Production Part Approval Process Objectives: Understand when PPAP submissions are required Understand requirements for PPAP submissions Understand the different PPAP submission levels Understanding of the forms used for PPAP submissions Understanding where the PPAP submission fits into the APQP cycle
The Purpose of PPAP
is to determine
A) If all customer engineering design records and specification requirements are properly understood by the supplier (Customer and Supplier have a common understanding of Customer requirements )
B)The process has potential to produce parts consistently meeting the requirements during an actual production run at the quoted production rate (Is the process capable of meeting customer requirements during on going production process)
Applicability of PPAP
PPAP shall apply to External and internal suppliers sites of:
Bulk Material Production Material
Production Parts Service Parts
For Bulk material PPAP is not required unless asked by the customer.
A supplier of production parts / service parts shall comply with the PPAP requirements unless the same is formally waived by the Customer (documented evidences should be available)
Application
AIAG PPAP manual defines when PPAP submission is required
New part
Correction to discrepancy in previous submission
Design or process change
Change in source of subcontracted materials or services
transfer or rearrangement of tooling & equipment
Something Changed
WHEN A PPAP IS REQUIRED ?
A PPAP is required to be submitted in the following conditions also :
For example, other construction as documented on a deviation (permit) or included as a note on the design record and not covered by an engineering change only applies to tools which due to their unique form or function, can be expected to influence the integrity of the final product. It is not meant to describe standard tools (new or repaired)., such as standard measuring devices, drivers (manual or power), etc.
WHEN A PPAP IS REQUIRED ?
Refurbishment means the reconstruction and/or modification of a tool or machine or to increase the capacity, performance, or change its existing function (Not normal maintenance, repair etc..) Rearrangement is defined as activity which changes the sequence of product/process flow from that documented in the process flow diagram (including the addition of a new process). minor changes to add to safety requirements can be made with out customer approval, provided these changes does not lead to a change in the process flow sequence
WHEN A PPAP IS REQUIRED ?
Production process tooling and/or equipment transferred between buildings or facilities in one or more locations. Suppliers are responsible for approval of subcontracted material and services that do not affect customer fit, form, function, durability, or performance requirements.
WHEN A PPAP IS REQUIRED ?
For product that has been produced after tooling has been inactive for twelve months or more, Notification is required when the part has had no active purchase order and the existing tooling has been inactive for volume production for twelve months or more . The only exception is when the part has low volume e.g. service or specialty vehicles. However, a customer may specify certain PPAP requirements for service parts.
WHEN A PPAP IS REQUIRED ?
Any change after, which affects customer requirements for fit, form, function, performance, and/or durability requires notification to the customer. NOTE: The fit, form, function, performance, and/or durability requirements should be part of customer specifications as agreed on during contract review.
WHEN A PPAP IS REQUIRED ?
These changes would normally be expected to have an effect on the performance of the product.
WHEN A PPAP IS REQUIRED ?
For change in test method, supplier should have evidence that the new method provides results equivalent to the old method.
Methodology
Buyer enters PPAP submission date on purchase order
Approver determines submission level
default level 3
Supplier submits PPAP
Approver determine part submission status
Approver evaluates PPAP package
Notify supplier and manufacturing of status
PPAP Process Requirements
SUBMISSION TO CUSTOMER LEVELS OF EVIDENCE Submission Levels The supplier shall submit the items and/or records specified by the level as requested by the customer. Level 1 Warrant only (and for designated appearance items, an Appearance Approval Report) submitted to the customer. Level 2 - Warrant with product samples and limited supporting data submitted to the customer. Level 3 Warrant with product samples and complete supporting data submitted to the customer. Level 4 Warrant and other requirements as defined by the customer. Level 5 - Warrant with product samples and complete supporting data available for review at the suppliers manufacturing location.
PPAP Process Requirements
SUBMISSION TO CUSTOMER LEVELS OF EVIDENCE
Submission Levels
The supplier shall use level 3 as the default level for all submissions unless specified otherwise by the responsible customer product approval activity. A supplier of bulk material only shall use level 1 as the default level for all bulk material PPAP submissions unless specified otherwise by the responsible customer product approval activity.
The customer will identify the submission level that will be used with each supplier, or supplier and customer part number combination. Different customer locations may assign different submission levels to the same supplier manufacturing location.
All of the forms referenced in this document may be replaced by computer-generated facsimiles is to be confirmed with the responsible part approval activity prior to the first submission.
