QUESTIONS WITH SOLUTIONS GRADED A+
◍ High or low volume production?Investment Casting.
Answer: High-Volume- a form of sand casting that can be used to create
relatively intricate shapes with good accuracy.
◍ Coincidence constraints.
Answer: can occur between two lines, two points, or between a point and a
line
◍ Layout drawings.
Answer: A formal drawing that shows a device in its assembled state with
all of its parts identified
◍ Measure Circle.
Answer: This measure command returns the center and diameter of a
circle,such as a hole diameter
◍ I have a distance in my sketch preceded by a "sigma" symbol. This means....
Answer: It is a dimension driven by a parametric formula
◍ Rolled thread.
Answer: also called knuckle thread, rolled from sheet metals
◍ Dimensions should be arranged to provide required information for
optimum readability. Dimensions should be shown in true profile views and
refer to visible outlines. Show the size and location of a hole in the view
where the hole shows up as a circle. When the hole is created in the part, it
will be located and drilled from that same view. This ensures consistency
between the design and the manufacturing of the part. Also, do not
dimension hidden features on a part. Find a view where the feature is
visible, and dimension in that view..
, Answer: Fundamental Rule of Dimensioning (5)
◍ What kinds of boundary conditions can be appliedto a finite element
model?.
Answer: stress analysis - forces or defined displacementsthermal analysis -
input temperature.objects subjected to externalforces, you must fix some of
the nodal points in space so the object is not able to moveat those points.
◍ selective assembly.
Answer: measuring parts after they're machined and matching up with
appropriate mating parts. Looser fits save money.
◍ I have an assembly with moving parts and wish to check that I have part
clearances throughout. For this I need..
Answer: Motion Study
◍ High or low volume production?Brazing.
Answer: Low-Volume- two or more separate metal workpieces are bonded
together with a metal allow filler that has a lower melting point than the
workpieces.
◍ Chamfers.
Answer: Angled cut transitions between two intersecting surfaces
◍ Degrees of Freedom.
Answer: a quantity used to represent the location and orientation of a part in
3D space
◍ Form feature.
Answer: a recognizable area of part that has a specific function or method of
manufacture
◍ Dimension Line.
Answer: A thin, dark, solid line that terminates at each end with arrowheads.
The value of a dimension typically is shown in the center of the dimension
line. *A dimension line, along with its arrowheads, shows the direction and
extent of a dimension
, ◍ Free Running Fits.
Answer: Not for use when accuracy is essential. Large temp pressures, high
running speed. Heavy pressures
◍ Baseline Dimensioning.
Answer: can eliminate some of the accumulation of tolerances. In this
system, the maximum variation between two features is the sum of the
tolerances on the two dimensions from their origin to the two features
◍ total runout.
Answer: controls rotating parts relative to the datum
◍ Milling.
Answer: does a lot of stuff, uses end mill thats sharp on edges and tip to drill
◍ Through Joles.
Answer: goes completely through an object
◍ Tangent.
Answer: Touching but not intersecting
◍ Locational Transition Fit.
Answer: These fits are intended where accuracy of location is important but
a small amount of clearance or interference is permissible
◍ Base feature.
Answer: a shape that describes the overall shape of the part (or gives the
greatest functionality in a single extrusion)
◍ Bottom tap.
Answer: used when threads are needed at the bottom of a blind hole
◍ Cosmetic features.
Answer: Features that modify the appearance of the surface but do not alter
the size or shape of the object.
◍ Edge view (of a plane).
Answer: A view in which the given plane appears as a straight line
