TOP-GAGES: Gage Control

Rev: 12/06/2017

Scope: This procedure covers the creation, modification and control of gages, including customer supplied tooling or equipment, used to verify specific dimensions (as opposed to general-purpose instruments such as calipers whose control is covered by TOP-CALIB.)

Procedure:

STEP WHO WHEN INFO TO USE WHAT TO DO

IF GAGE PROVIDED BY CUSTOMER, SKIP TO STEP 3

1 Forging Engineer* As required for new die sale, engineering change or QC need Print(s) and other info deemed appropriate Explain to Machinist what is needed and issue a Job Order; when pulling off prints from the viewer for Job Order purposes, Stamp print(s) per TOP-PRINT.

2 Machinist Per schedule agreed to with Forging Engineer Job Order; Print, Sketch or other info Make gage to specifications. Return finished gage to Calibrations Clerk.

3 Calibrations Clerk Every 6 months
Print(s); gage; Gage Status Record in Calibration System
Note: "gage" might also be a customer supplied tool or piece of equipment.
Thoroughly inspect gage to insure that it properly checks intended dimension(s) and tolerances; record on Gage Wear Report in Calibration System; if reference gage** check for wear (for new one, determine wear tolerances); if thread gage, visually inspect for damage or wear and, as deemed appropriate, verify thread pitch diameter (if outside calibration source is needed for this measurement see TOP-CALIB); mark rejected gage with REJECT tag; for new or disapproved gages, provide dimensional report to Forging Engineer; if gage being returned after use in inspection is found to be out of tolerance report per TOP-RECHK; if gage approved, go to step 6

4 Forging Engineer IF GAGE IS DISAPPROVED BY CALIBRATIONS CLERK Print(s), Customer Specifications Determine degree of changes needed to gage. Go back to step 1, or determine course of action with customer if customer-provided gage.

5 Forging Engineer Once gage fully approved - Turn gage over to Calibrations Clerk for Calibration System .

6 Calibrations Clerk Upon having verified gage Forging or machining print; gage Mark Trinity Forge gages (with laser etch/telesis to include die number) and attach Calibration Sticker; enter gage into Calibration System ; includes customer gage (if gage not already identified from customer, request authorization from customer to mark gage with laser etch/telesis to identify with customer name and our die number, gage identified as such); apply any safeguard which is deemed appropriate to safeguard the gage from adjustments which would invalidate the calibration; attach Calibration Sticker to gage; if reference gage** record wear dimension(s) in Gage Status Record in Calibration System.

7 Engineering Assistant Upon encountering Gage Label on revised drawing Master forging or machining drawing Notify Calibrations Clerk that drawing has been changed. GO BACK TO STEP 3.

8 Any team member As needed to check out gage (typically to use for production job) Die number of job to be gaged (typically from Shop Schedule in Forge Division, Operation Order in Machining Department) listed on Checkout Sheet Write information on Measuring Instrument Verification Log.

9 Any team member Forge Division: whenever gages are checked out to QC or Production Departments Gage(s) Keep all gages checked out for QC or Production stored in QC Inspection area when not in use, until ready to return to Calibrations Clerk.

10 Calibrations Clerk Upon Calibrations Clerk's review of Measuring Instrument Verification Log. Measuring Instrument Verification Log Notify QC Supervisor to have a designated team member return gage(s).

11 Calibrations Clerk Upon request to check out gage Calibration System; gage Ensure that person checking out gage fills out Measuring Instrument Verification Log.

12 Calibrations Clerk At least every 2 weeks Calibration System Review status of each gage checked out with person who checked it out.

13 Designated team member When through with gage - Return gage to Calibrations Clerk; GO BACK TO STEP 3.

* " Forging Engineer" refers to the member of the Engineering Department assigned the die in question. If there is any question as to which Forging Engineer is assigned a particular die, the Engineering Manager decides.

** A "reference gage" is an uncalibrated device, typically a mating piece provided by the customer, which simply provides a cross-check on the functionality of the part. Although reference gages are not controlled by print dimensions, they are tracked in the gage control system to detect wear.
