7.5 Flashcards
what is quality control
moitoring chekcign and testign procedures used throughout production
what si qc specified by
strict guiandnace and cdocumenation against user and stakehodler requriements
what can compliance of maetrials with manfucature specification be checked by
simple visual checks
chemcial analsysis
colour matchign for pigements or pains
how may dimensioanl accuracy be checked by
digital measurrign devices
dedicate checkign equipment
itnerval sample etsting
laser measurign sensors or probes
exmaples of digital measurign devcies
micro meters
digital calipers
lcd screen tape measure
thermometers
laser distance meeters
exampels of dedicated checkign equipment
go no go gauge
exampel o finetrval sample testign
usign equipment such as profiel prjectors
how do profile prjectors work
shadow of an object projected onto a screen which then allows people to measure and shit approtietyly
how does go/ no go gauge work
geenrally two sides to the profudct
go side is the correct size and if part fits to the gauge well then accepetd
if part fits in too well, no go
if part no fit, no good
beenfits of go no go gauge
simple
accurate
no need to measure
convinenet
what can go no go gauges be used to chekc
tool werar
manfuactured aprts
bought in aprts
by usign dedicated QC equpment on sampels what else may be tested
toguhness
transparency
flammability
water resitance
what si QA
theprocedures and poclies to ensure products meet quality stadnards and specification criteria
what does qa aim to do
make sure shit is right first time
what will efefctiev qa do
reduce numebr of qc issues and rejects
eg of QA
checkign correct temp for cavity fillign in mould
rigid machiner and cutter maintains
pre prodcution cad to chek fit and assembly
FEA
MFA
moudl identification
difference between qa an qc
qc isthroughotu manfuacture qa is plannign of procedures to enusre good products
what is TQM
a system to improve QA and reduce waste and make shti right first time, by usign workforce expertise
what will tqm aim to do throughotu the whoel manfucturign process
make shti right first time
parts of TQM
All satges of design and manfuacture cosntantly montiroed and evalautaed
workforce views highligh prioritised
what are british and eurpopean standards
documents that set quality safety and other requirements for a raneg fo sevrices and producst
what is the ISO 9001
improtnat quality standard guide for manfuacturers and toher organsiations
what does ISO 9001 fuide oragnsiatiosn to do
guides people in satsifyign requirmeents of custoemrs and othe rstakehodlers who interact with product
what does followign the ISO 9001 give companies
