RESULTS

1 Production Supervisor or Leadman ("Foreman") When determines that it is time to set up job after completing TOP-JSTRT and having initial steel cut per TOP-CUTIT and when determining need to change process Production schedule and personal knowledge of shop activities; Steelyard Traveler; Inspection print Check to be sure all preliminaries are ready to begin setup; assign team members as Hammerman and other positions needed for the job and equipment; tell Hammerman any special instructions regarding job based on experience from last run; if needed, notify Die Prep to set up trim/punch tooling; notify QC Specialist if this job is to run on a previously idle hammer; notify Maintenance if special equipment is needed. If process changes notify QC Supervisor or QC Specialist (via e-mail) of need to modify (step-up) inspection; verify and approve the Hotcell. Job assignments made.   QC Supervisor and/or QC Specialist notified when process changed.
2 Hammerman (and others involved in set up) As assigned by Foreman Instructions from Foreman; Hotcell; Inspection print Verify die number on Traveler, match tooling and tub/buggy tag; as soon as setup is complete, forge first parts and inspect for mismatch and heat code letters and part numbers, get first steel heating ; unless the job has already been partially run, and the tub/buggy tag should show this to be the first container for the heat code; start a new line for the job on the hammerlog showing at least the die number and the heat code ("code letter") on the part, on the tub/buggy tag and on the Production Floor Traveler; adjust hammer and make test forgings until match looks good; as soon as possible trim (and punch, hot pad, bend or whatever as required) to produce test pieces and make adjustments until you and QC Inspector, Production Leadman or Production Supervisor agree that part looks good; scrap all defective parts and record them in the Hammer Scrap Log; if test bar is required by the Production Floor Traveler, work with Foreman to ensure that one is produced and marked with Job Order number and heat code; unless specifically ordered by Foreman or QC, do not hold up job waiting for full first-part inspection (the risk of scrap is just not worth the lost production time); Document any changes that deviate from the Hotcell and forward to the Production Supervisor. Job is set up; production setup aids updated as deemed appropriate; hammer log maintained; test bar produced as needed; changes in production are documented on the Hotcell
3 Production Leadman At start-up when first set of production parts are forged Production Floor Traveler, Hot Cell,  and QC Print Validate first forged parts; disposition any parts that are flawed or questionable; contact a QC team member when further assistance is required concerning flawed or questionable parts Set-up, flawed and questionable parts inspected and  separated from production parts
4 Die Prep and Maintenance (as needed) As Foreman reports new job being set up needing their services Foreman request Perform task as quickly as possible, calling on hammer crew for help as needed; if there is any holdup or reason to think the quality of parts produced might be questionable, report to the Foreman immediately Trimmers, special benders and the like set up in concert with production needs
5 Hammerman (and hammer crew under his leadership) After job is set up Personal observation; advice from QC Inspector or others; tub/buggy tags, parts buggy tags; furnace controls; Inspection print ; Production Floor Traveler Run job as productively as possible; keep hammerlogs; Hammerman, Reliefman and Trimmer operator continually watch each hot part for forging defects; periodically check parts against Inspection print to assure compliance; Heater Operator (or Induction Heater Operator), Hammerman and Reliefman continually watch color of steel to prevent over-heats or under- heats; at least once each hour compare heat codes on tub/buggy, Production Floor Traveler and parts buggy; discard flashings into scrap tub, which is to be dumped into scrap bins as soon as full; put a tag on all containers of questionable parts telling job number and heat code; (this step includes parts or billets awaiting reheating); Make sure no parts are left behind the hammer and no billets are left around the furnace; IF THERE IS ANY QUESTION THAT BAD PARTS ARE BEING PRODUCED (OTHER THAN A FEW FROM SIMPLE FORGING ERRORS) STOP FORGING, INFORM QC INSPECTOR AND OTHER CREW MEMBERS, AND HAMMERMAN REPORT TO THE FOREMAN Parts running under crew control unless possible bad parts; hammerlogs
5a Production Supervisor or Steelyard Leadman When a job is pulled, but the order is not completed Production Scheduling, Hammer Logs; Production Floor Traveler Note on Production Floor Traveler the quantity of parts produced at the time the job was pulled; let the Production Control Manager know what buggy letter was pulled, so note can be added to the three day schedule, put the box of steel that was pulled in the steel yard holding area, see Steelyard Leadman Steel box or buggy pulled from production and put into steel yard holding area so we can start with the letter of steel that was pulled and we don't have any shortages or miss any boxes or buggy's of cut steel
6a Hammerman and hammer crew At end of shift Hammerlogs Hammerman submits hammerlogs with the correct die number and die configuration; if test bar is required by Production Floor Traveler, work with Foreman to ensure that one is produced and marked with job number and heat code. Hammerlogs to Foreman  (for use by Foreman; test bar produced as needed
6b Hammerman and hammer crew

 

At the end of each job or at end of shift Production Floor Traveler; hammerlogs All scrap parts are to be placed in the designated scrap barrel or table at each hammer.  The trimmer man is responsible for placing the scrap in the barrel and the hammer man is responsible for obtaining the scrap count from the barrel and recording it on the Hammer Scrap Log and scanning into M2M.  If the Production count does not equal the Steel Yard count, the problem must be resolved at the end of each job. Make sure no parts are left behind the hammer and no billets are left around the furnace. Part count is double checked; scrap is placed in appropriate location and scanned into M2M; No parts left behind hammer and no billets are left around the furnace
7 Hammerman At end of job (or if down) None Report to Foreman for reassignment; On all jobs, at the end of a job take the flash and part from the last piece trimmed to the Production Supervisor, tag with job number; Make sure no parts are left behind the hammer and all billets have been forged. Foreman can reassign crew, last flash and part from job saved; No parts left behind hammer. No billets left over before next job.
8 Production Supervisor or Production Control Manager At end of shift Hammerlogs Review all hammerlogs and Hotcell  submitted for the shift and resolve any questions or irregularities; Review any last piece flash from upset jobs. Hammerlogs verified; Correct billet weight verified
9 Production Control Manager Typically daily Hammerlogs and Hammer Scrap Log Collect hammerlogs and Hammer Scrap Log and forward to Materials Clerk to enter info into computer. Hammerlog and Hammer Scrap Log info forwarded to Materials Clerk
10 Materials Clerk Hammerlogs and Hammer Scrap Log received Hammerlogs and Hammer Scrap Log Enter Hammerlog and Hammer Scrap Log data into M2M. Hammerlog and Hammer Scrap Log data entered
11 All Supervisors At end of pay week (review may be more frequent) Time cards for own department Review all time cards, resolve any questions or irregularities; review and approve hours and positions; submit time cards to the Payroll Clerk. Time cards verified
