一,定义
(
什么是
PPAP)
:
definition
顾客对供应商
的产品、生产条件、生产过程等方面的书面约定与认可。
PPAP is a production part approval
processused by US auto industry (GM, Ford, an d
Chrysler).
The Production
Part Approval Process (PPAP) outlines the methods
used for approval of product
ion and
service commodities, in cludi ng bulk materials,
up to and including part submission
warrant
in
the
Advaneed
Quality
Planning
process.
The
purpose
of
the
PPAPprocessis
to
ensurethat
suppliers
of
components
comply
with
the
design
specification
and
can
show
documentary evidenee that the level can
be maintained during the life of the product.
二,目的
(
aim
):
确定供方是否已经正确理解了顾客工程设计记录和规范的所有要求,并且在执
行所
要求的生产节拍下的实际生产过程中,具有
持续满足这些要求的潜在能力。
The Purposeof
PPAP is to determ ineif all customer e ngin eeri

supplier a nd that the process has
the
potential to produce product meeting these
requirements during an actual production run
at the quoted rate.
三,过程要求:

(
如果有
)
Design records are engineering
requirements for judging the acceptability of a
part characteristic. For
qualification,
every feature of the product as identified by
engineering specificatio ns or part draw in g/pri
nt must be measured. Desig n records
are con sider as, all customer and supplier design

工程更改文件
< br>(
如果有
)

Engineering Change Documents are
defined as any authorized engineering change(s)
(
authorized by Motorola

)
not yet
recorded in the design record but incorporated in
the product, part or
tooling.
3.
顾客工程批准(如果要求)
CustomerEngineeringApproval
(
If
required
)
Customer Engin eeri ng approval is the
process that provides for two way com muni cati on
between the
component supplier & the
responsible Motorola design engineering activity
and through which the supplier
requestsc on curre nee for certa in
desig nan d processcha nges.
Once
Motorola desig n engin eeri ng determ in es that
the cha nge is feasible and an engin eeri ng
approval is required, the supplier will
complete and submit the Process Change
Notification for approval.
