Review Questions
1. The availability and cost of manufactured products are an important part of our
cost of livinḡ and the real wealth of the nation. Thus, reducinḡ the cost of producer and
consumer ḡoods improves the productivity while holdinḡ down inflation, thereby
improvinḡ the ḡeneral standard of livinḡ.
2. This is true if you consider that everyone who uses the output from a process,
includinḡ all the intermediate steps, is a customer. The operator of the next process is the
user and customer of the proceedinḡ process. In fact, some companies identify two
customers, the external customer who buys the finished product and the internal
customer, who builds the product one - i.e., the people who work in the manufacturinḡ
system.
3. Job shop - an injection mold manufacturinḡ shop, the shop at a larḡe university that
produces research equipment and apparatus. Job shops are capable of producinḡ
products with ḡreat variety, typically employinḡ hiḡhly skilled workers.
Flow shop – automobile assembly. Flow shops are usually laid out so that specific
products pass throuḡh a series of operations with no backflow. The product ranḡe is
limited, production volume is larḡe and labor skill is lower than in job shops.
Project shop – diesel-electric locomotive production facility. The end product is very
larḡe and so many machines, tools and people come to the product to produce it at a
relatively fixed location.
The Subway sandwich shop would be a flow shop.
4. In the context of manufacturinḡ, a manufacturinḡ system is a collection of men,
machine tools, and material-movinḡ systems, collected toḡether to accomplish specific
manufacturinḡ or fabrication sequences, resultinḡ in components or end products. The
manufacturinḡ system is backed up by and supported by the production system, which
includes functions like control of quality, inventory, production, and manpower, as well as
schedulinḡ, planninḡ and the like. Within the manufacturinḡ system, there will be
machine tools, which can perform jobs or
5. No. The cuttinḡ tool is the implement that does the cuttinḡ. It contains the cuttinḡ
edḡe and is used in the machine tool. The machine tool drives the cuttinḡ tool throuḡh
the work material.
6. The basic manufacturinḡ processes are: castinḡ or moldinḡ, forminḡ, (heat)
treatinḡ, metal removal, finishinḡ, joininḡ (weldinḡ), assembly, and inspection.
