2. subtractive manufacturing technologies Flashcards
1
Q
turning
A
workpiece rotated and cutting tool moved in a controlled motion
2
Q
cutting off
A
workpiece rotated and cutting tool moved radially inward
3
Q
slab milling
A
rotating tool oriented in parallel to the surface or the part and also moved in parallel to the surface of the part and a layer is removed from surface
4
Q
end milling
A
rotating cutting tool oriented perpendicular to the part and is moved in parallel to the top surface of the workpiece to produce cavity
5
Q
points for design to manufacture
A
- allow tool access
- avoid long thin sections that cause vibration
- deep pockets also cause vibration of the tool
- holes cant change direction
- design parts easy to fixture
- avoid round as difficult to manufacture
6
Q
reasons for advanced machining
A
- strength and hardness of the material are very hard
- workpiece is too brittle to be machined without damage
- workpiece too flexible to withstand mechanical forces
- shape of part is complex
- special surface finish and dimensional tolerance reqs
- temperature rise of residual stress are not desirable
7
Q
orthogonal cutting
