Machining Flashcards
Machining provides
final shape
Dimensions/tolerances
finish
what is the difference between machining and the other removal processes
Machining is the final step while the rest are the pliminary steps
What is machining
A material removing process in which material is removed by sharp cutting tool
What is special about machining
Most versitile with high procession adn accuracy possible
What is Precision vs Accuracy
Precision- how many times the job can be done repeatedly
Accuracy- how close the measurement is to the proper value
what are the 2 classifications of machined parts
Rotational
non rotational
What are the 2 main types of rotaional parts
Cylindrical or disk shaped
What are the 2 main types of non rotational parts
Block or plate like
what produces the chariteristic part geometry
ther relitive motion between tool and work peice
shape/form of cutting tool
what are the 6 processes to generate shape
straight turning ( parrelle to straight edge)
Tapeer turning (cutting on an angle)
Countour turning (Cutting om a curve)
plain milling (Cutting on the face of an object)
profile milling ( cutting the edges of an object)
what is important in shape generatioN
part shape has to comply with tool geometry
what are some examples of forming and generating
cutting threads
slot milling
braching
drilling
advantages of machinhing
most materials can be machined
infinate vareity of part shapes and geometric features
good dimensional accuracy and procission
good surface finish
what are the 2 different cutting tool classificatiions and where are they used
single point tools (turing)
Multiple edge cuutting tools (drilling/ milling)
What are the 7 elements of single point tool geometry
End cutting edge
nose radius
side cutting edge angle
side rake angle
side relief angle
end relief angle
back rake angle
