Custom Manufacturing Oldest production
system Used to produce a
smaller number of products to a customer’s order
Highly skilled workers machines to produce individual parts
Examples – spacecraft, stamping dies, special purpose machines

Continuous Manufacturing Special purpose machines are used to
produce large quantities of products Products have limited variationsUniform parts flow from station to
station Semiskilled workers operate the
stations Examples – automobiles, household
appliances, furniture, paper, and lumber

Intermittent Manufacturing Used when continuous manufacturing is not practical
Producing products in lotsAll of the parts are processed through the station together
Often referred to as job-lot manufacturing

Flexible Manufacturing Use of special tools and machines Computer-controlled machines allow
production run to be smallReduced set-up time Increased quality control with the use of the
computerLots as small as one product can be
produced at the cost of continuous manufacturing

Just-In-Time Manufacturing Computer-based monitoring system Developed in JapanJIT stresses effective use of resourcesFocus is placed on eliminating tasks, such as
transportation, inspection, and storage which are wasteful
Raw materials arrive JIT for production, parts are produced JIT to be assembled, and products are produced JIT to meet the customer delivery orders

HOW TO CHOOSE BETWEEN THEM
COMPONENTS OF MANUFACTURING SYSTEM
CONTD….. • How easy or difficult will it be for the
employees, managers and owners to implement and maintain the manufacturing system?
• How much will the manufacturing system cost, and what can you afford to spend?
•Will the cost efficiency from the manufacturing system resolve into enough of a saving of cost, to benefit the cost of the program?

Application of FMS
Metal-cutting machiningMetal formingAssemblyJoining-welding (arc , spot), glueingSurface treatmentInspectionTesting
FMS different approaches
The capability of producing different parts without major retooling
A measure of how fast the company converts its process/es from making an old line of products to produce a new product
The ability to change a production schedule, to modify a part, or to handle multiple parts
Advantages of using FMSTo reduce set up and queue timesImprove efficiencyReduce time for product completionUtilize human workers betterImprove product routingProduce a variety of Items under one roofImprove product qualityServe a variety of vendors simultaneouslyProduce more product more quickly
FMS ExampleThrough the use of reprogrammable tooling in the body shop, standardized
equipment in the paint shop and common build sequence in final assembly, Ford can build multiple models on one or more platforms in one plant.
In the body shop, where the sheet metal comes
together to form the vehicle’s body, flexibility
means more than 80 percent of the tooling is
not specific to one model. It can be
reprogrammed to weld a car or a truck or a
crossover of similar size.
Body Shop
In the paint shop, flexibility means robotic
applicators are programmed to cover
various body styles – as they move through the
paint booth – with equal precision. This results in
minimizing waste and environmental impact
while maximizing quality.
Paint Shop
In the final assembly area, flexibility means the build sequence is
the same among multiple models on
one or more platforms allowing for efficient utilization of people
and equipment.
Final Assembly
Illustration example of a FMS
Disadvantage of using FMS Limited ability to adapt to changes in
product or product mix (ex:machines are of limited capacity and the tooling necessary for products, even of the same family, is not always feasible in a given FMS)
Substantial pre-planning activity Expensive, costing millions of dollars Technological problems of exact component
positioning and precise timing necessary to process a component
Sophisticated manufacturing systems
Development of FMS Several actions must be decided on before you
can have a have a FMS. These actions include. Selecting operations needed to make the
product. Putting the operations in a logical order. Selecting equipment to make the product. Arranging the equipment for efficient use. Designing special devices to help build the
product. Developing ways to control product quality.
