What is chip forming cutting?
Material removal that produces chips
Material removal that produces no waste
Cutting using water or laser
Non-mechanical removal of material
Which of the following is a non-chip forming cutting method?
Milling
Water jet cutting
Turning
Drilling
Continuous, discontinuous, and built-up edge are types of:
Tool geometries
Chips
Dies
Cutting fluids
Shear strength describes a material’s ability to:
Resist forces parallel to its surface
Resist bending forces
Resist compression
Resist twisting
Work hardening occurs due to:
Plastic deformation at low temperature
Melting and resolidifying metal
Heating above recrystallization
Hammering at red-hot temperature
Which cutting process typically does not produce chips?
Turning
Grinding
Laser cutting
Milling
Which should be checked before cutting operations?
Machine capacity and clearance
Tool color
Operator’s height
Air pressure in tires
In punching, the die is located:
Below the workpiece
Above the punch
To the side of the punch
In front of the feed roller
The outer surface of a bend is under:
Compression
Neutral stress
Tension
Shear
The neutral axis in bending is:
Point of max tension
Surface not changing length
Outermost surface
Compressed region
Hot working is performed:
Below recrystallization
Above recrystallization
In vacuum
Room temp
An advantage of hot working is:
Creates strain hardening
Refines grain structure
Increases residual stress
Reduces ductility
Workpiece protection can be improved by:
Removing film
Using scrap/film backing
Heating surface
Soaking in acid
Rolling machines typically have:
One roller
Two rollers
Three rollers
Four rollers
Why pre-set ends before rolling?
Prevent flats
Reduce tool wear
Cool rollers
Align axis
