Exam 4: Manufacturing Materials and Processes

Give the name of the process that uses a computer model that is traced in thin cross sections to control a laser that deposits layers of liquid resin or molten particles of plastic material to form the desired shape.

Briefly describe the metal injection molding (MIM) process.

Name the process that works by taking a sheet of material and heating it until it softens and sinks down by its own weight into a mold that conforms to the desired final shape. Vacuum pressure is commonly used to suck the hot material down against the mold.

Identify at least two uses for nodular cast iron.

What is the recommended standard finish allowance for iron or steel?

identify the type of metal or metals that are part of the given Unified Numbering System (UNS) series: -J00001 to J99999

identify the type of metal or metals that are part of the given Unified Numbering System (UNS) series: -G00001 to G99999

Define extruded.

Define ductility.

Define tensile strength.

Define carburization.

Briefly discuss the major differences between thermoplas- tics and thermosets.

Define forging.

Describe the properties of the following steel alloying ele- ments: manganese, molybdenum, and tungsten.

identify the type of metal or metals that are part of the given Unified Numbering System (UNS) series: -T00001 to T99999

What is the function of a reamer?

Identify the alloying elements in brass.

identify the type of metal or metals that are part of the given Unified Numbering System (UNS) series: -D00001 to D99999

Name the process that uses vacuum pressure to force a thin layer of sheet-reinforced polymer around a mold.

Define casting.
