Looking For Engineering Specifications

Defining a process

Products of the process

amount of recyled pellets generated [kg]

delivery rate: gas tanks/day received

processing rate: gas tanks/hr recycled

weight of gas tank [kg]

dimensions of gas tank [in]

Size of gas tank [m3]

Process map

Once process steps are identified, what machines will help with each step -- specialized equipment? What are the machine specifications? (e.g. size, power rating, etc.)

mechanisms per step or task

constraints per step or task

outputs per step or task

inputs per step or task

Steps/task

Tasks that need to be done

Maintenance

will # of part defects be affected?

$/minute? Does the factory use a metric like this?

work/hr (i.e. if work is more organized will more work get done in less time?)

cost of labour [$/hr] (will this be affected if PM is done on weekends?)

more steady runtime? (duration of periods w/o downtime) [parts/hr]

preventive vs. predictive maintenance -- manual recommendations [tasks/day/wk/month/quarter/bi-annual/annual, etc.] vs. studied behaviour of the machine [cause and effect]

downtime cause and time [time of incident, duration of incident, machine failure issue, etc., date, hrs, cause codes, etc.]

manual forms vs. automated forms and ensuing potential analysis [#forms/day/wk/month/quarter/year]

Quoting and order processes

delivery time success [hrs, days from estimate]

turnover rate of quotes to JO

accuracy of quotes ($ quoted / $ spent)

# of redundant steps or tasks

time/task [hrs, minutes]

# of decisions being made

# of people involved

Who is doing what task (labour rate - $/hr)

How is the JO que managed? -- # of jobs waiting, # of jobs finished, time/job, setup time, etc.

# of quotes processed per day

# of tasks

Optimizing space

5S

transportation of parts?

orientation of parts

time associated with each?

personnel requirements?

crane

manual

forktruck

storage of parts

weight of parts [kg]

ease of reach [inches]

storage capacity

footprint

# of different types of parts

frequency of orders? [daily, weekly, monthly, etc.] and size of orders [$, kg, sqft, etc.]

size of parts (l x w x h) [inches]

# of parts needed vs # of parts "there" -- if there is no standard, inquire to establish a potential standard, then monitor it and adjust it accordingly

# of walking paths -- stages in the path, etc.

walking path [meters]

footprint [sqft]

proximity "distance" [meters]

Making an RP model and product line

Cost

design [hrs, $?]

raw materials [kg, # pkgs, $, etc.]

labour [hrs, $/hr]

machine time and depreciation [hrs, $, etc.]

Size

Amount of detail [# windows, etc.]

layer height [mm]

wall thickness [mm]

l x w x h [mm]

process and machine type [e.g. 3D printing]

materials

coating [ZP...]

powder [ZP150]

ink [HP...]

binder [ZP...]
