Afab 110 unit 9 Questions with Verified
Correct Answers
Function of Dimensioning
size description of part, annotations to views describe the size or location of each feature
ASME Y14.5 Dimensioning and Tolerancing
primary standard that covers dimensioning
1st fundamental rule of dimensioning
complete size description must be given in drawing or product definition data set
2nd rule of dimensioning
no assumptions or manual measuring
3rd rule of dimensioning
90 degrees implied for center lines, features on center planes or axes, and corners of object
and features that appear perpendicular
what are the two primary units of measure
US customary units and SI
what lines are used in dimensioning
Dimension, extension and leader lines
Dimensional values often require symbols
true
what replaces an arrowhead for a dimension between two surfaces or features
, new dimension origin symbol
unidirectional dimension reads
most common read from bottom of drawing
aligned dimensions
read ither from bottom or right-hand side of drawing
do you need a note if all dimensions are same unit of measure?
no
what should you use for US Customary drawings
same number of decimal places as tolerance precision level
what is true about zero is dimensional values
Zero does not precede decimal point values less than an inch, but does for less than one
millmeter
You should use dots or commas to separate thousands
false
dimension line of angular dimension
curve with center at vertex of dimensioned angle
radius dimension
used for surfaces and features not fully round
spherical features
dimensioned by radius or diameter with letter S inserted before symbol
