design for manufacture and project managament Flashcards

1
Q

planning for accuracy and efficiency

A

effective research
allow to be tested again
clear list of the clients essential and desirable requirements
needs to be tested against specification
evaluated for suitability and the achievable level of accuracy
clear schedule with deadlines and clear QC

Q

ensuring accuracy of prototype designs

A

heavily on a UCD approach with client feedback
pre production
- cad simulations, client feedback, peer review
production
- visual aesthetic checks, manufactured finish

Q

ensuring accuracy jn small medium and large scale production

A
  • CAD like simulation
  • sample prototypes
  • templates
  • visual aesthetic checks
  • machine maintenance and tool replacement
  • manufactured finish

Q

quality assurance

A

procedure and policies to reduce waste produced accurately within set acceptable tolerances
‘right first time and every time’
examples: sourcing materials with quality management standard, temp ranges
QC issues will decrease
CAD modelled to make sure they fit
FEA analyse the stresses in the working life
MFA check flow materials within moulding machinery

Q

project management systems
total quality management

A

remove waste and produce products right first time
stems from QA
for continual improvement
communicate procedures and understanding is essential

A

first used within software development
work in a team
achieve goals in short sprints
individuals feedback progress and issues

Q

project management systems
lean manufacture

A

reducing number of defective products through monitoring
systematic approach
elimante all waste
transport- reduce distance
inventory- reduce raw materials on site
movement- minimise movement
waiting- split evenly
over production- don’t over buy materials
over processing- don’t produce too many
defects- remove

Q

critical path analysis

A

analyse all individual stages within a project
in time order
reoragamise ofer dependencies and structure the order
longest and shortest time path

Q

quality control

A

monitoring testing checking materials
throughout the production process
- material checks- visual, chemical testing, colour matching
- dimensional accuracy- fit within set limits
- digital measuring devices- calliper +_ 0.02mm, interval sample testing
- go/no go gauge- fits within tolerance
- coordinate measuring machinery- range of pre defined measurements on finished components high accuracy
