1. General

1.1 Purpose

The purpose of this document is to identify the requirements for Herman Miller, Inc., purchased tooling located at supplier sites. Tooling requirements include maintenance, tool identification, and asset tracking requirements. Planned maintenance is identified under maintenance requirements in an effort to:

• Improve reliability • Improve quality • Forecast tooling repair or replacement

1.2 Scope

These requirements apply to all HMI-owned tooling and equipment located, operated, and maintained by suppliers or their subcontractors and used in the manufacture of HMI products or component parts.

1.3 Reference Documents

The following documents are identified as supplemental standards or guidelines. These must be adhered to as they apply.

• PUR-TOOL-PRO-011: Stamping Die Tooling Standards • PUR-TOOL-PRO-010: Injection Mold Tooling Standards • PUR-TOOL-PRO-009: Rollform Tooling Standards • PUR-TOOL-PRO-008: Custom Tooling and Fixture Standards • PUR-TOOL-PRO-005: Die Cast Tooling Standards • PUR-TOOL-PRO-003: Tooling Purchase Order Generation • PD-ENG-008: Dimensional Verification Guidelines • CORP 4.2: Production Part Approval Process

1.4 Supplier Responsibilities

This document identifies minimum supplier requirements as they pertain to HMI-owned tooling. The supplier must provide all deliverable items to the HMI Tool Engineering Group prior to release to production. Clarification of requirements may be obtained from the HMI Tool Engineering Group.

1.5 Safety Considerations

It is the supplier’s responsibility to produce quality tools within all applicable local, state, and federal safety guidelines. This includes, but is not limited to, the National Fire Protection Agency (NFPA), Occupational Safety and Health Act (OSHA), and within Michigan, the Michigan Occupational Safety and Health Act (MIOSHA) regulations.

of 11 Supplier Tooling Guidelines PUR-TOOL-PRO-006

The supplier must continually ensure the safety and integrity of HMI tooling and equipment to make sure they are maintained. This includes checking that safety switches are working properly and guards remain mounted to the equipment. The supplier is also responsible to follow appropriate safe lockout practices when working on tooling and equipment.

2. Physical Tool Specifications

The RFQ Form should be completed with specifications and submitted to Herman Miller, Inc. Tool Engineering Group prior to release.

3. Tool Maintenance Requirements

3.1 Tooling Replacement/Repair

The supplier will be responsible for the expense of repair or replacement for all tooling components that experience wear or breakage during normal operation for the life of the tool as specified on the tooling purchase order, unless there is agreement otherwise from the HMI Commodity Lead. This includes perishable and non-perishable tooling, up to and including, replacement of the entire tool. Reference section 3.3 for Tool Life Tracking.

3.2 Planned Maintenance Instructions

A planned maintenance program must be in place for all HMI-owned tooling, unless it is deemed unnecessary as agreed to by the HMI Tooling Engineer. The planned maintenance (P.M.) instructions must define each maintenance activity required and may consist of formal instructions or checklists that clearly define and/or reference other documents to allow each task item to be easily understood and performed. See 3.2.1 for minimum requirements. Records of the P.M. activity are to be maintained. Both the P.M. instructions and the completed maintenance forms are to be filed so they can be readily retrieved during the life of the tool.

3.2.1 Maintenance Activity Completion

All maintenance records and schedules for each tool must be kept by the supplier and available to HMI Associates on request.

The maintenance records must identify the following:

• Part number • HMI tooling asset number • HMI tooling number, if applicable • Date that maintenance activities are completed • Technician sign-off • Specific maintenance activities performed • Frequency of activities; by number cycles or time period • Comments regarding general tool condition • Parts repaired and replaced • Total hits, shots, or cycles on tool since inception • Spare parts on hand

3.3 Tool Life Tracking

Tool life must be tracked either by number of hits, shots, or cycles. This information needs to be updated at defined intervals and available upon request. A minimum requirement is that the tool life is identified to the Herman Miller, Inc., Tooling Engineer and Commodity Lead once per year, unless otherwise specified. Additionally, written notice must be given to the Commodity Lead prior to 30 percent useful life remaining, unless the time to initiate and replace/repair the tooling is greater than 30 percent of the tool life. In this latter case, the supplier and HMI Commodity Leader must agree to the tool tracking report frequency. This allows HMI time to inspect the tooling, forecast repair or replacement, and initiate the appropriate action.

