Term
Production System
Definition
collection of people, equipment and procedures organized to accomplish the manufacturing operations of a company (or other organization)
Term
facilities
Definition
the factory, production machines, and tooling, material handling equipment, inspection equipment, and the computer systems that control manufacturing operations
Term
Manufacturing Support Systems
Definition
consist of the resources, procedures, and man power dedicated to solving the technical and logistics problems encountered in ordering materials, work flow and quality systems. Product design and business functions are also considered
Term
Low Production
Definition
1 to 100 units annually
Term
medium production
Definition
100 to 10,000 units annually
Term
high production
Definition
10,000 to millions of units annually
Term
product variety
Definition
refers to the different product designs or types that are produced in a plant.
Term
Hard product variety
Definition
when the product differs substantially
Term
There is an blank correlation between blank and blanck in terms of factory operations
Definition
inverse;product variety; production quantity
Term
Soft product variety
Definition
when there are only small differences between products and product families that share common components
Term
hard
Definition
When product variety is blank , batch production methods are typically used.
Term
Medium Quantity Production
Definition
The production rate of the equipment is greater than the demand rate of single product type. So the same equipment can be shared among multiple products.
Term
Fixed-position layout
Definition
Workers and processing equipments are brought to the product, while the product remains in a single location. This layout is used when the product is very large and difficult to move.
Term
Process layout
Definition
The equipment is arranged according to function or type. Different parts each requiring a different operation sequence, are routed through the departments in batches following a given product’s process plan. Much material handling is required and in-process inventory is typically high.
Term
Cellular Manufacturing
Definition
is designed to support a limited a limited variety of parts configurations. A part family is established (consisting of multiple products exhibiting soft product variety)
Term
Quantity Production -
Definition
involves mass production of single parts on single pieces of equipment
Term
Flow Line Production
Definition
- involves multiple workstations, and the parts or assemblies are moved through sequence to complete the product. This layout is called Product layout.
Term
Business Functions
Product design
Manufacturing planning and
Manufacturing control
Definition
Functions involved in information-processing cycle
Term
An order to manufacture an item to the customer’s specifications.
A customer order to buy one or more of the manufacturer’s proprietary products.
An internal company order based on a forecast of future demand for a proprietary product.
Definition
starts with production order which will be in one of the following forms
Term
Business functions
Product design
Manufacturing planning
Manufacturing control
Definition
Functions involved in manufacturing support systems
Term
Fixed automation features
Definition
high initial investment for custom engineered equipment
high production rates
relatively inflexible in accommodating product variety
Term
Programmable automation features
Definition
high investments in general purpose equipment
lower production rates than fixed automation
flexibility to deal with variations and changes in product configuration
most suitable for batch production
Term
flexible automation features
Definition
high investment for custom engineered system
continuous production of variable mixtures of products
medium production rates
flexibility to deal with product design variations
Term
it is dsigned to be broken apart and reused
Definition
how is reconfigurable automation different from the three listed above
Term
to lower financial risk
Definition
9 reasons for automating were listed. which one of the following was not listed as one for these reasons
Term
automation needs to be maintained and programmed
Definition
why will manual labor always be needed in manufacturing and what economic factors make manual labor a feasible alternative to automation
Term
understand the process
simplify the process
automate the process
Definition
what does the USA principle
Term
Economic point of view definition of manufacturing
Definition
the transformation of materials in to items of greater value by means of one or more processing and/or assembly operations. Manufacturing adds value to the material
Term
what significant contribution did eli whitney do?
Definition
he had a collection of special machines, fixtures, and gauges that he had developed in his factory
interchangeable parts
Term
computers
robotics
erp systems
Definition
which of the following were not components of the second industrial revolution
Term
mass productions
assembly lines
scientific management movement
electrification of factories
Definition
which of the following were
components of the second industrial revolution
Term
what is primary industry
Definition
they cultivate and exploit natural resources such as agricultural and mining
Term
what is secondary industries
Definition
converts the outputs of the primary industries into products
Term
tertiary industries
Definition
constitute the service sector of the economy
Term
what is process parameters
Definition
are inputs to the process such as temperature setting of finance, coordinate axis value in a positioning system, etc.
Term
what are process variables
Definition
outputs from the processes such as the actual temperatures of the furnace, etc.
Term
difference between closed loop systems ans an open loop control system
Definition
closed loop control systems sample the value of output variables and utilize these output values to alter the control inputs to the process. Open loop systems make no attempt to alter future system performance based on previous system performance
Term
actions performed by the cotrol systems are simole
actuating functions is very reliable
reaction forces opposing the actuation are small enough to have no effect on the actuation
Definition
under what conditions are open loop control systems appropriate
Term
safety monitoring
maintenance and repair diagnostics
error detection and recovery
Definition
what are the advanced automated functions
Term
device level
machine level
cell or system level
enterprise level
Definition
list the levels of automation found in manufacturing systems
Term
steady state optimal control system
Definition
which of the following are typically implemented as open loop control system
Term
power/plant
program of instructions
control system
process
Definition
basic components in an automated system
Term
interlock
Definition
provide a mean by which the controller is able to sequence the activities in a work cell ensuring that the actions of one piece of equipment are completed before the next piece of equipment begins its activity
Term
interrupt systems
Definition
a computer control feature that permits the execution of the current program to be suspended to execute another program or subroutine in response to an incoming signal indicating a higher priority event
Term
ADC
Definition
Analog to digital converters
Term
DAC
Definition
Digital to analog converters
Term
what is the role of a multiplexer in an older direct digital control
Definition
share the data from different control loops with the same computer
