Machining Flashcards
Milling
To cut away metal by feeding it pass a rotating cutter. Can be horizontal or vertical.
The cutter can be changed really easily and can easily cut slots into the metal.
Routing
To cut away wood, plastics or composites by feeding it pass a rotating cutter. Can be horizontal or vertical.
The cutter can be changed really easily and can easily cut slots into the material.
Drilling
To cut holes into wood, composites, metal or plastics by a rotating machine bit secured into a drilling machine.
There are grooves on the bit which carries waste away whilst cutting.
To drill into metal you need to use a centre punch first.
Metal lathe
To cut away the metal with a tool set in place and moved along the material. It is spun in the process. 2 types- Facing off is where the end of the material is smoothed where as turning down reduces the diameter.
Can shape metals into complicated shapes.
Wood lathe
To cut away the wood by moving the tool along the material. It is spun in the process. 2 types- Facing off is where the end of the material is smoothed where as turning down reduces the diameter.
Can shape wood into complicated shapes.
Knurling
When a lathe is used to apply a pattern or indentation to the surface of a material.
Can add a grip or texture to tools.
Stamping
To cut out holes in a metal the same every time.
Pressing
To shape the metal around a mould. Place a flat sheet over the mould in the stamping press and apply pressure.
Creates multiples of the exact same product quickly and easily.
Blanking
To punch holes out of the metal such as drink cans.
Very quick process and produces multiples.
Piercing
To punch holes in to the metal such as drink cans.
Very quick process and produces multiples.
Plasma
Used to cut metals due to their electrical conductivity properties.
Can engrave or cut and is quick and easy to use.
Laser cutter
Produces a cut using the heat of light on a range of materials such as woods, plastics and composites.
Can cut or engrave and is quick and easy to use.
Press forming
Uses a punch and die from toughened steel which makes it impact resistant to heavy loads. Examples include car body panels, radiator panels and kitchen products.
Embossing
To create detailed decorative features on wood, boards, papers and metals.
Can create a raised design and adds texture.
Deep drawn
Blank discs are formed and cut into shape prior being deep drawn. It gets elongated into a can shape when deep drawn. Such as soft drink cans.