Custom equipment or machines must include cycle counters to monitor total machine cycles. A resetable counter may be added, in addition, as an option to identify P.M. activities.

Tooling inspections may be requested at any time by the HMI Tooling Engineer to evaluate the condition of specific tools that may help to forecast any necessary repairs or replacements.

3.4 Tool Storage Requirements

The following elements should be considered when properly storing HMI tooling when not in use:

• Tools must be safely protected from exposure to fire, explosion, corrosive chemicals, etc. • Tools must be sufficiently coated or protected from corrosion, dirt, dust, or any contaminants that can adversely affect the tool function for the duration of storage. • Tools must be protected from material handling damage. • Tools should be positioned in their storage location such that the tool identification is easily visible. • Tools in storage locations are expected to be ready to perform to meet HMI reliability and quality standards. Tool maintenance and repair should be completed prior to storage. • Tools are to be stored such that they can be retrieved quickly and readily when needed for production or as requested by HMI for inspections. The storage system must make it easy to find any HMI tooling.

4. Tool Identification and Asset Tracking Requirements

4.1 Tool Audits

Tool audits will be required to ensure that HMI tools are being properly maintained and inspected as needed. It may also be necessary to perform an audit toward the end of the expected tool life to forecast repair or replacement. A tool audit will consist of the following:

• Verify P.M. plans are clearly identified. • Verify P.M. records are being maintained and controlled. • Ensure proper tool identification. • Verify tool storage practices.

• Verify drawing storage practices. • Inspect condition of tools as needed.

In summary, the tool audit will check conformance to the Supplier Tooling Requirements.

HMI Associates other than the Tooling Engineer may perform tool audits as deemed necessary. The Supplier Quality Engineer may include a tool audit at the time a quality audit is performed.

4.2 Tool Identification

Tool identification information is to be stamped or etched on the tool surface where it can be easily read from a storage or operation location. A storage container must include all appropriate identification only for tooling that does not provide a sufficient etching location due to tooling size. Tags should not be used as they can become damaged or otherwise removed from the tooling, unless otherwise agreed to by the HMI Tooling Engineer.

Identification information must be able to withstand normal production and handling environments, in addition to extreme circumstances.

Tool identification is to include the following information:

• HMI asset number • HMI part/drawing number • Operation description such as progressive die, die cast die, etc. • Production release date • Tool manufacturer

Where applicable, information such as:

• Shut height • Pitch • Stock size • Punch holder weight • Total weight

Sample Identification:

Supplier Job # 8675 Herman Miller Asset # 088825 Herman Miller Part # 136104 Progressive Die Production Release Date 06/01/00 XYZ Tool Manufacturer

Shut Height 42.965” Pitch 6.000” Stock .0897 x 38.250 Punch Holder Weight 15,200 lbs. Total Weight 30,200 lbs.

4.3 Tool Specification Requirements

All procured tooling should adhere to the appropriate tool specification requirements. Any deviations to this must be clearly identified in writing and agreed to by the HMI Tooling Engineer.

Reference the appropriate specifications depending upon the type of tooling.

• PUR-TOOL-PRO-011: Stamping Die Tooling Standards • PUR-TOOL-PRO-010: Injection Mold Tooling Standards • PUR-TOOL-PRO-009: Rollform Tooling Standards • PUR-TOOL-PRO-008: Custom Tooling and Fixture Standards • PUR-TOOL-PRO-012: Die Cast Tooling Standards

4.4 Tool Moves to 2nd or 3rd Tier Suppliers (Initiated by the Supplier)

The HMI Commodity Team must first approve any tool moves initiated by the supplier. The Commodity Team will follow appropriate guidelines to ensure quality and reliability for the part(s).

The following information must be provided to the supplier once approval for the tool move is granted.

• Drawings of the tool must be provided if they exist. • Wire burn data must be provided if it exists. • The last part ran from the tool must accompany the tool. • A copy of the last P.M. record must be provided identifying tool life, part number, part revision level, and the latest planned maintenance activity at a minimum. • A first piece layout and 30-piece study may be required to establish a baseline prior to a tooling move.

Additionally, the HMI Tool Engineer must be contacted prior to shipping the tool to review the above information and inspect the tool or send the tool out for inspection as needed.

4.5 Tools Moves Out of a Supplier (Initiated by HMI)

Tooling information required for moves initiated by the HMI Commodity Team will be similar to those moves initiated by the supplier.

