ANSWERS 2026 VERIFIED.
Outsourcing - ANS reduce: design & manufacturing costs
constraints: social impact, political implications, shipping
manufacturing goals - ANS -developments in nano materials, nano powders, composites,
shape-memory alloys
-implement most economical/environmentally friendly manufacturing methods
-adopt production methods that are flexible to rapidly respond to changing global market
demands
engineering drawings impact on manufacturing - ANS - how to manufacture the product
- how to inspect
- plant layout
- new equipment
- fixture to manufacture a part
- cost estimate
dimension lines - ANS lines with two arrows at the end
leader lines - ANS line with one arrow pointing to something
dimensioning general rules - ANS - place dimensions between views
@COPYRIGHT ALL RIGHTS RESERVED PAGE 1 OF 7
, - place smallest dimension nearest to dimension being measured
- dimension the view that best shows the shape
datum - ANS - theoretical exact point/axis/plane from the true geometric counterpart of a
specified datum feature
- reference features usually defined by the critical surfaces on a part
- these features will be the origin for dimensioning other features
- typically: flat surfaces on a part,
primary datum - ANS - planar surface that fixes spatial orientation of the part
- minimum of 3 points of contact
- can be seen as the zero-location for z-axis
secondary datum - ANS - can be seen as zero-location for x or y axis
- minimum of 2 points of contact
tertiary - ANS - minimum of 1 point of contact
- can be seen as zero-location for x or y axis
tolerances - ANS to reduce cost: widest tolerance, consider processes
expressed through: limit dimensioning OR plus/minus tolerancing
limit dimensioning - ANS max/min dimensions only are specified
plus/minus tolerancing - ANS specifies the basic size +/- tolerance values
- equal, unequal, unilateral
basic size - ANS the exact size we would prefer
