Question 1

Describe the newest ASME standard for dimensioning conical (cone-shaped) tapered surfaces.

Accepted Answer

The newest ASME standard for dimensioning conical (cone-shaped) tapered surfaces recommends the use of a ratio followed by the taper symbol. The ratio represents the difference in diameter in relation to the length of the taper.

Question 2

How are tapers usually specified on drawings where dimensions are given in inches?

Accepted Answer

The taper is usually specified on drawings where dimensions are given in inches by a note that gives the TAPER PER FOOT or the TAPER PER INCH.

Question 3

In the accompanying figure, provide a brief description of the process for the symbol identified as number 2.

Accepted Answer

The surface is to be produced by a nonmachining process such as casting, forging, welding, rolling, powder metallurgy, etc. There is to be no subsequent machining of the surface.

Question 4

The accompanying figure illustrates ____ forging.

Accepted Answer

A)  machined 
B)  stamped 
C)  drop 
D)  hot 
A)  machined 
B)  stamped 
C)  drop 
D)  hot

Accepted Answer

A)  standardized 
B)  finished 
C)  designed 
D)  finalized 
A)  standardized 
B)  finished 
C)  designed 
D)  finalized

Question 6

In the accompanying figure, provide a brief description of the process for the symbol identified as number 3.

Accepted Answer

Question 7

When a casting, forging, or welded part is to be finished all over, the drawing is simplified by omitting the finish symbols and adding the note: ____.

Accepted Answer

A)  ALL OVER 
B)  ALL OVER FINISH 
C)  FINISH 
D)  FINISH ALL OVER 
A)  ALL OVER 
B)  ALL OVER FINISH 
C)  FINISH 
D)  FINISH ALL OVER

Question 8

On a round piece of work, the ____ is the difference between the diameter at one point and a diameter farther along the length.

Accepted Answer

A)  radius 
B)  taper 
C)  angle 
D)  arc 
A)  radius 
B)  taper 
C)  angle 
D)  arc

Question 9

Explain what the values in the ASME surface texture system specify.

Accepted Answer

The ASME surface texture system requires

Question 10

In the accompanying figure, provide a brief description of the process for the symbol identified as number 1.

Accepted Answer

The surface may be p

Question 11

As applied to drawings, ____ denotes repetitive or random deviations from a nominal (specified) surface.

Accepted Answer

A)  surface detail 
B)  surface reference 
C)  surface texture 
D)  surface scale 
A)  surface detail 
B)  surface reference 
C)  surface texture 
D)  surface scale
