IME 145 FINAL EXAM QUESTIONS AND ANSWERS
What is your definition of manufacturing? Why it is an important part of our society? - CORRECT
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. - CORRECT
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? - CORRECT ANSWER✅✅Secondary
List the five traditional machining processes. - CORRECT 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. - CORRECT 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_________ -
CORRECT ANSWER✅✅size and location
When manufacturing a part, tolerances are found on a - CORRECT 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? - CORRECT 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. - CORRECT
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? - CORRECT
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. - CORRECT ANSWER✅✅linear,
angle, notes
A ________________________ is the most accurate hand held measuring device used during lab #1's
measuring exercise - CORRECT ANSWER✅✅micrometer
List the four different ways linear measurements can be obtained using calipers. - CORRECT
ANSWER✅✅outside, inside, depth, and step
All traditional machining process remove material in the form of - CORRECT ANSWER✅✅chips
List the four elements needed to perform any machining process. - CORRECT ANSWER✅✅1. work piece
2. cutting tool
3. machine tool
4. production personnel
Define the following machining term - Surface Speed - CORRECT ANSWER✅✅The surface speed is the
linear velocity between the work piece and the part.
Define the following machining term - Chip Load - CORRECT 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 - CORRECT 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. - CORRECT ANSWER✅✅Band saws and circular
saws.
What is the main purpose/use of a file when used in machining processes? - CORRECT
ANSWER✅✅used to deburr
List the four main types of work piece raw materials used in machining processes. - CORRECT
ANSWER✅✅1. block, bar, sheet
2. casting
3. forging
4. custom extrusions
What is your definition of an engine lathe? - CORRECT ANSWER✅✅creates cylindrical parts uses a
single point cutting tool
List the eight types of machining operations that can be performed on an engine lathe. - CORRECT
ANSWER✅✅turning, facing, grooving, boring, threading, drilling, reaming, and parting operations
Which axis on the lathe runs parallel to the part's length i.e., the axial direction? - CORRECT
ANSWER✅✅Z axis
Which axis on the lathe runs perpendicular to the part's length i.e., the radial direction? - CORRECT
ANSWER✅✅X axis
What holds the work piece in the lathe as it spins? - CORRECT ANSWER✅✅generally the work holding
device would be a chuck
How many graduations per turn (one revolution) are on the cross slide hand wheel? - CORRECT
ANSWER✅✅250
