Exam 9: Dimensioning Conventions and Surface Finishes

The surface texture for manufacturing processes is specified on working drawings through:

When parts of a drawing align on a common radial centerline, _____ coordinate dimensions are used.

Chords, arcs, and angles should all be dimensioned the same way.

Imagine that you need to record a dimension value of nine and one-half millimeters. What is the correct way to record this dimension according to ASME standards?

When rectangular coordinate dimensioning is used, the baseline is assigned a value of:

Imagine that you need to record a dimension value of one thousand millimeters. What is the correct way to record this value according to ASME standards?

What symbol should you use to indicate that the lay is perpendicular to the line representing the surface to which the symbol is applied?

The two types of working drawing dimensions include _____ dimensions.

The symbol _____ may be used to indicate a nondirectional lay.

Chords are dimensioned with:

Unidirectional dimensions are read from the _____ of the drawing.

A flat internal corner would be considered a:

What term refers to the total acceptable variation within a dimension?

Extension lines should always touch the drawing.

What is a danger of producing surfaces that are too rough?

What term refers to the primary direction of the surface pattern made by machine tool marks?

You should always dimension to hidden lines.

When tabulated outline dimensioning is used, the X-Y distance of each plotting point on a contour line is tabulated on an X-Y coordinate chart.

Dimensions should be spaced as closely as possible.

Very small radii are dimensioned with the use of an apex.
