Section Views
An imaginary plane that defines where the object is cut
Cutting Plane
The cutting plane passes completely through the part as a single flat plane
Full Section
True or False: Cost generally decreases with smaller tolerance
False
A final set of drawings providing all the details and information needed to manufacture and assemble a finished design.
Working Drawings
_________ are drawn where the object passes through the cutting plane. If a saw was used to cut the part, then they represent the cutting marks left by the saw blade
Section Lines
The cutting plane only passes halfway through the part
Half Section
Allowance for specific variation in the size and geometry of a part
Tolerance
A drawing of each individual part that clearly reveals all details
Detailed Drawing
True or False: Section lines are not used for thin parts rather they are filled in solid
True
For this drawing, the internal features of many parts can not be shown using a single straight cut to create the sectioned drawing
Offset Section
Which Tolerances have a higher hierarchy, General or Specific?
Specific Tolerances
A list of all parts needed for an assembly. Includes all parts manufactured and purchased. Includes balloon tag reference number, part name, part number, quantity, and material.
Bill of Materials
A multi-view technical drawing that reveals details about internal features by displaying the part as if cut by an imaginary cutting plane
Sectioned Drawing
A jagged break line is used to divide the sectioned and non-sectioned portion of the drawing
Broken-out section
Explain the difference between Hole Basis and Shaft Basis
In the Hole Basis the size of the hole is kept constant and the size of the shaft varies; the opposite is true in the Shaft Basis.
May use one or several views (multiview, pictorial, section, exploded, detail view, etc.) to clearly show how parts are assembled and interact.
Assembly Drawings
Mentioned 3 different types of section drawings:
Full Section, Half Section, Assembly Section, Offset Section, Broken-Out Section, Revolved Section, Removed Section, Special Section Conventions
What is the difference between the Revolve Section and the Removed Section View?
In the Removed Section, the sectioned drawing is not superimposed on the drawing but placed adjacent to it
Explain the difference between Clearance Fit and Interference Fit?
In the Clearance Fit the parts are toleranced such that the largest shaft is smaller than the smallest hole,
while in the Interference Fit the parts must always be forced together since the largest hole is smaller than the smallest shaft.
What details should be put in detailed drawings?
Every feature clearly dimensioned.
Tolerance specified for every dimension.
Material specifications. Finishing and surface treatment specs.
