Selecting and Sequencing
Operations
Consideration in Facility Design:
1. selecting and sequencing
operations
2. designing tooling
3. preparing plant layout
4. designing material handling
systems
5. improving manufacturing systems
manufacturing engineers –
develop manufacturing facilities
Selecting and Sequencing
Operations
Factors in Selecting and Sequencing
Operations:
1. working in an orderly and
efficient way
2. having the right processes and
machines
Tools For Selecting and Sequencing:
1. operation sheet
2. flow process chart
3. operation process chart
operation sheets –
shows the operations needed to
produce the product
Operation Sheets:
- the operation name
- machine to be used
- tooling needed
operation –
processes that shape the product
tooling –
how the machines are set up
flow process chart –
puts the parts of the operation sheet
into logical order and finds the best
way to make an individual part
Flow Process Charts:
- describes the task to be done
- provides a code number for each
task
- identifies the machines to be used
- list tooling needed for the task
Flow process charts use symbols.
Flow Chart Symbols
Flow Chart
operations process chart –
shows the whole system together
instead of one part
Operations Process Chart:
- how each part is made
- how parts are assembled into products
- where operations and inspections fit
into a sequence
- what parts must be finished and when
