WITH COMPLETE SOLUTION
What is your definition of manufacturing? Why it is an important part of our
society? Answer - Manufacturing is the processing of raw materials into
finished products using machines, tools, and advanced technology.
Manufacturing is an important part of our society because it increases
economic productivity and leads to more innovation, exports, and opens up
middle-class jobs.
List the seven different categories manufacturing processes are divided into.
Answer - casting, bulk deformation, sheet1 metal forming, additive, polymer
processing, joining, machining
The manufacturing industries are classified into three different categories.
What category are companies who perform machining processes usually
classified under? Answer - Secondary
List the five traditional machining processes. Answer - sawing
turning
milling
drilling
broaching
What is an orthographic projection? List the two types of projection standards
used to create orthographic projections on drawings. Answer - Orthographic
,projections are two dimensional representations of a three-dimensional object.
The two types of projection standards are first angle projection and third angle
projection.
Dimensions are placed on an engineering drawing to describe a
feature's______and_________ Answer - size and location
When manufacturing a part, tolerances are found on a Answer - title block and
notes sections
What is the difference between variables and attributes inspection? What type
of inspection attributes are we gathering when we are measuring our parts
with dial calipers? Answer - Variable types of inspection generally take more
time and are more expensive than attributes inspection.
Define the term accuracy in terms of measuring/inspecting machined parts.
Answer - measurement result against actual value and actual value against
target value
Define the term precision in terms of measuring/inspecting machined parts.
How many more times precise do we want our measuring instrument to be
when measuring a part? Answer - Precision is the degree to which the
instrument provides repeated measurements of the same parts. You want to
be at least 10 times more precise when measuring a part.
List the three main types of dimensions placed on engineering drawings.
Answer - linear, angle, notes
A ________________________ is the most accurate hand held measuring
device used during lab #1's measuring exercise Answer - micrometer
, List the four different ways linear measurements can be obtained using
calipers. Answer - outside, inside, depth, and step
All traditional machining process remove material in the form of Answer -
chips
List the four elements needed to perform any machining process. Answer - 1.
work piece
2. cutting tool
3. machine tool
4. production personnel
Define the following machining term - Surface Speed Answer - The surface
speed is the linear velocity between the work piece and the part.
Define the following machining term - Chip Load Answer - Chip load is the size
of the chip the cutting tooth shears off the workpiece when machining
Define the following machining term - Depth of Cut Answer - Depth of cut is
the measurement of how deep the tool cuts into the workpiece during one
pass of the tool.
List the two main types of saws used in a machine shop. Answer - Band saws
and circular saws.
What is the main purpose/use of a file when used in machining processes?
Answer - used to deburr
