonly used in the manufacture of drill bits, as the shape of the taper allows for effective cutting and drilling. Shims and dowels tend to be made using flat or cylindrical shapes, while cylinders may use a variety of different shapes for their manufacturing processes.

Question 9

The taper can be defined in terms of a taper ratio, or in terms of a taper ____________________.

Accepted Answer

The answer of The taper can be defined in terms...

Question 10

An undercut is specified using the diameter of the material before it is cut.

Accepted Answer

An undercut is specified by the diameter of the tool used to cut the material, not the diameter of the material before it is cut.

Question 11

Flat tapers are often used in making ____________________.

Accepted Answer

The answer of Flat tapers are often used in making...
