What are the differences between primary, secondary, and tertiary industries? Give an example of each category |
A primary industry is one that cultivates and exploits natural resources, such as agriculture or mining.
A secondary industry takes the outputs of primary industries and converts them to consumer and capital goods. Examples of secondary industries are textiles and electronics.
A tertiary industry is in the service sector of the economy. Examples of tertiary industries are banking and education |
|
What is a capital good? Provide an example. |
Capital goods are those purchased by companies to produce goods or provide services. Examples of capital goods are aircraft and construction equipment. |
|
How are product variety and production quantity related when comparing typical factories? |
Generally production quantity is inversely related to product variety. A factory that produces a large variety of products will produce a smaller quantity of each. A company that produces a single product will produce a large quantity. |
|
Define manufacturing capability. |
Manufacturing capability refers to the technical and physical limitations of a manufacturing firm and each of its plants. Three categories of capability mentioned in the text are: (1) technological processing capability (2) physical size and weight (3) production capacity. |
|
Name the three basic categories of materials. |
The three basic categories of engineering materials are: (1) metals (2) ceramics (3) polymers
A fourth category, composites, is a non-homogeneous mixture of the other types and therefore is not a basic category. |
|
How does a shaping process differ from a surface processing operation? |
A shaping process changes the geometry of the work material (machining or forging)
A surface processing operation does not alter the geometry, but instead alters surface of the work (painting or plating). |
|
What are two subclasses of assembly processes? Provide an example process for each subclass. |
The two subclasses of assembly processes are: (1) permanent joining. Examples of permanent joining include welding or adhesive bonding.
(2) mechanical fastening. Examples of mechanical fastening include threaded fasteners, such as nuts and bolts, and rivets. |
|
Define batch production and describe why it is often used for medium-quantity production products. |
Batch production is where groups, lots, or batches or materials or parts are processed together through the manufacturing operations. All units in the batch are processed at a given station before the group proceeds to the next station. In a medium or low quantity production situation, the same machines are used to produce many types of products. Whenever a machine switches from one product to another, a changeover occurs. The changeover requires the machine setup to be torn down and set up for the new product. Batch production allows the changeover time to be distributed across a larger number of parts and hence reduce the average operation time per part. |
|
What is the difference between a process layout and a product layout in a production facility? |
A process layout is one where the machinery in a plant is arranged based on the type of process it performs. To produce a product it must visit the departments in the order of the operations that must be performed. This often includes large travel distances within the plant. A process layout is often used when the product variety is large the operation sequences of products are dissimilar. A product layout is one where the machinery is arranged based on the general flow of the products that will be produced. Travel distance is reduced because products will generally flow to the next machine in the sequence. A product layout works well when all products tend to follow the same sequence of production. |
|
Name three departments that are typically classified as manufacturing support departments. |
A common organizational structure includes the following three manufacturing support departments: (1) manufacturing engineering (2) production planning and control (3) quality control. |
