TOP-GAGES: Gage Control

REV:11/01/07
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.)

STEP WHO WHEN INFO TO USE WHAT TO DO RESULTS
IF GAGE PROVIDED BY CUSTOMER, SKIP TO STEP 3
1 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 Sketch or other info to Machinist describing desired gage; Job Order initiated; controlled print(s)
2 Machinist Per schedule agreed to with Engineer Job Order; Print, Sketch or other info Make gage to specifications Finished gage returned to Metrologist
3 Calibrations Clerk** Inspection after every 4 times it has been checked out (every 4th time would start the year over); Inspect on a yearly basis those that have been used less than 4 times; unless they have not been used at all; Or anytime a gaged dimension is changed on a print Print(s); gage; gage status record

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; 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; if gage being returned after use in inspection is found to be out of tolerance, report per TOP-RECHK Bad gages red tagged and validity of any inspections made with bad gages brought into question via TOP-RECHK for new or disapproved gages, dimensional report to Engineer; if gage approved, go to step 6
4 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 Engineer Once gage fully approved null Turn gage over to Calibrations Clerk for Gage Control System Approved gage ready for storage
6 Calibrations Clerk Upon having verified gage Forging or machining print; gage Mark gage and attach calibration sticker; enter gage into Gage Control System; includes customer gage (customer gage identified as such) ;apply any safeguard which is deemed appropriate to safeguard the gage from adjustments which would invalidate the calibration; attach Gage Post-it note to master forging or machining drawing; if reference gage++ record wear dimension(s) in Gage Control System Notify QA Manager of gage approval Tagged gage in controlled storage marked with die number and print revision; Customer gage identified and processed in system; Recorded wear dimensions in Gage Wear Record; gage safeguarded if appropriate; Gage post-it on master drawing; any obsolete check-out note removed from gage storage area; QA Manager notified of approval
7 Engineering Assistant Upon encountering gage post-it 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 Division) Make verbal or written request to Metrologist to check out gage Request made to check out gage
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. Gage(s) accounted for while checked out
10 Calibrations Clerk Upon Calibrations Clerk's review of Gage Control System Gage Control System Notify QC Supervisor to have a designated team member return gage(s) Gage(s) returned
11 Calibrations Clerk Upon request to check out gage Gage Control System; gage Ensure that person checking out gage fills out gage checkout slip; update Gage Control System Gage Control system updated to show gage checked out*; gage in care of person checking it out; note in gage storage area showing who has the gage
12 Calibrations Clerk At least every 2 weeks Calibration file Review status of each gage checked out with person who checked it out Gages not lost or forgotten
13 Designated team member When through with gage null Return gage to Calibrations Clerk; GO BACK TO STEP 3 Gage back in Calibrations Clerk's hands

"Engineer" refers to the member of the Engineering Department assigned the die in question. If there is any question as to which 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.
