A process of producing a metal object from metal powders by compaction and sintering.
What is PM Powder metallurgy
100
A process in which the distorted grain structure of metals that are subjected to mechanical deformation is replaced by a new strain-free grain structure during annealing.
What is Recrystallization?
100
The relative speed between a cutting tool and workpiece in a machining operation.
What is Cutting speed?
100
A condition in which a metal being machined adheres to the point or cutting face of the tool, becoming in effect a new rough cutting edge of the tool.
What is a BUE or built-up edge-
100
When the tool geometry, cutting speed, and depth are correct these should be shaped like “9”s
What are chips
200
The process of making a solid shape in a die by using punches to press together loose powder or a blend of powders; also called molding.
What is Compaction
200
The relative ease of machining
What is Machinability
200
A term referring to any of several materials used in cutting metals, such as cutting oils, soluble or emulsified oils (water based), and sulfurized oils.
What is Cutting fluid
200
the process of removing unwanted material from wrought (rolled) stock, forgings, or casting to produce a desired shape, surface finish, and dimension
What is Machining
200
Work feeds into the cutter and can be moved in 3 axes
What is Milling
300
A compacted mass of usually fine material such as metallic powder used in powder metallurgy.
a green compaction
What is a Briquette
300
The proper shape of a cutting tool that makes it work effectively for a particular application.
What is Tool geometry-
300
The distance that a cutting tool moves in either one revolution (feed per revolution) or in one minute (feed per minute) in a machining operation.
What is Feed rate-
300
Workpiece is stationary while a multi-tooth cutter is moved across the surface
Each tooth cuts progressively deeper
What is Broaching
300
Piece is turned on this and the cutting tool is stationary
What is a Lathe
400
A process of fusing compacted material such as metal powders into a solid piece by applying heat sufficient to bond, but not melt, the particles.
What is Sintering
400
Atomization
Chemical methods
Electrolysis processes
Are all ways of making this.
They are ways of producing metal powders
400
The thickness of the layer of material sheared from a workpiece by a cutting tool in a machining operation.
What is Depth of cut-
400
This process uses rough surfaces or powers to achieve the surface desired.
What is grinding
400
Work reciprocates while tool is stationary
What is planing
500
The process of slow movement of atoms resulting in the intermingling of atoms or other particles within a metal.
Daily double
What is Diffusion
500
Lower corrosion resistance
Reduced plastic properties
Ductility
Impact strength
are all Disadvantages of this metal forming process.
What is PM
500
the advancement of the cutting tool along the workpiece (for lathes) or the advancement of the workpiece past the tool (for milling machines
What is Feed Motion
500
Work is supported by a work rest between a large grinding wheel and a smaller feed wheel
What is Centerless Grinding
500
What happens sometime if a piece is cold worked too much. It becomes ............
