Manufacturing Final Assessment
Machined parts can be classified as rotational or non-rotational. Which one of the operations can create
non-rotational geometries?
A. Drilling.
B. Milling.
C. Tapping.
D. Turning - Answer-Milling
A lathe can be set up to perform which two of the following machining operations?
A. Boring.
B. Milling.
C. Drilling.
D. Ultrasonic machining. - Answer-Boring
G03 can be cancelled by:
A. G00
B. G01
C. G02
D. any of the above - Answer-Any of the above
5 general physical processes by which we can shape materials? - Answer-deformation
(stretching/squeezing/bending), materials subtraction (cutting/shearing/eroding), melting and
, solidification (casting), joining (gluing/welding/fastening), material addition (building up e.g. 3D printing,
particulate processing).
4 key characteristics to rate manufacturing processes? - Answer-cost, quality, flexibility, rate
How does increasing part complexity typically impact the cost of making a part with traditional
manufacturing processes? - Answer-cost typically increases with part complexity
the cost to make a part with traditional manufacturing processes typically decreases with increasing
production quantity. Why is this the case? - Answer-The initial high set up costs such as the purchase of
custom tooling can be distributed over many more parts, thereby reducing the part unit cost.
How does product variety impact the feasible manufacturing quantity? - Answer-increasing product
variety typically reduces the economically feasible production quantity.
Why is understanding of manufacturing processes important for design engineers? - Answer-product
designs are constrained by the capabilities and costs associated with their methods of manufacture. A
sound understanding of manufacturing processes helps the designer ensure their design can be made
successfully.
Machining is one of the most versatile and widely used manufacturing processes. Select the reasons why
this is the case: - Answer-- it can be applied to parts with a broad range of shapes and sizes
- can be used to make relatively complex parts
- generally machining does not require custom tooling which means we can start making parts quickly
- compatible with a range of materials
- produces parts with high accuracy and good surface finish
Despite being one of the most versatile and widely used manufacturing process, machining has several
limitations. Select which limitations apply to machining: - Answer-- it generates a lot of scrap chips
