PURCHASED PRODUCT FOR PROTOTYPE
SCOPE
This procedure applies to all suppliers of Type I material for prototype. It defines submission and documentation requirements for shipment of part(s) produced by external suppliers.
DEFINITION
Type I Materials are defined as materials that become part of the product Timken sells and outside services used to produce (in whole or part) the product Timken sells.
PROCEDURE
This procedure applies to all suppliers providing new Type I prototype material to Timken Research – Prototype Development at 4500 Mount Pleasant Road, North Canton, OH 44721. All
material shall be in accordance with requirements set forth in this procedure. The intent of the Prototype activity is to assemble and test parts, processes and assembly systems, and conformance/measurement/design validation. Part approval at Prototype insures component part problems are identified and corrected to minimize the impact of part variation
upon design evaluation, manufacturing and assembly. Parts are to be made to Timken authorized drawings, templates, models and/or other engineering design records, using specified materials. For deviations from engineering requirements contact your procuring division buyer for formal authorization on a Timken Subcontractor Product/Process Change Request Form. All suppliers of prototype parts are required to have completed, documented and available for review the items listed below:
- Timken Company supplier warrant of material for prototype
- Design records
- Inspection results and inspection and/or test devices
- Material certification
- Part weight (mass)
- Serialization information
- Production material and processes
- Analysis/Development/Validation Documentation (When Requested)
- Any requirements in addition to the requirements set forth in this procedure
A Timken Supplier Warrant of Material for Prototype shall be completed in full and signed and dated by an authorized official of the supplier who is responsible for the preparation and
shipments of parts. These Warrants must be supplied to The Prototype Quality Coordinator or designate.
If parts submitted do not meet specifications, but are deemed usable by an authorized representative (This would include the Manager of Prototype Development, Prototype Quality Coordinator, or designate, and appropriate Application Engineer) of the Timken Company, the corrective action plan on the back of the warrant must be completed in full and signed by the authorizing Timken representative prior to submission and shipment of parts.
Design Records can include but are not limited to the part number, sketches, marked prints, math data, blueprints, and other auxiliary drawings. The part number, design record number, design record date, change revision number, and procuring division responsible engineers signatures, shall appear on the above except in the electronic release process.
Suppliers are responsible for performing or having performed the inspections and/or tests required substantiating conformance to specifications. Complete Characteristic Inspection shall be conducted and recorded by the supplier on five (5) parts unless otherwise specified by the procuring division. On all parts produced in excess of the quantity specified in the above, key product characteristic inspection points specified on the design record shall be measured/checked for conformance to the requirements. A key product characteristic is any characteristic labeled as a safety, critical, major, or special characteristic.
Submission requirements because of an engineering change or a correction to the original part require only the changed portion and any other area affected by the change be inspected. The results shall be submitted to the procuring division on the resubmission of a Timken Supplier Warrant of Material for Prototype to document the verification and conformance to specifications and requirements resulting from the change.
The supplier is responsible for the acceptability of each detail component and shall furnish evidence of conformance to requirements when requested to do so by the procuring division. When an inspection and/or testing device such as a gage, fixture, checking-aid, or template is used to inspect and/or test a part, the supplier is responsible for inspecting and verifying that the device has been constructed to the same engineering release and change number as the part being inspected and/or tested.
The material certification is a document from the material producer that states manufacturing location, lot number, product identification number, product name, date(s) of test and test data required to show compliance to the Timken product specifications.
The supplier is to furnish part unit weight (mass) data for each individual part number supplied to Timken. The weight is to be expressed in kilograms to the third decimal (0.000) and reported on the Supplier Warrant of Material for Prototype. A minimum of ten (10) parts shall be individually weighed and the results averaged. In instances of parts weighing less than 0.1 kg, a quantity of ten (10) pieces should be weighed together and the results divided by ten for reporting purposes. If the quantity of parts ordered is less than ten, weigh the available quantity to establish an average weight. Parts are to be free of coolants, rust inhibitors, cutting oils, lubricants, etc. when being weighed.
Parts shall be numerically serialized and referenced to test/inspection results. Serial numbers shall begin with PT-0001 and continue in sequence through the last part shipped unless a different serialization procedure has been called for on the design record/print or agreed upon by the Timken Company procuring division and supplier in writing. Part serialization is required unless otherwise specified in writing by the procuring division.
When production material and the complete production process are utilized the supplier should begin to complete requirements of the Production Part Approval Process (PPAP).
Procuring Division must define if Design Validation and/or Product Validation must be included on the Prototype Purchase Order. Details of the requirements are reflected in the Statement of Requirements or other engineering documentation.
Validation is the formal process of confirming, through analysis, demonstration, inspection, and test that the product meets all of its specified requirements.
Design Validation confirms that the product design meets its technical requirements through analyses, demonstrations, inspections and/or tests performed without including the effects of manufacturing variation.
Product Validation confirms that the product design meets its technical requirements, through analyses, demonstrations, inspections, and/or tests performed including the effects of manufacturing variation.
In addition to requirements set forth in this procedure The Timken Company procuring division retains the right to demand additional test and/or inspection and/or submission requirements as set forth by the Timken Company procuring division prior to part submission.
The procuring division will specify the submission requirements. Suppliers not informed of the submission requirements should follow the procedure specified below Level 1. Parts approved under the Production Part Approval Process (PPAP) are to be shipped directly to the receiving location to meet the procuring divisions’ shipping schedule and are exempt from the documentation requirements stated in this procedure. A five (5) piece layout is to be included with every shipment unless otherwise specified by the procuring division in writing. These production approved parts must be identified with a Prototype Material Tag and the shipping container identified with a Prototype Material Label. Parts that do not meet design record requirements will be subject to a Discrepant Material Report requesting a corrective action plan(s) submitted in an 8-D format.
The following ten (10) items shall be included with a level one submission.
□ Parts
□ Warrant
□ Design Record
