TOP-CDCHG: Heat Code Changes

Rev: 12/06/2017

Scope: This procedure covers the changing of heat codes during a forge die run. Code changes occur when all of the steel cut from one heat code have been forged and the job will continue with another.

WHAT TO DO

1 Production Leadman As walk past furnaces Container; Traveler Check to see if code changes will be coming up soon and notify the Hammerman and his crew.

2 Furnace Operator (double- checked by Hammerman) Upon completing a container of steel Container; Traveler Check tag on next container; be sure containers for a heat code are run in order; if the new container has a different heat code from the current one, be sure the current tag shows that it completes the heat code and notify the Hammerman or someone on the crew of the code change; clearly separate the steel from one heat to the next so they never get close to each other in the furnace; DO NOT LET THE HAMMERMAN HAVE STEEL OF THE NEW HEAT CODE UNTIL THE DIE IS RESTAMPED, (or until the new parts container is tagged and in place); notify Die Shop if hot stamping required; if not required, go to step 4; keep jobs that do not require heat code markings in separate containers and identified with the container.

3 Die Shop Helper When die is ready for hot stamping Traveler; trim tooling marking Insert stamp or cassette in trim tooling.

4 Hammerman At the end of steel for one heat code
Container; notification from Furnace Operator Stop forging...DO NOT FORGE PARTS WITH A WRONG HEAT CODE; prop the ram; pull out the top die if it has heat code stamping; get the Die Shop Helper, the Hammerman or Die Prep Helper to restamp the die for the new heat code; make sure that all stamping info on Traveler matches Customer Specifications (Example: part numbers and material symbols); have the parts container pulled out so the new heat code goes into a new container; be sure that the new container is tagged with the right heat code

5 Hammerman As forging job is completed Container; Traveler; own knowledge Before changing heat codes count all scrap on disposition table and record on Hammer Scrap Logs; scan quantity into M2M; forward Hammerlogs and Hammer Scrap Logs to Production Supervisor for review

6 Production Supervisors Upon receiving Hammerlogs and Hammer Scrap Logs Hammerlogs and Hammer Scrap Logs Review Hammerlogs and Hammer Scrap Logs for causes of any scrap; after review forward to Materials Clerk.

7 Materials Clerk Upon receiving Hammerlogs and Hammer Scrap Logs Hammerlogs and Hammer Scrap Logs Enter scrap cause from Hammer Scrap Logs into M2M; file Hammerlogs and Hammer Scrap Log in the Hammerlog files.

8 Die Shop Worker or Hammer Crewman assigned by Production Supervisor After ram is propped and top die out (if needed) Traveler for new code; Tub/buggy tag Verify that the Traveler has the same heat code as the container; restamp the die per print (if any); double check all stamping; turn the die back over to the Hammerman; sign the Traveler and hang it up on the clipboard with initial Hammerlog.

9 Hammerman and QC Inspector After die is restamped Traveler for new code; Container Set the hammer back up and forge the first part with steel of the new heat code; compare the lettering to be sure it is the same code as on the tag for the new heat code and on the Steelyard Traveler; IF THE DIE IS NOT STAMPED RIGHT, IMMEDIATELY GIVE ANY PART WITH BAD LETTERING TO THE QC Inspector TO HAND-RESTAMP AND GO BACK TO STEP 2; after ensuring that all codes agree, start a new line on the Hammerlog showing the new heat code ("code letter") in the die, on the container tag and on the Traveler, then resume forging; if OK, QC Inspector must sign off paperwork before running production.
