p2-manufacture and project managment Flashcards
quality control
monitoring, checking and testing procedures used throughout production
quality assurance
procedures and policies which ensure that products meet specification criteria
making recommendations
decisions made regarding the strategy for ensuring the accuracy of commercially produced products will mainly depend on
-scale of production
- type of products made- skill level of workforce
small-scale production
great attention to dimensional accuracy,
range of measuring devices
-eg: craftspeople making bespoke furniture
medium-scale production
-eg: batch production of aircraft
-use of jigs and fixtures
-high skill levels
-CNC machines
large-scale production
eg: mass production of glass polymer
- effective machine tools,
sample testing of dimensions
Total quality management (TQM)
a system to improve QA by harnessing workforce expertise
scrum
use of workforce teams to respond quickly to issues in PD and manufacture
Critical path analysis (CPA)
analysis of stages in a project to ensure time-efficient completion
monitoring checking and testing
simple visual checks
- chemical analysis of samples
- colour matching for pigments or paints
-digital measuring devices
tolerance
level of accuracy acceptable
specific quality control methods
Go/no go gauge-
=check a single measurement for tolerance range,
= gauge is made with minimum and maximum dimension easy to use
Laser or probe:
= co-ordinate measuring machinery
-probe can check predefined measurements of finished components
-3D CAD models
digital measuring devices
-flexible measuring tool facilitate dimensional accuracy