The following information must be provided to the supplier once approval for the tool move is granted.

• Drawings of the tool must be provided if they exist. • Wire burn data must be provided if it exists. • The last part ran from the tool must accompany the tool. • A copy of the last P.M. record must be provided identifying tool life, part number, part revision level, and the latest planned maintenance activity. • A first piece layout and 30-piece study may be required to establish a baseline prior to a tooling move.

Additionally, the HMI Tooling Engineer must be contacted prior to shipping the tool to review the above information and inspect the tool or send the tool out for inspection as needed.

4.6 Tool Transfers—Inspection and Tool Life

Tools that are received as a result of a tool move must be properly inspected to determine the condition of the tool relative to the tool life. The HMI Tool Engineer is to be advised when the tool inspection will take place and will be present as deemed necessary. Inspections should take place at a tooling manufacturer or upon receipt of the tooling at the supplier.

The tool life is to be identified during transfer whenever possible. The tool life must then be re-established or re-negotiated with the HMI Commodity Team to identify a consistent set of tool life expectations. It may be necessary to have the tool refurbished to obtain the desired tool life.

The supplier is responsible for tooling replacement as identified in Section 3.1, during the negotiated tool life.

4.7 Tool Obsolescence

Tooling may need to be disposed of for a variety of reasons including:

• HMI part obsolescence. • Tool life is completed and repairs are not feasible. • HMI part design changes requiring new tooling.

The HMI Commodity Lead will determine the need to dispose of tooling. The HMI Tooling Engineer will provide written authorization and instructions as required to dispose of all tooling. Tools that have not been used for a period of time will typically not be obsoleted unless the part drawing indicates the part has been obsoleted, also.

4.8 Tool Design Changes

Tool design changes include any modifications performed to the tooling that can affect the quality or operation of the tool. This does not refer to normal maintenance activities, but rather to changes that affect the tool operation in any way. Examples of this include 1) an HMI part revision change that causes a part dimensional change, 2) the addition of a cavity in a die, or 3) the addition of die protection sensors.

Tool design changes require the involvement of HMI to ensure that PPAP and tooling procedures are followed. The HMI Tool Engineering Group must be involved to update the tooling database with the appropriate changes and verify that the tool integrity and life will not be compromised in any way. Additionally, the supplier is responsible to update tool drawings as applicable.

4.9 Tool Drawing Requirements

Tool drawings are required for all HMI tools, unless otherwise approved by the Tooling Engineer. The drawings can be made to the supplier’s drawing standards provided they are:

• Computer generated and formatted to a DWG, IGES, or DXF format. • Include a bill of materials or stock list. • Include an assembly view as applicable. • Include sufficient detail to reproduce the tool or components as necessary. • Provide wire burn data as supplied by the tool manufacturer.

It is the responsibility of the supplier to ensure the drawings are updated to the latest HMI part revision level. Some tool drawings, such as for mold tooling, only show the base tooling detail and do not show part detail because they are generated directly from HMI drawing models. In these situations, it is acceptable that a general note identifies that the tool drawings apply for all part level revisions. All drawings must be available to HMI Tool Engineers upon request.

4.9.1 HMI Asset Number Identification

The Herman Miller, Inc., Asset Number, supplied with the corresponding purchase order, must be identified on the drawing set. It must be clearly represented as “Herman Miller, Inc., Asset # ______.” If the asset number cannot be easily placed in the title block, it is acceptable to place the information outside the drawing border to the right side of the title block rotated 90 degrees such that it reads vertically.

Example: 6 5 4 3 2 1

Name: #

Material: e s

Approved By: Date: s A

Company Name: Date: c n I

4.9.2 Drawing Storage Requirements

Drawings must be stored to satisfy the following conditions:

• The drawings must be adequately protected from harmful exposure to the environment such as water or heat. • All drawings must be stored electronically at a minimum. • All electronic drawings must be appropriately backed-up to prevent information loss. • The drawings must be organized such that they can be retrieved quickly and easily.

5. Supplier Responsibility Summary Checklist

The following checklist is a summary of the items outlined in this document. The supplier is responsible to:

Supplier Submission Requirements Prior to Tooling Release to Production:

___ Develop planned maintenance instructions and keep them as controlled documents—Section 3.2. ___ Retain records of planned maintenance activities—Section 3.2.1. ___ Provide physical tool specifications for the HMI tool tracking database—Section 2.0.

