Exam 4: Manufacturing Materials and Processes

List four types of machining operations that can be per- formed on a drilling machine.

identify the type of metal or metals that are part of the given Unified Numbering System (UNS) series: -E00001 to E99999

identify the type of metal or metals that are part of the given Unified Numbering System (UNS) series: -L00001 to L99999

Discuss the results of designing a part with specifications that require overmachining.

Give the typical contents of stainless steel.

identify the type of metal or metals that are part of the given Unified Numbering System (UNS) series: -C00001 to C99999

Briefly describe the stamping process.

Name the casting technique that is referred to as "lost wax."

Name the plastic material that dates back to the late 1800s. This plastic is hard and rigid, has good compression strength, is tough, and does not absorb moisture, but it is brittle. These plastics are commonly used for the manufac- ture of electrical switches and insulators, electronics circuit boards, distributor caps, and binding material and adhesive.

Which cast iron has the internal characteristics of gray cast iron and the exterior properties of white cast iron?

Give the name of the process that works by placing material into an initial hot die where it takes the preliminary shape. As the material cools, a die that matches to the shape of the desired product forms the final shape.

In casting design, is draft added to the minimum or maxi- mum design sizes of the part?

Normally a jig or fixture is drawn as an assembly of the unit ready for use, and the workpiece or part to be held is drawn in position. How is the workpiece drawn in relationship to the jig or fixture?

Define thermoplastic.

What is another name for plastics?

Give the name of a process where resin is used to make qual- ity composite products with a smooth surface on both sides. This method places reinforcing material into a mold and then pumps resin into the mold.

Identify the term that refers to polymer-based materials that have elastic qualities not found in thermoplastics and thermosets.

What are composites?

Describe chemical machining.

Give the name of the process that uses machines to wind resin-saturated reinforcement fibers around a shaft. Part 3: Machine Processes