Supplier General Responsibilities:

___ Replace necessary tooling during the expected tooling life as defined on the tooling purchase order—Section 3.1. ___ Adhere to all applicable reference documents—Section 1.3. ___ Adhere to OSHA requirements to include local, state, or federal guidelines. ___ Track tool life—Section 3.3. ___ Identify tool life to HMI prior to 30 percent useful tool life remaining unless time to initiate and build a replacement tool exceeds 30 percent of tool life—Section 3.3. ___ Store tooling properly—Section 3.4. ___ Identify tooling properly—Section 4.0. ___ Adhere to tooling move requirements if leaving the supplier—Sections 4.3 and 4.4. ___ Inspect tooling upon receipt from another supplier during a tool transfer and establish acceptable tool life with the HMI Commodity Team—Section 4.5. ___ Contact HMI with tool design changes—Section 4.6. ___ Maintain tool drawings, including appropriate HMI asset identification and drawing storage—Section 4.7.

When is a Final Design Review Meeting is Required? All Category 1 parts should have a formal Final Design review Meeting. Some Category 2 parts should have a formal FDR meeting but in some cases (to be determined) it is discretionary. Contact the DSM who kicked off the PO launching the tool build to determine the proper category.

Conducting a Final Design Review When a Formal FDR (Final Design Review) meeting is required 1. The initial tooling PO will launch the design phase of the tool order. It will authorize the purchase of general steel requirements and other long leadtime purchased components. The PO will establish a not to exceed price and leadtime based on a defined Herman Miller part/drawing number that is defined on the PO. 2. At least one week before requesting release to build the tool, the supplier will work with the DSM to schedule a FDR meeting. The minimum attendance will consist of the The Tier 1 supplier, their tooling lead, the DSM, Product Engineer, a Quality/Dimensional Management and/or Performance Engineer. 3. The supplier will conduct and lead the meeting using the HMI checklist as a guide to reviewing the various aspects of tool design. While most of the information on the checklist should be redundant, it is one last opportunity for HMI to review specific design details on both the tool and part. 4. At least 3 days prior to the FDR meeting, the Tier 1 supplier MUST submit: 1. The completed HMI Design Review Checklist (commodity specific). 2. The 3D tool design files in stp format. 3. The Completed Tool Specification Submission Form (commodity specific) 5. At the conclusion of the FDR meeting, if the design is approved, the DSM will provide the Tier 1 supplier with a PO Alteration giving authorization to complete the build. The PO Alteration should always include an updated commitment date for 1st shots and final PPAP. 6. These documents along with any additional supporting information should be submitted via the HMI Tool Engineer's ftp site. Contact the HMI Tool Engineer for access information. 7. These tooling documents should be organized in a single zipped folder for each tool that is submitted. The folder name Must be formatted as illustrated below.

When is a Final Design Review Meeting NOT Required? When a Category 2 part is kicked off, a formal FDR may not be necessary. 1. Depending on the complexity, the DSM may, or may not choose to schedule a FDR meeting. 2. He may choose to use the two phase PO approach listed above or just kick off a complete PO from the inception of the order. 3. In this case, At least 3 days prior to the starting the build, the Tier 1 supplier MUST submit: 1. The completed HMI Design Review Checklist. (commodity specific). 2. The 3D tool design files in stp format. 3. The Completed Tool Specification Submission Form (commodity specific). 4. These documents along with any additional supporting information should be submitted via the HMI Tool Engineer's ftp site. Contact the HMI Tool Engineer for access information. 5. These tooling documents should be organized in a single zipped folder for each tool that is submitted. The folder name Must be formatted as illustrated below.

Terms of Final Payment Before final payment can be made, all the above mentioned data must be submitted and received. Additionally, at the end of the tool build, there are two additional items that must be delivered. 1. The Commodity specify spec sheet filled out completely. Frequently, the information on this sheet is not available at tool launch. Submission of this spec sheet at the conclusion of the tool build insures we have the information we need before the PO is closed out. 2. Additionally, upon the completion of the tool build, we require a photograph of the tool confirming that the tool has been properly scribed and identified as a Herman Miller asset as described in the checklist.

To access the standardized Tooling Checklists and Tool Specification Submission Forms by commodity that are required in the procedure above, please review the Supplier Tooling Guidelines PUR-TOOL-PRO-006 or contact an HMI Tooling Engineer for more detailed support.
